mda Posted March 20, 2012 Share Posted March 20, 2012 Does the round fit following the seating operation before the crimp station? Try to find to operation/station that causes the bulge in the base since you say it fits once sized and deprimed. MDA Link to comment Share on other sites More sharing options...
40S&W Posted March 25, 2012 Share Posted March 25, 2012 You might be belling the case too much and when you are using the Lee FC Die you might not be fully resizing after the the crimp and leaving a slight buldge just above the extractor groove. Basically getting something like a glock 40 case buldge. Try just belling the case mouth enough to set the bullet without it falling out and make sure that the Lee FC die is going down to the extractor groove. Remember 9mm is a tapered case & 40 S&W is not. Buy a box of 9mm White box and try those, if those work then setup your dies to mimic the WB measurements. If it does not work, the after market barrel might have a tight chamber and a little reaming by a good gunsmith would aliviate your problem. White Box 115gr. 9mm FMJ At case mouth 0.3754 Just above extractor Groove 0.3856 OAL 1.158 on average Don't know who's bullets Winchester uses but it is a hollow base 0.3540 My reloads: At case mouth 0.3766 Just above extractor Groove 0.3860 OAL 1.143 Bullet is Berry Plated 115 gr FMJ 0.3550 Hope this helps you.

willfully armed Posted December 31, 2012 Share Posted December 31, 2012 get rid of the Lee sizer. I had the same issue with Lee sizing dies on my 650. Im now running a Hornady sizer with no issues Link to comment Share on other sites More sharing options...
DRichardson Posted December 31, 2012 Share Posted December 31, 2012 I'm wondering who the aftermarket barrel is made by. My storm lake in my open gun makes it all but impossible to load hollow points because the OAL gets way too short. Major is out of the questions till I get it reamed.

rhyrlik Posted January 1, 2013 Share Posted January 1, 2013 Some chambers shave short and tight freebores/throats. TC profile bullets require a shorter OAL because the sharp shoulder engages the rifling sooner. If you look at Hornady's data, you'll find they recommend a very short OAL for their XTP bullets. MG bullets have very similar dimensions. Link to comment Share on other sites More sharing options...
blue Posted January 3, 2013 Share Posted January 3, 2013 my xd 9 is at 1.075 any longer and it hits with factory barrel Link to comment Share on other sites More sharing options...
rooster Posted January 3, 2013 Share Posted January 3, 2013 try using a factory round, if it drops into the barrel with no issues then try to duplicate the factory measuements on your reloads. if the factory round will not fit the barrel then the barrel is suspect.
