Bullet Suggestions for a CVA 45 1:22 twist barrel ?

[Luck13]

Hello all. Have done a little search on this topic and not seeing anything direct yet. New to MZ's and have an Accura MRX .45, 1:22 which will be used for Nevada mulies, hopefully if I can get a good stalk on one in a couple of months. Have been a lifelong shotgunner and avid duck hunter 42 + years, but this is all a brand new can or worms for me.

So far have been attempting to zero with 200 grain saboted SST's and 777 with "meh" results. (Williams precision site) Looking to try something better and get a solid load developed. With this configuration and twist, etc....would appreciate your suggestions ?
Thanks......

What size charge of 777? 2F or 3F 777? And are you swabbing between shots?

I always recommend doing load dev with a scope. Then pull it off, if required to, after you find a good load.

Thanks El-D. Yes 2 solvent patches pushed thru after each shot and it's 3F 777 at 85 grains by volume. Iron sights required here. I'm getting pie plate groups at best at 75 (after a lot of attempts) and probably going to resort to scoping it next (have some help there). Main thing is we're trying to figure out which options for that barrel and twist.

A 22 is a pretty versatile twist for a .45 - much better than 28 twist. I would think you could shoot some pretty long bullets. (I prefer 18 twist - they’ll shoot anything, IMO.)

As for a good .40 saboted mule deer bullet, you can’t beat a Barnes 195 for a lighter bullet. I don’t think I’d recommend a 200 gr SST for a mature muley. Another fantastic option would be the 200 gr .40 Swift A-Frame. You could also think about the mid weight .40 Fury bullets (225 gr or 250 gr).

I would go a little heavier on the powder charge. I like 100+ grV in a .45 with lighter saboted bullets.

Have you examined any of the spent sabots? Are they melted? You may know this, but, heat and sabots don’t mix so in warm/hot weather you’ve got to give the barrel lots of time to cool between shots (think 10-15+ min).

Thanks! Very helpful and I'll have a look at those and give em a try. I understand about the SST’s. Got those for the lower pricing for practice.

As far as the plastic, so far so good. Will give it a good time gap between shots. Fortunately I’m in north Nevada and between that and shooting early in the morning it’s a little cooler.
