Home Forums Hunting & Shooting AR and Tactical Rifles AR10 in .358 Winchester?

Why don't you just rebore a 308 in the guise you want? Am assuming just bore and chamber original barrel with same headspace?

I have read a lot of stories about bigger diameter bullets. Guys in Africa say a bigger hole going in and out makes a bigger blood trail to follow to find a shot animal. Too small a hole and the trail gets lost in the dust. If range is not an issue, that is why people like bigger holes. A 358 would be about the largest realistic round for an AR-10 unless someone cuts off the neck of the 308 and makes a short 45 caliber something or other to fit the magazine well. Then it would be like the 45-70 or 444.

The 358 is not a short range round, it loses very little to the 308.

Until you start loading target rounds.

Larger bullet? .458 SOCOM !

I realize the 358 is not a "short" range weapon, but 250 yards or less it is good. I have a 35 Whelen. The 308 is more accurate at longer ranges same as the 30-06 vs the 35 Whelen. The bigger holes they make in under 250 yard shots is better for blood trails. The 358 would be cheaper to reload for than the 458 Socom. Smaller bullets, less powder, and you can form the brass from 308 brass which is more plentiful. I make my 35 Whelen brass from 30-06 cases. Although you can use 45-70 bullets for the Socom, but offhand shooting accuracy is probably less than 150 yards. Depends on what you are hunting and where. A 358 would be a good caliber for the AR-10 variants because it would use the same bolt and magazines as the 308. Same with the 243, 260, 7mm08, and 338 Federal. Nothing wrong with the 308 for anything in North America. I know the 35 Whelen and the 358 are popular with hunters in Canada and Alaska for moose and big bears short of a magnum.
