Not sure how well the 3 groove compares to the others but all of mine are 3 grooves and attain normal speeds with no fuss. They’ve been pretty easy barrels to get smoothed out as well DF. I’ve literally just shot them and once they hit around 50-75 rounds I’ll clean em down to steel and DBC them. After that life has been pretty easy.
I think you’d be hard pressed to find a Bullet that doesn’t work well in a 358 for deer. It just doesn’t have the juice to tear most of them apart like a Whelen or bigger magnum could. The lighter bullets seem pretty neat though. I wouldn’t mind trying a few thru my 358, just for grins.
