saibot Posted January 26, 2011 Share Posted January 26, 2011 A friend and I buy all of our reloading equipment and consumables on bulk to reduce the cost as well as pool labor for reloading which in the past has worked just fine. I typically load for my M&P FS9 since it has a shorter barrel and we use it as the minimum which works out well for the XDM. Until now. I switched to Montana Gold 124 FMJ bullets, found a good charge and seating depth and pressed out a couple thousand of them like usual. They run great in my M&P and they do run in the XDM, but once chambered in the XDM you can not rack the slide to unload and show clear. You have to really muscle it open because the combination of the MG FMJ and the seating depth cause the bullet to engage the lands and get a bite on the bullet. The was never a problem before because the Zeros are more round where as the MGs strait with a single angle to the end. Bummer. So after all of that I have two questions. 1. As a sanity check, what bullet seating depth have you found to work with a XDM and MG FMJ? 2. He has 1k rounds he can't use until he bumps the bullet back. But I have crimped them with a Lee Factory Crimp Die. Any problems seating again with a crimped cartridge? Thanks! Link to comment Share on other sites More sharing options...

saibot Posted January 26, 2011 Author Share Posted January 26, 2011 I use 147gr with a oal of 1.124 on average sdm74 That's fairly deep for that bullet. Does it crunch when you seat it? Thanks for the info!! Link to comment Share on other sites More sharing options...

Red Ryder Posted January 27, 2011 Share Posted January 27, 2011 I use MG 147 and seat them to 1.120 with no problems in my XDM. I will get back to you with "show clear" tests. Hodgeson's does recommend 1.100. Link to comment Share on other sites More sharing options...
DougCarden Posted January 27, 2011 Share Posted January 27, 2011 Another possibility is to send the barrel to Canyon Creek, or Spring Precision, or any smith that has a chamber/leade reamer and have them set the barrel up for that combo. Should take a week or so, unless you have some one local that can do it for you. It is not that big a deal. Good luck, DougC Link to comment Share on other sites More sharing options...
