Should i buy a 6.8 spc

Nevertheless, military brass are sticklers for specs—especially since the Vietnam M16 debacle—therefore the pressure issue was a bridge too far. Apparently not the military. While there are reports of the 6. Worse yet, the hubbub of the development of the cartridge spread around the greater gun world. Gunmakers are businesses, and each wanted their slice of the 6. A very big problem.

With so many firearms floating around with the faulty chamber, the governing body had no recourse but to sanction the flawed design. It might have spelled the demise of the cartridge, once folks caught on to its underperformance. Thankfully, help was on the way. If a shooter goes out today and purchases a brand new 6. It was also a labor of love by a number of individuals and companies who had a belief the cartridge could be more.

In retrospect, the fix was pretty simple—. That was what was tacked on, making the grand total of the 6. Additionally, twist rate was incorporated in most new rifles. Problem solved, it should have been clear sailing.

Except that pesky original design loomed over the improvement. This time with ammunition. Hot factory loads for the 6. Liability laws what they are, not many ammo makers have jumped at improving their loads with the chamber.

There have been exceptions. Silver State Armory now owned by Nosler is the 6. One of its most notable, a load boasting a grain Berger VLD Very Low Drag bullet that it claimed stayed supersonic past 1, yards. Impressive, given inherent case capacity limits. Yet, most shooters can expect much more moderate specs from store-bought ammunition. Most factory loads are topped with to grain bullets, sent from the muzzle at anywhere from 2, fps to 2, fps.

In all honesty, for many this is more than enough for most purposes. Thus the reason why handloaders have fallen in love with the exclusivity of the cartridge.

For the most part with most loads, handloading improvements net fps to fps more velocity than factory ammo and expands bullet selection up to grains. Though, there are exceptions.

The more daring have pushed the limits of the cartridge milking as much as 3, fps plus at the muzzle, which is screaming. Yet, shooters should temper their overall expectations over the 6. The Ranger profile barrels from Wilson Combat are ideal if you seek to create a precise, quick-handling, AR long-barrel carbine. The construction material consists of stainless steel Type R for durability.

It uses a mid-length gas system and comes with a. Ranger barrel has a combination of 1. These barrels are manufactured in line with military specifications, but some users have complaints regarding wrongly cut chambers. Besides its ease of carrying, the barrel also allows you to transition between targets quickly. Item specifics Condition: New: A brand-new, unused, unopened, undamaged item in its original packaging where packaging is Black Hole Weaponry was recently acquired by Columbia River Arms, but the manufacturer continues to leverage cutting edge techniques to create custom rifle barrels.

It also uses arch-shaped rifling to offer gentle valley and hill forms for additional accuracy, enhanced gas cutting, easy cleaning, and increased velocity. Compared to the five-groove rifling alternative, this riffling match style allows for longer barrel precision and accuracy.

The code AR It includes the appropriate rifle-length gas system, straight fluting, and Bull profile. These barrels have successfully undergone MPI magnetic particle inspections and additional nondestructive examination. The match-grade barrel upgrades from Black Hole Weaponry can help you maintain accuracy in continued firing.

Now you can have this superb accuracy without sending your pistol off to a master pistolsmith and waiti The manufacturer produces more than 40 different barrel variations classified in six favorite chambering categories.

Nonetheless, if you need to customize your general-purpose use rifle and equip it for home defense, tactical competition, or hunting, the Recon Tactical Profile The configuration allows your rifle to swing quickly and with ease with tactical gunfire while maintaining accuracy. The manufacturing material for the medium-weight match-grade barrel is the R rifle-rated stainless steel, hence an ideal accessory for high rates of fire. We all know if we want to shoot a lot, there are FAR better alternatives.

Some of you guys really need to read. Taken from this article by Dr. You'll notice that there is a gelatin shot of the 6. BOTH 6. Forest Save Cav-Arms! I hope you don't mind I fixed your comment.

IMHO both are excellent cartridges and bring something to the table. When we have choices the consumer benefits. If you're a reloader and have a bolt gun in a 6.

From what I've seen as a reloader the 6. It's a very easy cartridge to load compared to say. Dealer out of small primers? No problem I'll be loading up my large primer brass today then. Rcd Have a Nice Day.

Not true, not true at all. Neither of my Grendels have any of that done to it and both are fine shooters. Bill A does all that bedding stuff because he believes it's important. If one of those guys was building a highpower rifle in 6.

I do not do it and both my Grendels are good performers. And really, how can you say barrel break-in is caliber specific? You also need to match barrel twist and bullet weight in any rifle you shoot. Sorry if this seems off topic, but I won't let BS like this stand without being disputed in a thread is supposed to be the be all, end all on this topic.

That's great that your experience with 6. That's two data points on opposite ends of the spectrum Here's an interesting article where Bill Alexander talks about barrel twist in 6. There have been threads at 65grendel. He's even gone so far as to say that certain lengths of barrel should have certain twists to maximize accuracy. There doesn't seem to be a need to do this on 6.

I can shoot anything from 85gr to gr through my twist 6. Here's a thread on 65grendel. He specifically mentions that Grendel has a few peculiarities. Again, compared to 6. So Bill A likes to follow strict barrel break-in procedures, how does this have anything to do with a Grendel specific shortcoming?

Lot's of people like to follow strict barrel break-in procedures regardless of the caliber they are shooting. This is personal preference akin to a 9mm vs 45 debate that happens on any forum dedicated to guns and has nothing to do with a 6,8 vs 6. As for twist it is a well known principal that the longer the bullet the faster twist rate is required.

A optimized for shooting grn bullets will suffer accuracy degradation if you try and shoot the larger bullets though it. Bill A is an anal engineer and in the process of looking for performance he has found which twist rates work best with which bullets and offers barrels in different twist rates so YOU can chose based on what you want to shoot.

Again, this has nothing to do with 6. It's a universal truth that applies to all calibers. Don't forget that Black Hills Ammunition also makes match 6. John 6. The extractor has to be tweeked but that is not to hard. IMHO your analysis is off base as there are many more 5. Headspace should not be an issue as it is with the 6. It wasn't designed that way, it's just the nature of the beast. Basically because of the high BC of most 6.

This is a very simple explanation, so I ask that the real Ballisticians on the forum take it easy on me. A short barreled 6. If you talk about military use, I don't think they will clear houses with a 24" barrel and 20ft doesn't give the G much time to finish fast if it starts out slow. If you want to punch paper at distances over yds a grendel has the advantage because it has so many match bullets to choose from.

As all competition shooters load their own for best accuracy and would use the best bullets obtainable to do so then compare the best 6.

If you move up to the gr Lapua there will be a larger difference in drop but the will do better with drift. Velocity makes up for a lot of BC and the 6. The bullet i found to work best from the grendel was the gr lapua scenar and would hit fps out of a 22' barrel when pushed to the point of flattening primers with Reloader 10X, your 18" will push that grain bullet to apx and have apx ft lbs energy at yds. To compare to the 18" barrel you have a 6. For hunting and making reliable humane kills on big game the 6.

Thanks, that does make sense. I am assuming the 70" less drop is at yards? That sounds real good, but a little research reveals that that 6. And GSC has a 6. Using it would also add fps to the Grendel number since it's a low friction bullet Make it a mountain. After all, I do own a Grendel, which makes anything I type tainted with a stench of prejudice and secret motives. Perhaps you meant made one small batch at one point in time for one organization?

This from the personal testimony of a certain BH representative. Comparable length barrels yes but, who says we have to use a 8 twist 6 groove barrel when some of us know how to design better performing barrels. The 5. Every cartridge has it's own pressure limit. Bill set the G limit at psi, what Bill thinks is safe for his G has absolutly no bearing on the 6. You guys have been posting the same 4 year old charts of the 6. Performance wise-If you punch paper at long distance the 6.

For a hunting rifle they are close but the 6. For a military rifle the 6. Availability- goes to the 6. There are more parts and accessories avail and from many sources not just 1. Personal "testimony" eh? I did not know you were versed in the FRE Kidding aside. Hm, I guess we have conflicting info,it happens. Match grade, depends on your def.

I agree, "its not lets punch paper at yards" Your not on , the KAC forum or are you I dont see you there or other boards where such shooting discussion takes place the 1K yard variety , those that speak from experience I listen to, but in here, its a free for all most of the time, and what people say here you have to take with a grain usually a table spoon of salt.

As to high quality brass parts and assembly procedures, by many accounts i the SSA ammo and Hornady ammo is in the ball park. Thats about all I can say on the matter. If you dont think so, I guess you have not shot the SSA cartridges, or in the alternative, if you have feel free to let me know the differences you see between it, Hornady, Lapua, Norma and other brass of quality.

I'm open to hearing your experiences regarding this. Edited: because I do not have a secretary to edit my spelling. It has a longer leade, shoots the same ammo, same case, just like a 5.

BTW I am all for dropping the Remington name from the 6. Mudbug, not an unreasonable question TIm W as usual has it right. The very sad fact is that they could never reproduce this performance , after their selection of powder was shown to be temperature sensitive, and after they selected the twist rates used for.

It is astonishing, that Remington didn't know that "varmint weight" bullets of and grains in. They just figured Remington knew what they were doing, so they used the chamber drawings and nominal pressure values for the cartridge that Remington gave them On the other hand, 6.

So, while the 6. As you can see in the photo below, the 6. First, the two cartridges have the same overall length: 2.

The AR can only accommodate cartridges up to 2. For these reasons, case capacity for the two cartridges is similar, but the 6. Each cartridge also uses different diameter bullets:. Most 6. Those differences in the external dimensions of the 6. This is illustrated in the table below comparing Hornady factory ammunition. Note that Hornady advertises a velocity of 2,fps for this particular 6. At the same time, they advertise a velocity of 2,fps for their 6. As you can see, the 6. This is due to the fact that this particular load uses a heavier bullet with a higher ballistic coefficient and a faster muzzle velocity.

Additionally, that particular 6. In that case, the 6. At yards, the 6. All that being said, the gap in performance between the cartridges is pretty minimal at ranges inside yards. The chart below compares how much a 10 mile per hour crosswind impacts those same 6.

Once again we see that the 6. This holds true for both barrel lengths, though the gap in performance is smaller when the 6. The table below compares the recoil produced by very similar loads to the ones compared above for each cartridge when fired from identical rifles. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges.

As you can see, both cartridges have very mild recoil, but the 6. Specifically, the 6. Trajectories and retained kinetic energy are similar at typical hunting ranges when both cartridges are fired from the same length barrel. This is especially remarkable considering that the cartridge packs that level of performance into a very small package that can still fit in the relatively tight constraints of the AR platform.

Though it does have more recoil than the 6. Additionally, the 6. Since it utilizes. While the 6. Remember: the situation changes quite a bit when comparing the performance of those cartridges from rifles with the same barrel length.

However, while the 6. Specifically, the larger diameter.
