tomjerry1 Posted October 15, 2016 Share Posted October 15, 2016 Ok, I have heard of, but have never seen or personally know anyone shooting 40 Long. Is it a 40 loaded to a longer length? 10mm sized shorter? If there is an advantage for it's use, what is it? I'm up for anything that will help, but is it another mouse trap?

kneelingatlas Posted October 15, 2016 Share Posted October 15, 2016 It's just regular 40 brass with the bullet not seated as deep. 1911s are "large frame" guns meaning they're designed for 45/10/38, not 9/40 like "small frame" guns (CZ75, etc.) so in the early days long loaded 9 and 40 feed more reliably than factory length rounds. Now there are a selection of magazines which feed factory length rounds just fine (SVI, MBX, STI with spacer) Link to comment Share on other sites More sharing options...

shred Posted October 15, 2016 Share Posted October 15, 2016 Most STI/SV shooters load their .40 loads longer (around 1.200" plus or minus) for reliability, even with current generation magazines. It also gives less chamber pressure and a tad more safety margin for fast powders. Link to comment Share on other sites More sharing options...
nelson1each Posted October 15, 2016 Share Posted October 15, 2016 I wondered what this "40 long" business was all about when I got into limited with a 2011...now that I've been to the range with both my 40 long loads and factory length ammo I See the difference..Intermittent feeding issues with the shorter ammo. Loading longer...just under 1.2 for me a my lim guns run perfect. Link to comment Share on other sites More sharing options...

resortboarder Posted October 17, 2016 Share Posted October 17, 2016 Factory is 1.135" I believe. My Para Pro Custom 16.40 will feed any length but my STI needs 1.165" or longer. I had chamber gauging issues (bullet slightly crooked) when loading to 1.200" at a rate of 5%, so I've settled in at 1.180". Link to comment Share on other sites More sharing options...
tomjerry1 Posted October 17, 2016 Author Share Posted October 17, 2016 Ok, thaks for the info, guess I've been shooting 40 long the whole time. I load to 1.18, but am thinking of trying longer, winter project. Link to comment Share on other sites More sharing options...
txolds442 Posted October 18, 2016 Share Posted October 18, 2016 (edited) Not to jack your thread. I recently bought a Trojan and bought 5 tripp Corey mags and they haaaaaate 1.135, which I always loaded for my glock and m&p. I'm going to give 1.180 a go, but how long is too long? 180gr blue bullets Edited October 18, 2016 by txolds442 Misspelling Link to comment Share on other sites More sharing options...
blaster113 Posted October 19, 2016 Share Posted October 19, 2016 seems like 1.180 oal is the sweet spot for long loaded .40. The companies selling long load .40 use this oal too. With factory ammo all of my custom .40s (except my first Edge ironically) would occasionally jam. My guns worked just fine at 1.180, I tried 1.20 and I'd occasionally get jams. Don't see the point in going longer than 1.180 if that oal gives near 100% function. Link to comment Share on other sites More sharing options...
Scott Steele Posted October 19, 2016 Share Posted October 19, 2016 I've been set at 1.185" oal without issues.Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
bjones6686 Posted October 20, 2016 Share Posted October 20, 2016 All my 1911's and 2011's run 100% on 40 long ammo loaded to 1.200 OAL. I have Infinity barrels in some of my guns and they come chambered from the factory for 40 long ammo. Link to comment Share on other sites More sharing options...
broadus123 Posted October 23, 2016 Share Posted October 23, 2016 I can load to a oal of 1.20 in my edge as well as my ria. Make sure the bullets you are using are .400. I got a batch of coated bullets a while ago that were sized to .401-.402 and had problems with them. I would get one stuck in the barrel not quite in battery. Had to pop them out. Now I make sure they are sized to .400 Link to comment Share on other sites More sharing options...
jrguar Posted October 26, 2016 Share Posted October 26, 2016 I run 1.185 in mine and never have any problems. Typically I use 180's or 200's with fast powders AA2. You pretty much have to make sure you chamber and lead are cut to work with the longer length then you are good to go. Link to comment Share on other sites More sharing options...
RayUSPSA81 Posted December 30, 2016 Share Posted December 30, 2016 I have had great experience with 1.180s I am thinking about going to 1.200 just to see if there is a difference. Also don't want to reinvent the wheel. Link to comment Share on other sites More sharing options...
jeff40 Posted January 1, 2017 Share Posted January 1, 2017 (edited) I have both STIs and Paras that will feed empty brass, but I load 1.170" in practice ammo (works in glock or M&P) 1.2" with everything else, except 1.225" when using Clays. A gunsmith told me years ago that when pushing pressure limits, or even if you're not, a longer OAL will be more forgiving.

buckaroo45 Posted January 5, 2017 Share Posted January 5, 2017 I had my Para 16-40 throated to accept 1.200. Gave me more reload options and feeds mo betta than stock. BTW, FWIW mine is an early Canadian mfg. Link to comment Share on other sites More sharing options...
sitw Posted January 17, 2017 Share Posted January 17, 2017 My personally built 2011 .40 Limited gun with would not run factory ammo reliably, 1.175 and above OAL ran flawless. After some mag and extractor tuning it now runs everything. I was very surprised to find out how tuning the mag made such a difference. However, the load recipe I like most uses a 1.18 OAL.

jrguar Posted January 18, 2017 Share Posted January 18, 2017 I run 1.185 in my STI , if running a stock 40 barrel you have to have the chamber cut deeper to accommodate the longer length. Link to comment Share on other sites More sharing options...
CrashDodson Posted January 19, 2017 Share Posted January 19, 2017 Its something you just have to play with. Start at 1.2 and work backwards until you can plunk and spin consistently. Somewhere between 1.175 and 1.2 is usually where its at. In one of my SV's 1.2 will cause an occasional jam... Link to comment Share on other sites More sharing options...
