chopps Posted September 3, 2014 Share Posted September 3, 2014 Looking for some suggestions or what some of you all are crimping a .224 69 gr hpbt bullet at ? I found all the other info I need but that spec escapes me. Just want some info to start with thanks for the help considering I have never loaded rifle cartridges before and just loaded pistol till now. Time to graduate.

rboyes Posted September 4, 2014 Share Posted September 4, 2014 No need to crimp. The neck tension is all you need to hold the bullet in place; if it doesn't then the neck is probably not being properly sized. Link to comment Share on other sites More sharing options...
Tom Freeman Posted September 4, 2014 Share Posted September 4, 2014 Crimping is not needed. Done right crimping wont hurt accuracy. Done even slightly wrong it destroys accuracy. Link to comment Share on other sites More sharing options...

MarkCO Posted September 4, 2014 Share Posted September 4, 2014 BUT, check the case neck tension to make sure that you are getting proper resizing, not belling the mouth too far etc. I have known of a few guys blowing cases and primers...turns out that they were deep seating bullets upon chambering. I use a Lee FCD on the 55 fmjs, just a touch, for some insurance. Link to comment Share on other sites More sharing options...
dauntedfuture Posted September 5, 2014 Share Posted September 5, 2014 Putting a crimp into a bullet with a crimp grove is much less likely to hurt accuracy as there is already a notch in there. A crimp into a bullet w. a crimp grove will increase pressure ever so slightly and possibly save bullet set back IF you slam a loaded round into a case stuck in the chamber, preventing a rifle full of powder. Crimping into a matchking bullet WITHOUT a crimp grove is another story as match bullets have much thinner jackets. Crimping into an otherwise good bullet will hurt accuracy and BC and there is no reason to do it that I can think of unless you are shooting lead bullets. If your bullets are getting seated deeper when they are going into the chamber crimp will not help; whats happening is the throat is too short and its setting the bullet back or you have some alignment or ammo length issue that's causing the bullet to bang into the feed ramps or barrel on the way into the chamber. If rounds are loaded too long they can also hang up on the front of the magazine, tip down and the bolt carrier will press the bullet tip into the magazine and the bullet into the case.

Tom Freeman Posted September 6, 2014 Share Posted September 6, 2014 Can you advise what wrong is? Too much. You can play with it a little bit. Add a touch of crimp until accuracy drops off. Even through my M-16 my ammo is the same. No crimp. My Dillon and Redding dies give me plenty of neck tension. Link to comment Share on other sites More sharing options...
