2024年4月2日 · I think necking up to 308 (and 8.6 BLK....) is a no-brainer and I'm surprised these are still available at this price considering once-fired LC pulldown M80 brass costs over $350/k (plus shipping!). Posted: 7/7/2024 5:43:07 PM EDT

2021年7月14日 · TV 6.8 @ 60kpsi = 3000fps from 20" barrel SIG 6.8 @ 80kpsi = 3000fps from 16" barrel High pressure allows shorter barrels, but also reduces barrel life and prevents the cartridge from being used in standard 7.62 weapons. SIG also has a …

2022年5月26日 · Been reading all the hype on the new 6.8x51 Nowhere can I find any info on the felt recoil Of the new 6.8 round Anyone seen that info listed anywhere? And how does it compare recoil wise to the current 7.62x51 military ammo? With and without the suppressor

2019年9月23日 · "Bachstein Consulting designed the 6.8 Sherwood to meet the level of performance required by the Army for the NGSW program. 6.8 Sherwood has more internal case volume than 7.62mm and other cartridges derived from 7.62mm, allowing for more performance potential. 6.8 Sherwood is compatible with 7.62mm bolts and bolt carriers, no special ...

2022年4月23日 · The 6.8x51mm cartridge sounds really neat, but personally I don’t really like the ‘M5’ it’s primarily chambered in. My only concern about 6.8x51 is parts wear and longevity (especially in a rifle that it wasn’t primarily developed for) since it’s producing around 80k PSI chamber pressure, IIRC.

2024年7月18日 · Quoted: So, most of the hype concerns the SS base utilized to enable MUCH higher chamber pressures. Having burst/pierced primers while experimenting with wildcats, I have to admit, 80,000 psi is a bit out of my personal comfort range pertaining to how thin a primer is.

2018年10月15日 · The 6.8x51 reportedly gets 3,000+FPS out of the MG’s 16” barrel, and is pushing 2,800+FPS from the Carbine’s 13” barrel. The article compares performance of the 6.8x51 cartridge to .270WSM. Of note; “The Machine Gun weighs in at 11.97 lbs, while the Carbine is 8.1 lbs with no Optic or Suppressor.”

2009年5月25日 · With the 6.8 spc with a 110 gr accubond at 2800 fps the 6.8 has over 1000 fpe where the 7.62 has under 800. Believe me that is just bad advise. "Stick witht he7.62x39 unless you want to tinker" Its more like the other way around. Buy a stag 6.8 upper or build a 11 twist upper and buy some SSA 85 gr barnes bulelts and go shoot.

2011年6月26日 · 6.8 SPC can be built at 6# total with a light scope for reasonable $ and with a 16" barrel is a perfect carry rifle. A 6.8 is great for eastern deer and hogs, but several Elk and a black bear have been taken with one. My 90 YO dad used my 6.8 AR15 for a while and liked it so much he ordered a Mini 14 in 6.8. That is all he hunts with now.
