[QUOTE="alremkin, post: 62225, member: 3345"] My thinking on a big bore rifle is that something around a 450 Rigby would be about right. If medium fast powders could be used to get around 2450 fps with a 500 grain bullet, the barrel could possibly be as short as 20" so a muzle brake could be fitted to give an over all lenght of 22". I'm not sure this is feasible and I'm hoping someone with experience in this area will comment on this. I've seen a Grizzly about 600 lbs shot through the heart lung area run 250' up a hill and die a couple minutes later just over the crest of the hill. And heard from a very reliable friend who shot a Griz many years ago with a 250 gr Nosler through the lungs and have it run into the bush and not die for more than an hour. These bears were in the 6-7 hundred lb range and we see pictures from time to time of bears with a live weight of 1500 lbs. If I ever get the 03:00 call from Mr Horriblis, I want the most powerful gun I can reasonably handle. A short barrel and weight no more than 12 lbs to be able to use it in short quarters. [/QUOTE]
