SIGcurious Posted April 15, 2021 Share Posted April 15, 2021 For those shooting a 929 (or other 9mm revolver), what type of crimp are you using? If reloading on a Dillon, are you using the standard 9mm die? I normally load a FMJ bullet with a taper crimp, but I'm getting some coated lead bullets (never used before) and was just thinking if I should use a die that puts a profile crimp on it, but Dillon doesn't have an "Accu-crimp" die for 9mm. I'm probably over-thinking this ... thanks Link to comment Share on other sites More sharing options...
jcc7x7 Posted April 15, 2021 Share Posted April 15, 2021 Taper crimp .002 Shoot 7 rounds and measure the 8th. Make sure it's not creeping out. Ie getting longer Link to comment Share on other sites More sharing options...
MikeyScuba Posted April 15, 2021 Share Posted April 15, 2021 (edited) I use a Lee fcd. I just kept crimping until no more creep on rounds 7&8 honestly never measured it. There is an indentation on coated rounds but doesn’t affect accuracy Edited April 16, 2021 by MikeyScuba Link to comment Share on other sites More sharing options...

ltdmstr Posted April 16, 2021 Share Posted April 16, 2021 Keep in mind that if you cut through the bullet coating, you're going to get lead in the barrel. Particularly if you use a fast/hot powder. Link to comment Share on other sites More sharing options...
zzt Posted April 16, 2021 Share Posted April 16, 2021 My revo shooting SCSA buddies tell me they use a roll crimp to prevent the bullets from walking out. They DO NOT use NLG bullets. Link to comment Share on other sites More sharing options...
AzShooter Posted April 17, 2021 Share Posted April 17, 2021 I shoot .358 bullets in Winchester brass and have not had pull-out problems. I do not crimp because with my setup I've found accuracy to be improved with the .358s over a crimped 9. Link to comment Share on other sites More sharing options...

firewood Posted April 18, 2021 Share Posted April 18, 2021 I also use a U die (EGW), a Dillon 9mm crimp die, .358 coated bullets and Winchester brass. Link to comment Share on other sites More sharing options...
ysrracer Posted April 19, 2021 Share Posted April 19, 2021 I think Lee and EGW U dies are one in the same. Link to comment Share on other sites More sharing options...
SIGcurious Posted April 19, 2021 Author Share Posted April 19, 2021 What is the advantage of the U die when shooting revolver ... little to no crimp needed? Link to comment Share on other sites More sharing options...

It is case mouth tension that holds the bullet in an auto-loading cartridge. A U die gives more case mouth tension, add just enough taper crimp to remove the flair. Since going that route I haven't had a single instance of lose powder in the cylinder. Prior to that I had a few. Link to comment Share on other sites More sharing options...
