Ron, congratulations on getting ready to hunt with that fine Colt Revolver! As Rey mentioned, a 260 gr bullet from a 45 Colt at 1,000 fps doesn't need much help, it's been taking a lot of game, some much bigger than deer for a very long time.
That load is easy to shoot & hard to slow down once it hits something & all of us want that exit hole on game, it makes life simple when hunting. Deer aren't hard to kill with good bullet placement & the 45 makes short work of them with or without expansion. If you want expansion your cast bullets need to be quite soft but not lead your barrel, you can do that with powder coated bullets.
You can also do it with a HP'ed powder coated bullet now. I'm simply amazed how far I'm penetrating these heavier cast HP's on deer. I've only recovered one & it went almost lengthways on a fork horn muley after breaking the front shoulder on an angle. I did not expect that. I was using a 44 HP at just over 1,000 fps.
I'm almost positive it would work on "most" hogs in a heavy 45 HP, the 278 gr slug, even through the shoulders. The one variable would be if you drove it too fast. I think at the 1,000 fps margin it would be outstanding. I hope Rey tries it. On big hogs, I'm not sure but deer wouldn't stand a chance.
Anyone wanting to try a few, I'll send you a sample. I have red or black.....or red or black!! A gas check is not needed with PC
