Zak Smith Posted October 7, 2003 Share Posted October 7, 2003 Does 10mm have any utility? It should be a little more flexible for ballistics than "long 40", but will cost more for brass. -z Link to comment Share on other sites More sharing options...
ErikW Posted October 7, 2003 Share Posted October 7, 2003 Utility for what? For most forms of pistol competition (excepting pins or silhouettes), the Short and Wimpy has got the mighty ten beat. One possible reason I can think of to go with the 10mm is the large primer. If you primarily load .45 or .308 or some large primer round on your press, the 10mm might be a good option to avoid changing priming systems. I thought about building a 10mm when I was going to build my first Limited gun. I'm glad I didn't. Fears about the .40 proved unfounded (no case failure to date, knock on wood) and the brass is hella cheaper. Link to comment Share on other sites More sharing options...

benos Posted October 7, 2003 Share Posted October 7, 2003 Other than for hunting, the only time I've heard of the 10mm having any advantage is, for some reason, (and I can't elaborate any further), it seems to run better in a single stack, which are notoriously difficult to make reliable in the 40. This gospel is according to the great Arnt Mhyre... be Link to comment Share on other sites More sharing options...
Patrick Sweeney Posted October 8, 2003 Share Posted October 8, 2003 The 10mm had a small but avid following in pin shooting due to greater power for pin loads. And no problems feeding. But the .45 could be pumped up enough, and was so much easier to find brass, magazines, etc for that thge advantage of the 10mm was not worth the hassle. If I had one (I have several, in fact) I would not hesitate to use it in competition. But as a primary choice, no. Link to comment Share on other sites More sharing options...
Zak Smith Posted October 8, 2003 Author Share Posted October 8, 2003 Well, maybe when I finally get a .40 SV built, I'll get a second barrel for 10mm - for fun. -z Link to comment Share on other sites More sharing options...
Bill Schwab Posted October 8, 2003 Share Posted October 8, 2003 Well, maybe when I finally get a .40 SV built, I'll get a second barrel for 10mm - for fun.-z That's what I did...EGW built a singletstack 40 for me and it was a piece of cake for them to fit a second barrel in 10mm.

Chuck D Posted October 8, 2003 Share Posted October 8, 2003 I'm not so sure that I'd discount the option of a 10mm Limited Gun. I'm not a big fan of 40...and the 10 has TONS of loads with a variety of bullet weights in your common everyday reloading manual that go nowhere near the peak of the C.U.P. pressure scale. Maybe on my new blaster......? Link to comment Share on other sites More sharing options...
Zak Smith Posted October 8, 2003 Author Share Posted October 8, 2003 Chuck D, That was my original thought. The "long" .40SW loads aren't qute as long as the standard OAL for 10mm, which would make making PF at lower pressure easier. -z Link to comment Share on other sites More sharing options...
MoNsTeR Posted October 8, 2003 Share Posted October 8, 2003 Just an amusing observation... I've seen a number of posts and articles saying "Nah, not many people will ditch .38 Super and 9x23 for 9mm Major just for the cheaper brass. We're shooting $3000 guns, who cares about a few bucks saved on brass?" Then as soon as someone suggests shooting 10mm in Limited, everyone says "but the brass is more expensive!"

eric nielsen Posted October 9, 2003 Share Posted October 9, 2003 The 10mm does run much better in a singlestack than the .40 at any length. A good gunsmith can MAKE the .40 reliable but he has to get a lot of things perfect. It was several years in the early 90's before Para and STI finally worked the bugs out of the .40 long length and sold the guns. I shot the 10mm a lot and loved it. However, if you want to reload another caliber with the SMALL primer (38super, the 9mm's) then that's a great reason to NOT load 10mm. I put 20 loadings and more on the 10mm cases, and shooters would give me back 99% of all the cases I shot at matches. "You're the guy who shoots 10mm, right? Here you go." Guys on other squads even. dvc - eric - a28026 Link to comment Share on other sites More sharing options...
Zak Smith Posted October 9, 2003 Author Share Posted October 9, 2003 I don't really care about the small primer vs. large primer. I already have presses set up for 9x19 and .45ACP. -z Link to comment Share on other sites More sharing options...
Chuck D Posted October 10, 2003 Share Posted October 10, 2003 Lots of guys load the 40 with great success. I'd rather pick a load from a manual, DOWNLOAD it to make major with gunpowders that are easy to find at the local shop and shoot. The 10mm and the 45 acp allow me to do just that wherein the 40 is a bit more particular. Cheap brass isn't an issue, my comfortability with the "safety" factor is an issue. Call me lazy....

twix Posted October 10, 2003 Share Posted October 10, 2003 Any thoughts on what to do for mags for a wide body 10mm S_I? Or single stack? I like Bill Schwabs idea too. Tom Bergman Link to comment Share on other sites More sharing options...
Zak Smith Posted October 10, 2003 Author Share Posted October 10, 2003 I thought regular .40 SV/STI mags would work fine with 10mm. Link to comment Share on other sites More sharing options...
Guest Larry Cazes Posted October 10, 2003 Share Posted October 10, 2003 Chuck, I agree about the comfort factor with .45 and 10mm versus .40sw. I have witnessed friends have 4 ugly casehead failures with .40sw over the last 18 months and those were in fully supported chambers. I have loaded over 15K rounds of .45acp using range brass some of which has been loaded 20+ times and the worst I've experienced is split necks that were not even apparent until I inspected the cases. I load for both myself and my wife and am much more comfortable with the pressure margin of the .45. Link to comment Share on other sites More sharing options...
DougCarden Posted October 12, 2003 Share Posted October 12, 2003 10mm works fine in properly set up .40 sti mags, in my guns anyway. I have a STI .40 widebody and a 10mm widebody comp gun for pins. I use the same mags 100%. Mr. Sweeney is right on the money for Pins, but I can run my 10mm with 180s at 195 PF a helluva lot faster on single fastest table and 10Pin than I can in .45, but then again it might be in my head Doug Link to comment Share on other sites More sharing options...
