quickdtoo There appears to be no SAAMI spec for the 45 Colt rifle, just the revolver which shows a groove spec of .450" with +.004" tolerance.

gcrank1 For cast bullets the first thing to do is fully fire-form some brass in it. Then you can find out the max size cast bullet you can fit in the brass and chamber. If that doesnt shoot reasonably well you cant go any bigger even IF the groove dia. is bigger unless you oversize ream the chamber at the 'neck/throat'. Try this first before looking for other solutions (ie, isolate the 'problem' IF there is a problem)
This is too easy to try first so most seem to try a whole bunch of other things first causing....frustration. Pretty much been this way since guys started trying to shoot cast bullets in place of the jacketed in any caliber (Ive read about this same stuff in 100yr. old magazine articles).
BTDT a bunch myself until I started doing like I suggest and my cast bullet life has been a lot easier since.
YMMV

I was tired, bitter and disgusted. it's a dust collector probably for life. what a waste of my time and money...

Slug your barrel, or not... JMHO.
Somewhere on here, maybe in the FAQ's, they corrected that issue on the 2007 production barrels. Mine is a 2007 so I should be ok. I'll find out soon I reckon. Ordering .452" XTP's.....

rosewood If you look at ballisticsbytheinch.com, they haven't compared that particular caliber/bullet combination, but you can do some extrapolation from other results.

240grain 44mag (federal hydrashok) is about 1380 fps in a 6" barrel, in a 18" barrel, it does 1643. That is about 260fps or so gain in 12". The trend on most of these pistol calibers is you get appreciable gains in velocity up to about 12", after that, the gains are minimal, sometimes, you even lose velocity.

dinny Hornady rates the 250gr XTP for 800-1600fps. From a 20" Handi barrel those velocities can be exceeded.

Thanks, Dinny

Thanks for that. Any ideas of what velocity I can expect? I have scoured the internet and can only find pistol velocities.

greg916 Granted, I have not shot any XTP Magnum bullets at pigs. But then again, I don't need to. The hard cast SWC with it's sharp edges cuts a nice hole through the gristle plate and has enough weight that it usually gives complete pass through. The hole stays open as well. Lots of air in and blood out. Pigs expire quickly. Why mess with something that works?

The XTP with it's rounded profile, especially if it doesn't expand, will likely punch a hole that will close up.

I like the Hornady XTP. Use them in 9mm, 38, 357, 44, and the 45. It's a good defensive bullet and it does work well on deer if you hit them where they live.

That was my point, penetration shouldn't be an issue...
