10mm to 45 Super in Alaska

[Alaska]

I went from a 44 Mag to the Glock 20 about 13 years ago for Bear Protection in Alaska and about 3 years ago purchased a G21 Gen 4 and set it up to handle 45 ACP +P to lower level 45 Super. Liked it so much it’s my primary sidearm in Bear Country
8.0 of Longshot with 250gr RNFP Hardcast in WW Cases with Fed 150 primer.

The .45 Super is certainly capable. The 255 grain hard cast loads penetrate nearly as deep as the hot 10mm and leave a bigger hole while doing it.

I handload the 45 ACP + P at lower 45 Super levels. For the width of the largest interior grizzly I will have no problem with enough penetration with the correct bullets. I have had excellent results with RimRock TS 250gr RNFN . Yes I like the bigger hole especially on bears. Another good bullet is the 200gr Lehigh Pent Bullet with 8.1 of LS sheds very little weight and penetration 25” plus.

I have a Springfield 1911 that I made 45 Super capable. I enjoy it very much. I Added a ported 6” barrel to a 5” slide. Added a recoil buffer and a heavier Wolf hammer, and went from the stock 16 lb to a 20 lb recoil spring. I’m getting 1239 fps with Underwood, 45 Super 230 grain Gold Dot loads. It’s actually nice to shoot. I’d rate recoil as a little less than a 41 Mag. It’s also easy to switch back to the 5” match barrel and stock recoil spring when not hunting with it, and using 45 ACP loads.

.Sounds like a great set up. You've got the best of both worlds.

Don’t recommend 230 GD for hunting game
Only recommend Hornady 250gr XTP or Hornady 240 MAG XTP for deer size game and hog / black bear. These bullets are designed for 45 Colt / 454 velocity levels which are closer to your 45 Super levels in velocity and will give better penetration and better weight retention for game.

I don’t take extended distance shots at game. It’s bowhunting ranges for me. I put one of the GD 230’s through both lungs of a Whitetail at 20 yards with exit 4-5 years ago. I agree though. If I were going for anything bigger or defense I would go with 255 grain hard casts.

45 Super
250gr (.452) Hornady XTP @ 1210fps:
This load penetrated 22.5" in calibrated gel and made one of the longest permanent cavities I've seen from a handgun: 1"+ wide by 11" long! This is the 1st of two 14" long Blocks. Bullet settled down to caliber size hole for the remaining 8.5" in the next block. Expanded diameter averaged about .68. Retained weight of 240gr. This is not a max load and bullet seems like it can handle some more velocity. This is a very accurate load (three shots into ~.6” at 17 yards, or about 3.5 MOA!) and not too bad in recoil. For Deer and Black Bear I see no better bullet for the 45 Super than the 250gr XTP.

Similar results with 240 Mag XTP

Brass DO not use + P brass for 45 Super loads
I like to keep my loads around the 700 FPE level in 10mm and 45 Super

Thank you. Good information. I may have to work up a good hunting load.

Thank you. Good information. I may have to work up a good hunting load.

I work my 10mm and 45 Super loads up to the 700 FPE area and stop. Here in Alaska for Grizzly protection I don’t use Hollow Points. It’s deep penetration bullets like Hardcast like RimRock TS bullets heavy bullets. The Glock 20 in 10mm is very popular here in Alaska very few carry 45 Super. I seen a big transition from big bore heavy revolvers to the Glock 20 in Alaska several years ago especially since you could buy 2 Glock 20 for one 44 Mag Revolver.
