Home Forums Reloading Handgun Reloading 10mm

I have been using AA#9 under 180 xtp and 200 grain cast bullets. Its a case filling powder for a gen 4 Glock 20. The gun shoots as well as I can shoot. I could hit a clay pigeon with it at 50 yards, I can hit a 4 inch circle at 15 that’s about it for me.

I bought this G40 in 2017 to use for hog hunting at night. It has proven itself up to the task. Still using the same two factory loads, Hornady Custom XTP, and Federal Bonded JSP. Both are 180 grain. I can't see any reason to change.

I’m curious how the 38-40 bullets work out n the 10mm. I’ve kicked around trying them but the 180xtp shoots so good I’ve not got away from them.


I’m using 9.2grs of LongShot with the 180xtp. It clocks 1348fps from my 6” storm lake barrel.

NICE! 8.5gr of Longshot under a 200gr XTP is a hell of a hunting load too Men, it runs a bit over 1200 fps in my DW 5" 1911 10mm.

That's pretty much the same load I've been running. I think I was at 8.4g from a long loaded 40 case in a kkm 40 barrel. It was around 1170fps circ.

I hope to thump a hog with my Glock as well. Load is the 180 gr XTP over 14.5 grs of AAC 9.

That’s the same load I use in my Ruger 1911. AA9 and the Hornady 180 XTP. Shoots exceptionally well.

I have the Glock 20 Gen 4. I have dies and components but a little wary of starting the reloading. Getting the smiley face on my once fired brass and have read that Glock barrels do not support the case head. New to reloading auto loaders, should I re barrel with aftermarket?

Smiley faces with what ammo? Yours, someone else's reloads, or factory ammo? Some of the Underwood and similar hot commercial loads can be a little too hot in certain barrels.

The comment you were told about "Glock barrels do not support the case head" is way over-simplified, and also out of date. Pretty much all semi auto pistol barrels lack some case head support at the feed ramp; that's just how it is. Glock was criticized early on for having very generous feed ramps that were less supported than most other brands. However, in the newer guns they've addressed that issue with different feed ramp geometry, and their 10mm barrels now have similar case support to a lot of aftermarket barrels.

It's always possible you got a bad one, but I'd look at the loads first. Personally I would not replace the factory barrel, unless you determine a specific reason to do so, like needing a threaded barrel. The newer Glock barrels are better quality than most of the aftermarket options, in my experience.

Way back when case head support in Glocks was a news item I examined a number of then current production Glock pistols in .40 cal and I could find no significant difference between Glocks and other manufacturers. It is essentially a headspace tolerances issue, and individual pistols even from the same production line will have variation in that regard.

However, the problem was traced primarily to the design of the cartridge case, so it was redesigned, and newer prroduction cases were beefed up to better support the case head area... Federal brass was the primary offender.

I still occasionally see smiley brass laying on the ground at the range, but rarely. Your pistol could be on the long side, but without examining YOUR pistol it can't be determined.

The short answer is to just try a different brand of factory ammo.

If you want to reload, there is no problem, just start with the starting loads in your manual and work up from there and you will be ok.

10mm is a higher pressure round, so if I come across a piece of smiley brass I toss it out, as it has already been stretched in that critical area.

I generally resign once fired brass to less than max loads, and only load max loads in new Starline brass.

They'll work fine. Back in the very early days of 10mm the only cast bullets we could find came from .38-40 molds. I still have some 175 Keith-like SWC's saved from the 80's.

It's a damn good load Burley, I see a lot run the 180 gr XTP's in their 10mm's, don't know how they compare with the 200's, but can say I hit a 275lb buck deer in the last rib at 41 yards, the 200gr xtp at 1200 fps exited clipping the offside shoulder, he walked 20 yards, stood there and died right in front of me, I hope the 180's would at least do that much.

Well I didn't get to kill a hog with my 10mm nighthawk but did kill a Gemsbok at 50 yds and finish 3rd in the bowling pin shoot with it
I was loaded with Underwood 200gr hardcast and it let out a bellow and dropped in it's tracks

Nice.

How do you like your razor?
I’m looking at the viper, venom and razor.

Nice work! Sweet pistol too, looks like you've got it set up right.

Tell me about the frame treatment. Looks nice.

If you got Trijicon suppressor sights, they'll co-witness the red dot. I find it much faster than trying to find the dot without the co-witness irons.

I don't think standard suppressor sights will get there with that setup. MOS setups even with the low profile RMR sight need special MOS-height suppressor sights, and that Razor is a bit taller yet.

Talk to Dawson Precision though, they were offering suppressor sights in various heights to accomodate different setups. You may need to measure yours first.

Nice shooting! A young guy at the range on Friday had one he had just bought, he was very happy with it.

Good info. My Trijicon suppressor sights co-witness the RMR. If other reflex sights require higher irons, then go with the recommended set.
