Flyin40 Posted January 7, 2005 Share Posted January 7, 2005 First I want to say Hello to everyone. First post though I have been reading for about a week. I started Ipsc in 1999 using a single stack 45 open gun. I shot for about 6 months and got up to B class. I bought a STI edge and shot limited also. By the end of the yr I knew I wanted a high cap open gun. I didn't want to put out the money for a complete new gun so I got a new top end built in 40sw. Well that next spring before the snow thawed I had to change work schedules which required me to work weekends. I haven't shot since 99 that much. I'm back to weekends off and had my pistol sent out to get some work done on it. It seems I should of had a 38 super top end built but too late for that. I don't want to spend the money for the barrel and comp plus mags. So heres my question 1.How hard is it to change the 40 top end to a 10mm?? 2.Should I do this?? Is is worth the switch. From what I have been reading its hard to get the 40 sw to make the comp really work unless you use light bullets. With the 10mm I think I would have a little more leeway on bullet weight. It was my first yr shooting and the money investment was huge. Guns, equipment, reloader etc. Made a mistake, should of went with the 38spuper. I will eventually go with a new gun but thats in a coupole of yrs. I figured I was able to make B class with a single stack 45 in open class after 6 months so this gun should be good enough to get me up to at least A then after a yr or two I'll make the switch to 38super.

diehli Posted January 7, 2005 Share Posted January 7, 2005 I'll answer the one question I can: how easy is it? REAL easy. Simply rechamber the barrel for the longer cartridge (cut the chamber longer and give yourself enough lead for the bullet). Link to comment Share on other sites More sharing options...
Caspian_45 Posted January 7, 2005 Share Posted January 7, 2005 I think that the price difference between 40 S&W brass and 10mm brass is something you need to consider. Find a bullet weight and powder combo that works the comp. I'm sure there are several Benoverse people that can put you on to a good load. Do a search in the reloading section will be a good place to start. Link to comment Share on other sites More sharing options...
Flyin40 Posted January 7, 2005 Author Share Posted January 7, 2005 I have aleady search and even went to jmass reloading page, actually I shoot at the same club as him. It seems that 40 bullets in light weight are hard to come by and I have found this to be true after searching the web. When I say hard to come by I mean there is not alot of companies that make them. All kinds of lead/cast bullets. I found Rainers for decent price but several guys say they aren't very accurate. I would have to try them to make sure. I have no doubt I will eventually find a 40 open load that works but I was thinking the 10mm gives me some more room and options. The 10mm brass are only about $6 more per thousand. 38 super brass are cheap compared to 40 and 10, wow. Thks for the help and suggestions Flyin40 Link to comment Share on other sites More sharing options...
spook Posted January 7, 2005 Share Posted January 7, 2005 The 10mm brass are only about $6 more per thousand. Cool. So, where do you get your 10mm brass for $15/1000? Brassmanbrass Link to comment Share on other sites More sharing options...
Caspian_45 Posted January 7, 2005 Share Posted January 7, 2005 Give Montana Gold Bullet Co. a call. 1-800-755-2717 They list 155 gr bullets. Their prices are pretty good. I am not sure where you can find 135 gr bullets, but they can be had. IMHO once fired 40 brass is the way to go. I have not had any problems using them.

shred Posted January 7, 2005 Share Posted January 7, 2005 You can try sticking with .40 if it's what you've got and are set up for. Mr TeamGE himself shoots an Open .40 and does pretty well with it. Link to comment Share on other sites More sharing options...
BigDave Posted January 7, 2005 Share Posted January 7, 2005 Raineer and Berry's both make a plated 135's in 40/10mm, both TMJ and JHP. Nosler and Sierra both make jacketed 135 JHP's that are very accurate out of my SV. Push them at about 1000 fps to take advantage of the BC of those bullets. As for powders, the most reliable i've found has been 4.5 gr of Clays at 1.190". Note, this is for MINOR pf, about 135 actually. This is the load I ran at Bianchi last yeaer. Titegroup gave me absolute fits over the chrono. Brian (Enos) mentioned to me he used to push the Noslers with N320, which is what he shot at the 'Cup also. This also a great ESP load for IDPA in a 1911. I'm sure it would work well for 1911 Society and Steel, too. Link to comment Share on other sites More sharing options...
diehli Posted January 7, 2005 Share Posted January 7, 2005 Beven USED to shoot .40 in Open but has moved on to 9 Major. He used Sinterfire bullets. http://www.sinterfire.com They list 125 and 135 grain frangible, lead-free bullets. The main caveat is that they ain't cheap.

Bruce Posted January 7, 2005 Share Posted January 7, 2005 I will say right up front, I cannot answer any of your load questions...but I do have one of my own: Where are you finding 10mm brass that cheap? I shoot as much 10mm as I do anything else, and sourcing cheap brass has been impossible. If you care to share your source, man, I am all ears! thanks Link to comment Share on other sites More sharing options...
Flyin40 Posted January 7, 2005 Author Share Posted January 7, 2005 He ask the question and his and then answered himself with his name. Just hit his name on his post. Brassmanbrass I just talked to a gunsmith and he stated the 10mm will work the comp more but...... you get more recoil regardless. He said with the 165pf stay with the 40.

Patrick Sweeney Posted January 7, 2005 Share Posted January 7, 2005 The problem seems to be a lack of lightweight bullets at .400" diameter. If that is the case, then changing your pistol to 10mm isn't going to change that. And running 40 in a 1911 platform, you're probably already loading it almost as long as the 10mm anyway. If you are in the short-term position of wanting to shoot Open, but only having a .40 with which to proceed, then don't give yourself ulcers worrying about bullet weight or 40 vs. 10mm. Load the lightest bullets you can reliably lay hands on, to a velocity that gives you major, and get out and shoot. The only "option" 10mm brass gives you is to change your press over to large primers from small. Link to comment Share on other sites More sharing options...
Bruce Posted January 7, 2005 Share Posted January 7, 2005 I don't see that brassmanbrass carries 10mm once fired. On the 10mm load question, you might also check the 10mm guys over on Glocktalk...in the reloading forum. It seems they have run about every option out there, and list many, many loads. Some hot, some not so. Link to comment Share on other sites More sharing options...
shred Posted January 7, 2005 Share Posted January 7, 2005 10mm once-fired is rare enough that most people don't list it as in-stock even if they've got it. I've heard that most of it comes from FBI ranges when they practice with their 10mm MP5's. Link to comment Share on other sites More sharing options...
Flexmoney Posted January 8, 2005 Share Posted January 8, 2005 2.Should I do this?? Is is worth the switch. From what I have been reading its hard to get the 40 sw to make the comp really work unless you use light bullets. With the 10mm I think I would have a little more leeway on bullet weight. I don't see much of an up-side to switching from 40 Open to 10mm Open. Working the comp is about producing gas. That is the idea with going to lighter bullets...it takes more gas to get them moving...thus, more gas to work the comp. 40 is exactly the same caliber as 10mm (both use a 0.400 bullet). So, you aren't getting any more "leeway on bullet weight" by going with a 10mm Stick with what you have now. And, you mentioned Jeff M. Does that mean you shoot at Circleville?

Flyin40 Posted January 8, 2005 Author Share Posted January 8, 2005 Flexmoney, Yes I shoot at circleville. Actually I used to, I started in 1999 but because of my work schedule I couldn't do it any more, I had to work weekends. I shot with Chet Whistle some. He was great with his open gun. Learned alot that first yr only to have to give it up. But......weekends off again so I'll be back at it. Have to get the gun finished first. I just got an email from the gunsmith, seems there might be a problem. I sold all my other pistols to get into ipsc so now I have to wait for my gun back to even get in any practice at all. Can't wait though Flyin40 Link to comment Share on other sites More sharing options...
mcoliver Posted January 8, 2005 Share Posted January 8, 2005 How about using IPSC Modified loads? There are some threads around here where loads were listed by the guys shooting modified. Looking at them shoot, they don't seem to give up much to open shooters except the "short stick." Link to comment Share on other sites More sharing options...
Flexmoney Posted January 8, 2005 Share Posted January 8, 2005 Flyin40, I help run the matches there now. You will have three different matches to choose from (USPSA, Steel, NRA/Biachi). Welcome back...we'll help get you squared away. Link to comment Share on other sites More sharing options...
harm152 Posted January 25, 2005 Share Posted January 25, 2005 There is a company in Utah that offers 10mm Once Fired, it is CENTER STREET BRASS at http://www.csbrass.com/ It isn't too cheap though, $60 per thousand, $50 more per thousand than 40 S&W, but it about the only place online that I have seen that sells once fired 10mm.

Aglifter Posted January 13, 2013 Share Posted January 13, 2013 So, just to clarify, the only difference between 40 and 10MM would be the chambering on the barrel? The window cut in the slide is the same? Link to comment Share on other sites More sharing options...
wgj3 Posted January 13, 2013 Share Posted January 13, 2013 Resurected a 7 yr old thread. Only diff in the actual round is about .2 inches longer case for the 10mm. Bit hotter round though. What early poster was implying was that the two rounds have very similar specs, same bullets, same bore diameter, etc. Please DON'T take a .40 Glock barrel and lengthen the chamber and run 10mm through it.

Aglifter Posted January 13, 2013 Share Posted January 13, 2013 I was thinking about changing an Edge, not a Glock. Link to comment Share on other sites More sharing options...
