greyhoundman Posted December 10, 2009 Share Posted December 10, 2009 (edited) I am having a little trouble with a Fusion kit I built for a buddy. It is a Fusion 2011.....basically an STI, having allot of trouble getting it to feed reliably using stock 126mm STI mags. It seems like the shorter we load the worse it gets. Tried 1.135 and it still jams frequently, pushed some out to 1.147 and did a little better only jammed twice in 200 rounds but that's still 2 too many. I have already done some finessing to the feed ramp to round out the transition from ramp to chamber a little more. I have seen some recommendations on OAL out to 1.20 for STI style guns and am looking for some input on the best length to try......or work more on the feed ramp and risk becoming unsupported.

Scott Steele Posted December 10, 2009 Share Posted December 10, 2009 I load to 1.190". 40S&W STI. You will find a lot of very good info on .40 loads at general reloading & load data (10mm/.40 cliber) on this forum. Link to comment Share on other sites More sharing options...
10ring Posted December 10, 2009 Share Posted December 10, 2009 I load to 1.200" for the Limited gun. Link to comment Share on other sites More sharing options...
G-ManBart Posted December 10, 2009 Share Posted December 10, 2009 Just for the sake of testing I've gone as far out as 1.25" or 1.26" (can't recall which) in my 2011. Granted, not every chamber will likely accept them that long, but mine is totally fine with it and they still fit in the mags. I didn't notice any smoother feeding going out beyond 1.20" so that's what I've stuck with. Mine feeds factory ammo perfectly, but it's clearly not as smooth when you hand cycle it with them. I wouldn't go below 1.18" in a 2011 style gun as the shorter the round, the longer the jump is to hit the ramp and that simply gives it more opportunity to nose dive. I'd bet 90%+ of the folks running a 2011 in .40 are using something in the range of 1.18 to 1.20". R, Link to comment Share on other sites More sharing options...
AriM Posted December 10, 2009 Share Posted December 10, 2009 first, build one as long as your magazine will hold....then see if it stays under the hood in your specific bbl. , if you are really adventurous you could have your bbl. reamed and re-throated for that specific OAL...just keep it under industry MAX....there will be a different answer to this question for every load and every gun....do a little investigation on what fits YOUR SPECIFIC gun best....test , test, test and then when you are done re-test some more....keep meticulous records and save your targets....sooner or later the perfect balance will come to you Link to comment Share on other sites More sharing options...
boz1911 Posted December 10, 2009 Share Posted December 10, 2009 1.200...............easy number to remember and works well. Link to comment Share on other sites More sharing options...
Joe4d Posted December 10, 2009 Share Posted December 10, 2009 1.180, simply because thats the longest my Para and Singlestack will chamber and I dont wanna have multi ammo supplies. Link to comment Share on other sites More sharing options...

Paul Burtchell Posted December 10, 2009 Share Posted December 10, 2009 1.180 to 1.185 has always worked on my 2011's in 40 S&W. Link to comment Share on other sites More sharing options...
benny hill Posted December 10, 2009 Share Posted December 10, 2009 Setting up the feed ramp & better followers & springs & it will feed any lenght. Link to comment Share on other sites More sharing options...
bbbean Posted December 10, 2009 Share Posted December 10, 2009 When everything is running right, my SV with a Schuemann barrel will load a piece of empty brass. When everything is gunked up, springs are tired, and I haven't done the maintenance I should, 1.25 will still load, so I'm running 1.25. Link to comment Share on other sites More sharing options...
Pat Miles Posted December 10, 2009 Share Posted December 10, 2009 1.200" CYa, Pat Link to comment Share on other sites More sharing options...
CocoBolo Posted December 11, 2009 Share Posted December 11, 2009 I have to agree with Benny. Both of my STI Edge guns and my Infinity eat anything you feed it. From short to long with equal ease. I normally load 1.185 with Precison 185's with jacketed 200's 1.20. With 135gr down to 1.140. I shoot FN and JHP's with equal reliability 100%. I use dawson followers I found them to be the most reliable. The STI follower works ok in 9/38 but they do not feed a 40 reliably. The mag sping needs to lean to the right when viewed from the primer end. I don't use a 126mm mag because they won't fit in the gun correctly with the Dawson Ice mag well. I will assume you have tried factory ammo and more than one mag to try to narrow down the problem. A description of the jam and a picture would help nail down the problem. A Redding GRX eliminates a lot of jams that come from non ISO9002 reloading. When loading long you need to drop check bullets from both ends as they won't go all the way in the drop check so you flip them around stick them in backwards as well.

sargenv Posted December 11, 2009 Share Posted December 11, 2009 With the right kind of bullets, you can likely get length out to 1.240".. though lots of poeple use 1.200". I load my long RN's to 1.240" in my Para P16.. and I checked the magazine length of an S_I and it would take these long RN's. Link to comment Share on other sites More sharing options...
mildot1 Posted December 11, 2009 Share Posted December 11, 2009 1.190 in my STI, using standard STI springs and followers. I used to have a lot of hiccups using once fired brass till I use some that had been thru a roll size machine. Now I run everything theu a GR-X die and all the probs went away.

Two Delta Posted December 11, 2009 Share Posted December 11, 2009 I've never had a problem out of my stock Edge with factory ammo but I reload to 1.200. Link to comment Share on other sites More sharing options...
greyhoundman Posted December 11, 2009 Author Share Posted December 11, 2009 I went over to my buddy's place and did some tweeking to his case length, we loaded some at 1.185 and cant really go much longer with the LSWC and still seat the bullet deep enough to cover the lube. Also tightened up the crimp a little too. The ongoing problem we have been dealing with is the bullet (LSWC) will jam feeding in to the chamber, with the nose hitting the top of the chamber, case side stuck at the radius between the ramp and chamber (ramped barrel) and the rim of the case is still below the extractor. I know the extractor tension is not too tight, if anything it is on the loose side. His gun has had exactly one box of factory ammo through it a couple of weeks ago if memory serves it was Magtech jacketed flat nose and as I recall it fed well, again if memory serves the OAL was 1.125......He is going to blast a couple hundred off tomorrow......while I am at work.....and "give me a report" Link to comment Share on other sites More sharing options...
calishootr Posted December 11, 2009 Share Posted December 11, 2009 out of my limcat custom limited gun I am running either or, bear creek moly's and MG 180 gr CMJ's at 1.195ish buuut they are buth a trunicated style bullet the LSWC's might be part ofthe problem, as the sharp edge ofthe case is causeing the hang ups????

Jasonub Posted December 11, 2009 Share Posted December 11, 2009 im with benny here. i use svi followers trimmed down and ismi springs. Did the enos bend on the springs and it lasted for 2 or 3 years with weekly matches. Then the new bolen came out so i bought these and it was fine for 6 months. Jamming then occured, and i then remembered the enos bend and bent it. Is now 1 year and doing fine. Ill replace them after the year ends. I used to load 1.215 but was told to shorten it a bit since i was using a lot of powder. I went 1170 and no jams. 1160, still fine, 1135 and jams appeared once in awhile. Went 1150 and jams dissapeared. Tried 1140 and still reliable as a loose as a gooose 1911. Stayed with the 1140. Gun is an svi with a regular schuemann barrel. Ill replace the barrel with an aet this january. Link to comment Share on other sites More sharing options...
