62gr oal advice

[James Shabnow]

I have a couple k of the hornady 62gr lead core .224 that are sold here. I’m loading them for the Ar platform to use as a range/training round. I’ve been doing a lot of reading and 90% of the info tells me yo load at 2.250″. That doesn’t seem to put me in them cannelure. Have any of you shorten them? It seems like I have to put a decent crimp on them to keep the bullet from moving when testing them againts the press frame.

I load all my .223 to 2.258, in order to stay under the 2.26 max overall length, as listed in the Lyman 5th. That works well in my ars so I have been able to stick with it. I have never had any issue reaching the cannelure or loose bullets, with 55gr or 62gr from rmr. I only crimp lightly. I never shorten a bullet length, without starting my loads at the suggested minimum and working up using the chronagraph, verifying ft/sec, so I don’t go over on case pressure. How tight is the bullet seated before crimping?
