Glock 10mm Question

[nannyhammer]

I recently received my Glock 40/10mm which will be used as a woods carry gun. I have started working up loads with an Oreo mold (deep HP’s weigh in at 185gr and the shallow HP at 190gr) and a KKM barrel with longshot. I was curious what velocity you guys think would give decent brass life while not performing like a 40 S & W? I’ve looked in my manuals including the Hodgdon annual manual for 10mm data but most data doesn’t cover longshot, my weight boolits or the loads they have are at 40 S & W velocities. I looked around on the net at several sites but some of these guys are trying to turn a 10mm into a 41 mag. Any of you guys have a load that has worked well for you? Feel free to PM me if you don’t want it openly on the forum.

Look at older books. Every new version seems to waterdown the 10mm

My experiance has been about in a factory G20 barrel, pushing a 180 FMJ, CCI350 and Blue Dot i start getting alittle guppied cases at about 1150. With the KKM barrel I've gone up to 1250 with that style of bullet before I started to see the begining signs of a slight buldge. I figure I could get it into the 1300+ neighborhood for my hunting/Yogi-n-Boobo rounds but my work schedule and travel have kept me away. Note that habitual nuclear loaders of the 10mm like to use factory new brass only for one loading before regulating the brass to target/plinking brass backing them down to 1150 of so. There is alot of 10mm loading talk over on the gtalk forum.

I have been able to push 1200fps with 195gr LFP or 200gr plated using BD, 800X, LS & AA#9 all w/o any significant brass expansion in my stock Gen3 20sf. Significant meaning my RCBS dies resize & the round chambers, no visible signs of excessive case expansion. I can't see 180gr jacketed @ 1150fps raising pressures enough to guppy brass with powders slower than PP, but each bbl is diff. Going much beyond that, you are just losing brass to failure. Any case that guppys is done for higher pressure loads, even if you use a bulge buster.

I use .40SW brass in my 10mm, loaded to 10mm OAL and pressure.

IME, Blue Dot can get spikey early in load development with magnum primers.

The Hornady 9th Ed. manual has data with Longshot.

180 xtp from 6.4 - 8.2; 200 xtp @ 5.7-7.3 gr. Longshot.

[Greg S]

I understand now (after the fact) but this was during the powder drought. I had 800x and Bdot available and hand weighed each 800x charge. Now that powders are available again I need to stock up on AA9 and a couple lbs of LS to try it out. I'd better hurry the way Hillary is flapping her gums about gun control trying to.divert atten/? about her own blunders.

[woody402]

I would look at loads using AA#9. I've always had good luck with it in the 10mm or maybe there is load using universal or power pistol.

[Pumpkinheaver]

I load 180 powder coated cast and 180 XTPs with blue dot to 1250 fps. If I need more power than this I'll use a bigger gun.

[jtwodogs]

I have some AA #7 I am going to use in my 10. I know it does not offer the top speed but I think it will do fine with some coated 180 grain flat points from Bayou Bullets. I just got some new Alliant powder BE-86 that is offering top speeds in my .45, looked on their site for info on a 10, nothing for cast lead yet only for jacketed but I am sure that will change once it is out for a while.

[nannyhammer]

Settled at 8.7gr with the 185 HP. Tried a few different loads but 8.7gr seemed to shoot the best groups at 25 yds. Even though this load is almost a full grain under max (Hodgdon manual 8.5 - 9.5gr) it still has plenty of velocity and doesn't seem to be stressing the brass or primers.

[woody402]

Sounds like a good load.

[shooter93]

I use Unique and shoot a 200 grain bullet at 1000 fps. Nice to shoot and it will take care of anything I need to do with a handgun.

[NavyVet1959]

216 gr, 1237 fps
For when the bad guys are standing in a row. Or for hogs... Take your pick...

nanny,

Brass life. Mmm. At the range, that matters. In the woods? You'll be lucky to hardly ever find any, won't you?

Welcome to the forum by the way.

Awh, 'ell... I have trouble enough finding my brass when I fire a test round IN MY GARAGE with all the doors closed. I *think* the brass is in there *somewhere*... But then again, it might be in low earth orbit, come to think of it. :)

My daily carry these days is a full size RIA M1911 in 10mm with my previously mentioned loads.

[nannyhammer]

I think the best description of my shooting habits may be a "brass tightwad". Some how I don't loose much brass except for in the woods and I normally use older brass just for that reason. New brass is just a little too expensive to not make an effort to keep track of. For practice I use a large tarp or a leaf blower to clear out spot. I even use a brass catcher on 6.8 SPC while hunting. Guess that's why I can shoot on 500 pieces of brass for a long time.

[fredj338]

I never worry about brass when hunting, but practice, it's caliber dependent. I'll look long & hard for my 10mm & 6.8 brass. That stuff isn't cheap. I often don't even pick up 9mm or 40, just too much of it at the local ranges for the taking.
Shot some PC & HT coated 195gr this weekend, testing for best accuracy. I still can't get 800x to shoot as well as AA#9 or LS or even BD. Right at 1200fps in my stock G20 with AA#9 & 2" groups @ 15yds, good enough for what I want a G20 for.

[Elkins45]

My woods load is a 200 grain cast FP (water dropped) with 13 grains of AA#9. Gets me right at 1200 fps. I use an aftermarket supported barrel and new Starline brass.
