Re: 7.62x39 or 6.5 Grendel for pigs?
I just got through developing my 160gr sub sonic load for my Grendel AR with a can. Here in FL it is legal to shoot them at night using a light, laser or other NV device.
The Grendel will do 2,700 fps with a 120 gr Sierra and at or over 3,000 fps with a 107 Sierra. My 160gr loads are for night use on my pond near the road and there are houses across the highway so I want to keep the noise down to a very low roar.
If you were going with an AR upper in 7.62, it would have a .308 barrel and probably be a 1-10 twist. The combo would get you up to 200gr bullets. So between a 150 and a 200 lie a lot of territory.
Of course, the Grendel (6.5 Sporter, 264 LBC, 6.5 Grendel) is a 7.62x39 with the case blown out and about a 40 degree shoulder depending on the origin (Grendel = 35gr Water capacity) so it would be nice to have a 30 based on the Grendel which would in effect be a rimless 30 Harrett in an AR.
There is the 358 ARk (AR kurtz) which is a .358 Grendel and it is a bad boy. Does like 2,300 - 2,400 with a 180.
Those that beat their guns into plows will plow for those that do not.
