rack&roll Posted March 20, 2015 Share Posted March 20, 2015 What COAL is most reliable in 9mm 1911's? Also bullet weight? I'm having trouble in my SA with 124gr round nose loaded fairly long. What length and weight do you find most reliable? Thanks. Link to comment Share on other sites More sharing options...
carsmovies Posted March 20, 2015 Share Posted March 20, 2015 Weight shouldn't make a difference but I think 124gr are preferable cause of the heavier slide weight of 1911's compared to say a cz shadow which likes the recoil of 147gr. Oal I used in my Sti uspsa 1911 was 1.135. Link to comment Share on other sites More sharing options...
Steve RA Posted March 20, 2015 Share Posted March 20, 2015 Do a "Plunk" test and see if the one you test is short or long, then adjust accordingly. Should end up with base of cartridge even with end of barrel hood. Link to comment Share on other sites More sharing options...
Dr. Phil Posted March 20, 2015 Share Posted March 20, 2015 My Fusion has a shorter/tighter chamber. I load them @ 1.120 and it runs fine. Others run all the way out to 1.160 with no problems. +1 on the plunk test. All guns are different... Link to comment Share on other sites More sharing options...

waterboy Posted March 21, 2015 Share Posted March 21, 2015 I'm running 147gr flat points @ 1.130 in my Springer RO with no problems Link to comment Share on other sites More sharing options...
doc88 Posted March 21, 2015 Share Posted March 21, 2015 Trojan 9mm 147gr FP Bayou Bullets 1.145-1.150 OAL. Longer lengths feed better in my Trojans. Link to comment Share on other sites More sharing options...
blind bat Posted March 21, 2015 Share Posted March 21, 2015 OAL is dependent on the bullet's profile. MG JHP's need to be loaded shorted than any other bullet I've tried. As Steve mentioned, do a plunk test with the bullet you want to load, subtract .010" and call it good. Link to comment Share on other sites More sharing options...
ahub3101 Posted March 21, 2015 Share Posted March 21, 2015 147 Bayou at 1.14" in wife's Trojan. It's what I shoot in my Glock so that's what she gets too. Runs perfect, Dawson mags. Link to comment Share on other sites More sharing options...
robertg5322 Posted March 21, 2015 Share Posted March 21, 2015 Running MG 115g FMJ in a Springfielld Loaded 9mm, 1.110"-1.113". Never had an issue over thousands of rounds using Metalform 10 round mags, or the original 9 rounders or the 3 additional free from SA 9 rounders (admittedly these 9 round mags see little use other than dry fire). Use the gun for USPSA Single Stack Minor. Link to comment Share on other sites More sharing options...
wurm Posted March 21, 2015 Share Posted March 21, 2015 I have used 124 grain Montana Gold hollow points in my Springfield Loaded at 1.125 oal as well as 147 grain Montana Golds at 1.135 and both worked great. Link to comment Share on other sites More sharing options...
Postal Bob Posted March 21, 2015 Share Posted March 21, 2015 What oal were you using, and what problems are you experiencing? Before thinking it's the cartridge length causing the problem, look at your feed ramp and the extractor. And sometimes the mags themselves can cause feeding problems. As for mine, I use 124 gr at 1.135-1.150". Link to comment Share on other sites More sharing options...

As for mine, I use 124 gr at 1.135-1.150". The magazine feed lip length plays a big part in relaibility of feeding. From my experience the Wilson 10 round mags with long feed lips are not good for longer OAL's. I found shorter mag lips with longer OAL lengths worked better.

Postal Bob Posted March 22, 2015 Share Posted March 22, 2015 Lots of advice, but the op has left out so much info. First, just what problems is he having? He never said what, we all just assumed feeding. Second, he asks about oal, but doesn't say what he's loading to. Third, what mags is he using? We really need some more information to give him proper advice. Link to comment Share on other sites More sharing options...
rack&roll Posted March 23, 2015 Author Share Posted March 23, 2015 (edited) Well, Mr. Bob. 1. I was having problems initially with my new SA 9mm getting light primer strikes. That issue has been resolved. 2. I then started having the rounds not feeding and sticking on the feed ramp at an angle. I would have to stop, drop the mag (slide was stuck), rack the slide, reinsert mag, rack the slide again to chamber a round and continue firing. 3. Average COAL is: 1.146 4. I never said these were my reloads, I buy them from a local professional reloading co. that I've been using for years. Their price with brass is so low, it almost doesn't make sense for me to reload. (I do have a SDB) 5. Mags are Dawson 10 rounders with No-Gap basepads. Thanks for all the help and suggestions, I think (hope) the problem is resolved now. I put the original recoil spring back in (had a 9lb.) and it's running reliably now. I even tried some AA&A 115gr. reloads, and it ran with those, too. Hopefully this resolves the issue.
