rjennings10 Posted July 27, 2010 Share Posted July 27, 2010 I purchased some Dardas cast bullets in 9mm 124 gr. (picture attached). I have to load them down to an OAL of 1.05 in order for them to feed and not get jammed up in the barrel. Does this OAL sound to short. I have not shot them yet because I was a little nervous about the pressure. If I make the OAL any longer the bullet will get stuck in the barrel. It seems like the barrel grooves start much sooner than I expected. Anyone else experienced this? If I need to explain anymore let me know. Thanks, Robert Link to comment Share on other sites More sharing options...

Thanks, Robert If you are worried about pressure, start low on charge and chrono and work your way up. I used to run some 125JHP Zeroes with 4.1 of N320 same length with no problems.

rjennings10 Posted July 28, 2010 Author Share Posted July 28, 2010 Thanks for the response. Since the OAL is this short I can fit more than 15 rounds in my 9mm magazines without having nose dive problems. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted July 28, 2010 Share Posted July 28, 2010 You didn't mention which powder you're using, or how much of it you're using. If you're loading with standard powders, at low rates, you should be fine (not compressing the powder) - but if you're using bulky powders or going "max" with the powder, you could get into some trouble very quickly, I think.
