Howdy folks!
after having persisted for three or four years with 400 grainers to shoot hogs, I just switched to 300 grains bullits.
I tried RCBS 45-405, MP 46-400 solid & Hollow pointed, Accurate 46-400BG, in various alloys, hard and soft, and I had goods results, excellent accuracy, but the boar never dropped in his tracks... (except a very special case). He would always run for his last 30 yards, even when perfectly shot. I've never retrieved a slug in the hogs (except one special case), the bullet goes through, I assume without losing much power.
Same thing last sunday, while a buddy shot one stone dead with his 9,3x74R. His bullet expansed perfectly, reaching the size of my 45, and we found it under the skin of the opposite side.
So I came up with the idea to try 300 grainers, to gain speed, and avoid the "freight train" effect.
Yesterday I was lucky to shoot a hog, not too big (100Lbs), but pretty tough. I shot it from 15 meters, with a RCBS 45-300, weighing 325 grains with my 1/16 lead tin alloy. The boar fell stone dead, and I found the bullet under the skin on the opposite side. It mushroomed perfectly, without any mass loss.
I'm pretty satisfied, I assume the 420 grainers would better suit the huge ones, but I never know their size in advance, nor from what distance I'm to shoot. I think the truth lies in the 350 grains for boars, at least for my way of hunting.
I'm thinking about ordering a new mold from Accurate, but still the RCBS gets the job done...
