Nemesis Lead Posted August 8, 2016 Share Posted August 8, 2016 I have a bunch of long loaded 40 for a limited gun (1.195 OAL). I would like to shorten all my loaded rounds by .070 so that it will run in my single stack gun (1.125 OAL). Can I just re-seat the bullets and re-crimp them? Has anyone ever done this? Note--pressure is a non-issue. I shot a bunch of long loaded 40 and short loaded 40 with the same powder charge and there was (to my great surprise) no change in velocity. None.

kneelingatlas Posted August 8, 2016 Share Posted August 8, 2016 What's your crimp? If it's too deep it will swage the bullets as you seat them and you might lose accuracy. Link to comment Share on other sites More sharing options...
Nemesis Lead Posted August 8, 2016 Author Share Posted August 8, 2016 Thanks Kneeling. I just measured about a dozen. 8 were .420. Two were .419 and a two were .421. Link to comment Share on other sites More sharing options...
BritinUSA Posted August 8, 2016 Share Posted August 8, 2016 I would try it on a couple of rounds and then pull them and measure the bullet to make sure there is no deformation. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted August 8, 2016 Share Posted August 8, 2016 try it on a few rounds & pull them & measure the bullet to check for deformation. +1. And, I'd fire a dozen - check velocity and accuracy. Link to comment Share on other sites More sharing options...
BARRYJ Posted August 8, 2016 Share Posted August 8, 2016 If its lead bullets, it might shave a little lead off. No problem if it is jacketed ammo. Link to comment Share on other sites More sharing options...
Foxbat Posted August 8, 2016 Share Posted August 8, 2016 Correct, no issues with the typical jacketed bullet, provided they are not over-crimped. Link to comment Share on other sites More sharing options...
9supercomp Posted August 8, 2016 Share Posted August 8, 2016 Have you try running the 1.195" loads in the single stack, in my Cheely Custom single stack I'm running mine at 1.200" with Wilson mags and no problems. That way I can run the same load in my single stack and Limited gun. Link to comment Share on other sites More sharing options...
Nemesis Lead Posted August 8, 2016 Author Share Posted August 8, 2016 ETMs or 47Ds? 47Ds dont work for me. Link to comment Share on other sites More sharing options...
John Boy Posted August 22, 2016 Share Posted August 22, 2016 I just re-seated about 800 rounds of 9mm. Before and after accuracy test results were fine, I didn't chrony them. Acme 124gr RN bullets and Win 231 powder had to be pushed back .04". I'll use the rounds for practice. +1. And, I'd fire a dozen - check velocity and accuracy.
