Oh. Would you care to explain why?I read an artical in a shooting magazine explaining why the US military should switch to the 6.5 Grendal....
My understanding of the 6.5 is that it's more of a long range round. The 6.8 on the other hand was designed in conjunction with special operations personnel for medium to short range combat.I read an artical in a shooting magazine explaining why the US military should switch to the 6.5 Grendal....
Alot. I own ar's in both calibers. The 6.8 has the same range basically as the 5.56, but at 110 grains is twice the kinetic energy on target. The 6.8 spc was developed for special combat troops for a more effective round on hostiles. It uses a 270 winchester bullet .277 just a lighter weight. The 6.5 uses a .264 bullet and has a better ballistic coefficient than the 6.8, bleeds less energy in trajectory, and is accurate and effective at longer distances than the 6.8 with less energy loss possibly out to 1k yards. Between the 2 the 6.5 has more powder pushing it, te case is fatter but shorter. For me the 6.5 grendel has proven under .5moa at 100 yards, my handloads in my 16" 6.8spc produce .75 at 100. Both are great calibers but if i had to choose just one, it be a 6.5 grendel, then a 6.8spc, then a 5.56.What does the 6.5 do that the 6.8 can't.
The 6.8 SPCs only claim to fame is that the bullet case fit the 5.56/.223 bolt face. Balistically the 6.8 is totally outclassed all the way out to 1000 yds. As a short range hunting round the 6.8 is a good choice but jus compete with 6.5 Grendel. There is something magical about the .264 cal.What does the 6.5 do that the 6.8 can't.
Have been pondering sending my mini 30 to get the caliber swapped to 6.5 grendel, heavy barrel, all.the custom work. Very seriously considering it.Actually the Mini 14 would be a great rifle with a 1-8 twist. Shooting 70 grain bullets with an improved BC. The key to getting them to shoot long distance is the right powder. (velocity) A 20 inch barrel would be real handy but then it looses that carbine feel. The Army spends a lot of time shooting the 77 grain FMJ's out of a 14.5 " barrel both long and short range. Think what it could do in a 16" or an 18.5 inch barrel.
Personally I think the the 6x45 shooting a 70 to 80 grain bullet would be the best of both worlds loaded with the right powder. It apparently was experimented with by the military in the early 60's but the 5.56 won out. If money were no object I have a Mini that could be sent to ASI to find out.
