MorningSwoop Posted October 17, 2013 Share Posted October 17, 2013 Howdy, I'm having an occasional FTF issue where the round will get stuck going up the feed ramp, locking the slide back (slide stop isn't activating). I'm not nose diving, the round just gets caught on the ramp. I'm using tuned Brazo mags with grams guts and DP +1 SNL. Ammo is loaded to 1.200 OAL MG FMJ. The gun is a Brazo HPE with a FLGR & 12.5 ISMI spring. It happened only once or twice earlier, but more recently I've been getting 2-4 a match. Is it an extractor issue?

Noah my boy Posted October 17, 2013 Share Posted October 17, 2013 The extractor could be alittle tight. I found that my edge would FTF once in awhile and found that the round itself needed an extra crimp. My edge did not shoot factor with me running it through another crimp. Hope this helps.

MorningSwoop Posted October 17, 2013 Author Share Posted October 17, 2013 So would i just remove the extractor and start bending it out little by little? Link to comment Share on other sites More sharing options...
superdude Posted October 17, 2013 Share Posted October 17, 2013 It is unlikely to be the extractor. The round does not start to slide up the breech face and come under the extractor until after the nose of the bullet has started to enter the chamber.

Noah my boy Posted October 17, 2013 Share Posted October 17, 2013 Try the bullet crimp first. If you have to adjust the extractor the best way is to pull it out and flip it backwards back in the hole and bend it just slightly so the hook backs away from the breach face. It's not so easy describing this over tex. Link to comment Share on other sites More sharing options...
MorningSwoop Posted October 17, 2013 Author Share Posted October 17, 2013 I think i get what you mean with the extractor. Crimp would affect the way it bullet runs up the ramp? I use a Dillon 650 btw. Also I have polished the ramp before without much difference. Link to comment Share on other sites More sharing options...
Noah my boy Posted October 17, 2013 Share Posted October 17, 2013 Ya the rib on the bullet makes a big difference with feeding. It's worth a shoot to put alittle more crimp on your bullet. Link to comment Share on other sites More sharing options...
mumzer Posted October 17, 2013 Share Posted October 17, 2013 I had this issue with the oem extractor in my sti tactical. Tension was fine but it had ghastly radii on it. If you have another one in the spares kit, I'd give it a try. Link to comment Share on other sites More sharing options...
ParaGunner Posted October 17, 2013 Share Posted October 17, 2013 Try the extra crimp(fix bullet set back), if that don't work radius the extractor where the round slips under the it. Link to comment Share on other sites More sharing options...
GuildSF4 Posted October 17, 2013 Share Posted October 17, 2013 What is the OAL of your cartridges? Too short or too long can affect the feeding as you've described. Link to comment Share on other sites More sharing options...
SpankYa Posted October 17, 2013 Share Posted October 17, 2013 (edited) What is the OAL of your cartridges? Too short or too long can affect the feeding as you've described. +1 I load two different lengths: 1.130 for my Glock and 1.180 for my STI. My STI will fail to feed the shorter rounds 30% of the time. Edited October 17, 2013 by SpankYa Link to comment Share on other sites More sharing options...
MorningSwoop Posted October 17, 2013 Author Share Posted October 17, 2013 I mentioned OAL in the first post, 1.200. I've noticed this occurs more often on the 2nd to last bullet. Link to comment Share on other sites More sharing options...
kamikaze1a Posted October 17, 2013 Share Posted October 17, 2013 How fresh are your mag springs? Tension less with empty mag.. Maybe your springs sacked and can't keep up with the slide...only catching round partially when slide stripping from mag? Link to comment Share on other sites More sharing options...
GuildSF4 Posted October 18, 2013 Share Posted October 18, 2013 I mentioned OAL in the first post, 1.200. I've noticed this occurs more often on the 2nd to last bullet. Sorry missed that. 1.200 is a little too long for most .40 cal 2011's. Try around 1.160 to 1.180, this is the range that Brian's research found to be the best feeding. I run 1.180, 1.200 was causing the issue you describe in my edge. Link to comment Share on other sites More sharing options...
ParaGunner Posted October 18, 2013 Share Posted October 18, 2013 1.18 oal in the magic # for 40cal. Link to comment Share on other sites More sharing options...
broadus123 Posted October 20, 2013 Share Posted October 20, 2013 I never have any problems at 1.20. My sti will feed any oal I feed it. I would check the extractor. Link to comment Share on other sites More sharing options...
Biloxi23 Posted October 20, 2013 Share Posted October 20, 2013 I have been running at 1.210 and 1.200 with no feeding issues for a year and a halt, in three different 2011 pistols. Link to comment Share on other sites More sharing options...
TH3180 Posted October 21, 2013 Share Posted October 21, 2013 From what I have seen, best length is gun dependent. I did the same test Brian did and came up with 1.195" being the best for my gun. If I remember correctly, Brian found 1.175ish to be best for his gun. I don't think there is a magic coverall length. Link to comment Share on other sites More sharing options...
MorningSwoop Posted October 23, 2013 Author Share Posted October 23, 2013 I'm trying 1.18 now with my blank loads, it looks to be feeding a little more reliably but you can kind of replicate it if you let your slide forward slowly. I know the slide doesn't act like that in actual action, but its the easiest way to replicate the behavior. I don't think its the extractor as the bullet isn't even that far up yet.

Larry White Posted October 24, 2013 Share Posted October 24, 2013 Your mag lips could be a little too wide and releasing the cartridge a little too early.----------Larry Link to comment Share on other sites More sharing options...
Bob DuBois Posted October 24, 2013 Share Posted October 24, 2013 This is where the Lee U die will shine, seen it fix this issue several times. Can be purchased from Lee, EGW or Midway USA. Need to load ammo long. I like 1.220 using range brass my guns run. Lee's U die will size brass a little tighter than other brands and closer to the extractor groove. Don't care for Lee's locking nuts and on my 650 had to put the locking nut on the bottom of the tool head as the threads are shorter. Press may run a little slower as the die mouth is not as open and the press needs to be in time. Lubing cases will make the process easier. Crimp should be a few thousands under what the bullet measures in the case. The first stage sizing hold the bullet in the case. Crimp lets it feed into the chamber easier. To much crimp accuracy suffers. Most S-I pistols don't run well with stock length ammo. It's the U die or a push through die which is another step adding time to the process. Any feeding or extraction issues on a 1911/2011 check extractor tension first it is the heart beat of the pistol. Link to comment Share on other sites More sharing options...
