I`m loading up some M855 62 grain tips with WC844, LC brass and CCI 450 primers. Should I crimp these?
Any advise on why to crimp or why not to. Thanks |

I do not crimp my 223.
However, I would except for my unusual way of loading gives me more than enough tension. When I size I remove the expander ball so the case neck is very tight. It is the seating of the bullet that expands the neck out for that tight fit. I do this for 55/62 FMJBT plinking ammo. My match ammo I slightly flare out the mouth with a couple turns of a deburring tool (To prevent copper shaving of match loads) Before if i did not crimp (and still used the expander ball) I had occasional bullet falling into the case in the magazine from recoil removing the expander ball or crimping insures this does not happen Wulfmann |

I put a light crimp on everything, its just good insurance against bullet setback. Just wondering how much crimp is considered a light crimp for say 223 and 308? a light crimp is about .001" or less smaller in diameter than the case neck. i just barely kiss my cases with the lee fcd I'm not even sure I'm doing anything in the process but it makes me feel better... just measured and its exactly .001" less than the case neck so i guess i"m doing it right lol |

In the past, Ive shot 7rds thru the same hole on a .223 with a vised rifle using mix,d brass. all cut to the same aol, and all crimp,d.
Ive gotten used to crimping everything..all of my load development is done with rds that are crimp.d. i recently tried rds with no crimp and what I noticed was a decrease in speed. which (for me) meant that id have to use more powder to get my patterns where they used to be...nice and tight....i decided not to add any powder and keep crimping. Its subjective...its your choice. less powder....less chance of possible set back on a semi.....uniform neck tension,,,especially using the same brand of brass |
