ozdogg5 Posted April 14, 2012 Share Posted April 14, 2012 (edited) Howdy all, I'm fairly new to the site and this is my first discussion posting so please bear with me! So here's the rundown. I purchased a Glock 24 several years ago from another competitive shooter. It came with the factory barrel and a Storm Lake SS barrel. Since the day that I got it, I've been having serious problems with failure to feeds. At first, I thought that it was the SL barrel being too tight or the ramp needing to be polished for smoother feeding. After shooting a couple of matches with the stock barrel, it would still FTF about 10% of the time primarily with certain magazines (all have the +5 Dawson extensions). I ran a match this past weekend with the stock barrel and it performed 100% with only one magazine - the other three would FTF pretty consistently. Figuring that it must be the magazines, I purchased four new Glock mags with #6 followers, installed the Dawson extenders and took it to the range today. No luck, as it still FTF's about 10% of the time with ALL of the mags. Before swapping to new mags, the FTF's would just hang up on the ramp. After changing the mags, it looks like the bullets are slamming in to the left/bottom left of the chamber with the SL AND factory barrel. My question is, what could be the culprit? The extended mag springs are pretty new, the mags are brand new and the followers are new and supposedly the optimal ones to use. I'm also using a new stock glock guide rod. I'm guessing that it is maybe the OAL or HP bullet profile that is preventing it from feeding correctly. Maybe the Dawson extensions? Just looking for anyone that has experienced this and what course of action was taken? What strikes me as odd is how the bullet slams to the left of the chamber instead of being centered. Here is my load data: 180gr HP plated Rainier Ballistics with 4.3 Titegroup at 1.30 to 1.140 OAL. I've also attached a pic of the bullet getting stuck to the left of the chamber. Thanks in advance, guys. I know there is a plethora of knowledge on this forum and am hoping that y'all could lead me in the right direction. I've been wanting to get in to Limited division for quite some time but it sure isn't fun when you're malfunctioning several time per stage!

dskinsler83 Posted April 14, 2012 Share Posted April 14, 2012 1.135 should function great. Polish the feed ramp well and try a good round nose or truncated nose Link to comment Share on other sites More sharing options...
ozdogg5 Posted April 14, 2012 Author Share Posted April 14, 2012 Any trick to polishing the feed ramp or should I take it to a smith? I'd hate to mess it up and make it even more unreliable. Also, you're saying to leave the Hollow points and switch to RN? I never new HPs could be problematic since I've run several thousand through my G34 storm lake barrel. But if that's what I've gotta do.... I'm hoping others can chime in. Much thanks for the input! Link to comment Share on other sites More sharing options...
dskinsler83 Posted April 14, 2012 Share Posted April 14, 2012 The Hollow Points should be feeding. I just used a deemed with buffing wheel and red rouge and just polished the feed ramp keeping the tool at the angle of the ramp. I had a 24 with Lone Wolf barrel and if fed what ever I put in it and that was with a 14lb spring. But until u figure it out you have to change things to see what works.

ozdogg5 Posted April 14, 2012 Author Share Posted April 14, 2012 Did you Dremel the kkm or the factory barrel? I might just do that in the next couple of days. What COL were you loading to? Link to comment Share on other sites More sharing options...
ozdogg5 Posted April 14, 2012 Author Share Posted April 14, 2012 I've also got a glockworx extended steel guide rod with a 14lb spring but don't want to install it until I get these FTFs worked out. Any other suggestions? Link to comment Share on other sites More sharing options...
dskinsler83 Posted April 14, 2012 Share Posted April 14, 2012 1.135 and I polished both. You don't wanna remove material just smooth and polish is all. Link to comment Share on other sites More sharing options...
ozdogg5 Posted April 14, 2012 Author Share Posted April 14, 2012 I just checked the lengths of the bullets that misfed and most were between 1.14 and 1.145. One was extremely short (maybe shortened from FTF force) and one was at 1.135. I'm going to try shortening my loads tonight and trying them tomorrow at the range. What was your max/min deviation from 1.135? Also, about how long and what speed did you polish? I might just break out the Dremel and do that tonight also. Big thanks!

ozdogg5 Posted April 14, 2012 Author Share Posted April 14, 2012 Shoot, looks like I'll have to hold off on the polish since I don't have any compound. If I can't ind any red rouge, what other compound would you recommend? Link to comment Share on other sites More sharing options...
dskinsler83 Posted April 14, 2012 Share Posted April 14, 2012 It don't take long at all just a few seconds at a time. I stayed pretty close to 1.135 as I could. You can load out as long as ur mags will let you maybe 1.150 but u gotta make sure u got a good firm crimp and that they will drop in and out if the chamber. Use the barrel chamber as your case gauge. Link to comment Share on other sites More sharing options...
dskinsler83 Posted April 14, 2012 Share Posted April 14, 2012 Jewlers polish or flitz they sell polishing compounds at lowes u want fine stuff Link to comment Share on other sites More sharing options...
ozdogg5 Posted April 14, 2012 Author Share Posted April 14, 2012 Awesome. I may just have some jewelers polish so it may be a go for tonight. I've been case gauging with a Dillon gauge and my crimps are very light. The bullets feed when they go up the center but it puzzles me how they slam in to the left of the chamber. It just doesn't make sense to me... Link to comment Share on other sites More sharing options...
dskinsler83 Posted April 14, 2012 Share Posted April 14, 2012 Try a lil firmer crimp. Polish the feed ramp and the first inner edge of the chamber edges where the cases catch. Play with the over all length and again...USE THE BARREL CHAMBER to gauge ur ammo with lol the dillon case gauge doesn't go in the gun to shoot now does it lol hahaha. Go ahead and put the glockworks rod and spring in to might as well since that what u want it to work with Link to comment Share on other sites More sharing options...
shovel_doctor Posted April 16, 2012 Share Posted April 16, 2012 i had a similar problem with my glock 35. i was using the rainers 155gr and it would not run them. no matter what i did. i switched to x-treme 155gr bullets and they ran better. tightened up my crimp a little and i haven't had a ftf since, prob 1500 rounds. mine has a kkm barrel. i polish my feed ramps on everything i own,i do it the same way dskinsler83 described.never hurts.

ozdogg5 Posted April 16, 2012 Author Share Posted April 16, 2012 I didn't get to polish but I am making a few batches tonight o take to the range tomorrow. Batches @ 1.11, 1.125, 1.135 and 1.145. I'm also going to crimp them a little more. Any advice while I'm at the range tomorrow? Hopefully I find a batch that runs! Link to comment Share on other sites More sharing options...

I'm hoping it's not the bullet profile of the HPs. I've shot several thousand thru my G34 Storm Lake without issue. I really don't want to go back to RNFP - especially when i've got several thousand HPs on the shelf! Link to comment Share on other sites More sharing options...

tackdr1ver Posted April 16, 2012 Share Posted April 16, 2012 As others have said here before: Try and lightly polish your feed ramp with a felt wheel on your dremel using flitz or some other mild polish. What concerns me is the fact that you have all these different OAL's that you're measuring. That is something that needs to be addressed right away. Your pressures are going to be all over the map and of course your velocities will too. I run 1.135 OAL in my G35 without so much as a wince (I believe that 1.135 is SAAMI spec). So that length should work in yours just fine. I also run the dawson basepads and see no difference between stock mags and the mags with extensions. Currently I am running 180gr montana gold CMJ's with no issues. I have also run Ranier's 180 plated bullets with no feeding issues. The only issue I have experienced with the Raniers was keyholing and some core / jacket separation but that was my fault as I over crimped that batch. I crimp to .421-.420 anything more and it's too much and will rip the plating. Good luck! Link to comment Share on other sites More sharing options...
B_Seehawer Posted April 16, 2012 Share Posted April 16, 2012 Rainiers are a no go in both of my G24's. Pretty much feeds everything else but those. Brad Link to comment Share on other sites More sharing options...

ozdogg5 Posted April 16, 2012 Author Share Posted April 16, 2012 Be careful on those short loaded one that they don't go boom I know, I am quite hesitant but a buddy of mine assures me that he's ran many thousands thru his kkm and sl barrels because they weren't reliable above 1.12. Cross your fingers, in hopes that I'll keep mine! Link to comment Share on other sites More sharing options...

The only reason I'm loading different batches is to see what reliably feeds. Most of what was made is actually 1.13 to 1.135. Are you running an aftermarket barrel? Also, what profile MG bullets have you been running? Thanks again for all the input, fellas! I'm signed up for Limited at a couple of my first majors so I've it to get this gun runnin!...or else I'll be shooting a G34 in minor! Link to comment Share on other sites More sharing options...
Flexmoney Posted April 16, 2012 Share Posted April 16, 2012 That jam looks like the slide is not getting full travel. Something is likely slowing the slide or limiting it's travel. Here are some thoughts... It sounds like you have a good set of calipers? See if you OAL is staying consistent when pressed... - Measure a rounds OAL, then press the round into a bench with your thumb, with good pressure. Then measure the found again to see if it shortened. Also: - What recoil rod and spring are currently in the gun? You may be experiencing some of the old recoil spring bind. - How about your slide stop/release? Pull it out and re-install in, making sure to do it with the spring/pins in proper order. - Get your thumbs off the slide while you shoot. Link to comment Share on other sites More sharing options...
feederic Posted April 16, 2012 Share Posted April 16, 2012 Do you have a magwell on there? If so, make sure it is not overly tight which can deform the grip a little. Are you using stock mag springs with the Dawson followers? Have you tried normal factory mags? Link to comment Share on other sites More sharing options...
