usmc1974 Posted June 27, 2018 Share Posted June 27, 2018 I can't seem to get my AR15 to run my reloads out the mag. but I will run the all day off my bobsled. The bolt seems to be stopping just short of home. Link to comment Share on other sites More sharing options...
Steve133 Posted June 27, 2018 Share Posted June 27, 2018 So, upon firing, it's ejecting the spent case, stripping the top round out of the magazine, and then the bolt's not going into battery afterwards? Link to comment Share on other sites More sharing options...
wgj3 Posted June 27, 2018 Share Posted June 27, 2018 Lube that sucker up to the point of dripping with liquid lube. Maybe add a little more action/buffer/recoil spring? Try different mags if you haven't already? Does it run from the mags with factory ammo? Does your reloaded ammo drop freely into a case gauge?

usmc1974 Posted June 27, 2018 Author Share Posted June 27, 2018 (edited) lol lube the sucker lol. my ammo runs in my other AR's. and I use small base dies from RCBS the buffer spring seem lite Edited June 29, 2018 by usmc1974 Link to comment Share on other sites More sharing options...
wgj3 Posted June 27, 2018 Share Posted June 27, 2018 Seems that the sb dies would fix most of those issues. Have you tried different mags and getting same result with all? Standard BCG? Or light weight? Link to comment Share on other sites More sharing options...
DesertTortoise Posted June 27, 2018 Share Posted June 27, 2018 Will it lock on an empty mag? If not, probably not getting enough gas to run the action Link to comment Share on other sites More sharing options...
usmc1974 Posted June 27, 2018 Author Share Posted June 27, 2018 It does lock open on last round, and it kick'em out at about 3 o'clock standard bolt will try other reloads and it runs on factory ammo it is a new 223 wylde carbine length barrel and gas tube.

DesertTortoise Posted June 28, 2018 Share Posted June 28, 2018 If it works when you cycle it (thru a magazine) by hand, then I'd look at your gas / buffer system If it doesn't work cycling by hand I'd look at your magazine, cartridge over all length, and chamber (in that order I think) Link to comment Share on other sites More sharing options...
rlillyskygod Posted June 28, 2018 Share Posted June 28, 2018 Case gauge the ammo first. Case gauge before you do anything else. Small base dies doesn't mean its right check it. Or spent a bunch of time and money changing things. CASE GAUGE. Link to comment Share on other sites More sharing options...

Tangowhiskey Posted June 28, 2018 Share Posted June 28, 2018 I have the Lyman case gauge/head space. 18$ if you search it. Cheap insurance to make sure you don’t have an out of spec round in the bunch. Did you trim the length and size your brass or is it factory rounds?

usmc1974 Posted June 28, 2018 Author Share Posted June 28, 2018 (edited) Factory ammo runs fine. I always trim to length, with rcbs 3 way. I will pick up a case gauge / head space Edited June 28, 2018 by usmc1974 Link to comment Share on other sites More sharing options...
Tangowhiskey Posted June 28, 2018 Share Posted June 28, 2018 I’ve noticed if I don’t lube the crap out of the brass when sizing I’ll get one in a hundred on a short stroke and just doesn’t make the head space. Sounds like what you had with the bolt not seating. But case gauge will catch it. Also learned a lesson on cleaning the case gauge, had grime in the gauge itself and thought I had a hundred bad rds that were good. Link to comment Share on other sites More sharing options...
usmc1974 Posted June 28, 2018 Author Share Posted June 28, 2018 I lube my cases light, because I was told and looked on YouTube to much lube can deform case mouth. Link to comment Share on other sites More sharing options...

Case gauging will tell you a lot as was mentioned. I have a JP gauge that sees every round. Link to comment Share on other sites More sharing options...
Tangowhiskey Posted June 29, 2018 Share Posted June 29, 2018 Looked on a lot of my casings and didn’t see any deformations but theory of too much lube would cause a lot uneven pressure. I use dillon lanolin lube and I let it sit for a min before running through press. I’ve had a stuck case in my die and it was a chore to get it out without damaging the die. Chore would also be an understatement.... that particular one got stuck like Excaliburs sword using case lube. Link to comment Share on other sites More sharing options...
usmc1974 Posted June 30, 2018 Author Share Posted June 30, 2018 (edited) Believe it or not, it was the buffer spring. It was harder to cycle then all my other AR's so I changed out the buffer spring with a new milspec one. Now it runs like a striped as ape, everything I feed it all my reloads WOW who would of thought I would not of..
