Semi-Wadcutters in 10mm Glocks

[Palladan44]

I'm venturing to potentially shoot in some Bullseye matches starting this spring, and id like to keep my options open on the weapons to consider for these purposes. "Something always might be better out there, and you'll never know until you try it" has been my thinking on the matter.

Up until now, I admit that my handloading for 10mm has been primarily focused on getting the most bang-for-buck out of the caliber. I've yet to make a load that fires a 180gr projectile less than 1,200 fps in fact most of the loads have exceeded 1,300fps out of m 6" Glock 40MOS
These loads being middle to max published data for powders like Longshot, Power Pistol, Blue Dot and AA#9 with jacketed 180 grain projectiles.

I'm now ready to consider using my Glock 40 MOS (with Afrermarket Alpha Wolf barrel with regular land/groove rifling to shoot raw cast/lead and better chamber support) as a bullseye match gun. It has a nice long sight radius, 6" barrel, heavy long slide.....and I'm most accustomed to shooting Glocks more than any other handgun...shooting 17s, 19s and 34s for who knows how many tens of thousands of rounds over about a 20 year period.

I'd like to develop a 10mm target load using 165 or 180gr SWC possibly from Missouri bullet co. Or SNS casting. Powders I have on hand I'd consider using are WW-231 (1st choice) or CFE Pistol (2nd choice) or a light end Power Pistol (3rd choice)

If I can shoot groups as good or better than I can with my other semi-autos (due to the longer sight radius and barrel) then this would win the vote. Note: I'm guessing these loads would be around 750-850 fps. But could vary, depends on accuracy and cycling reliability.

Any experiences with these bullets in 10mm Glocks or other 10mms for that matter?
I've used SWC in 45 autos and I don't recall issues.

The 231 may be a little slow for this application. Normally you want a fast burn powder like BE, WST, TG to make your gun operate correctly. In any case you may need to do a spring change to get function. I would stick to the 185gr SWC if it was me. The heavier bullet will help with the action.

I have not loaded for the 10 mm, this is from experience with the 45acp and 9mm.

I was under the impression that W-231 was a faster burning powder, but not as fast as say Red Dot.
In fact, W-231 is the quickest burning powder I currently have in my inventory.

Load up a mag full with the 231. See how your gun functions. I shoot 200 grain SWC out of my 45acp 1911's.

Been a while since I shot any Bullseye. Is that firearm/caliber allowed per the rules now?

I shot a few 155 gr SWC lead bullets from my 10 mm when I first got into the caliber, which was at least a half-dozen years ago. I think they functioned OK. It was an EAA base-model steel Witness, so not evidence that they'll feed in your Glock.

Is this a non-standard Bullseye match in which you don't have to have a .45?

If you get different springs, you can go as light as you want for target ammo, of course. Since it was my only centerfire pistol at the time, I got a 6# recoil spring for my Witness, and loaded some 140 grain lead FP bullets over 4 grains of Trail Boss. Accuracy was pretty good and recoil was negligible.

Just gotta be certain you swap the springs back before shooting full-house 10 mm again!

It's a pistol league where any firearm with 6" barrel or less is allowed, semi or revolver.

I don't think 750 FPS with a 165 grain bullet will work, but you should be able to find something in the 40 S&W range that will function just fine.
