Have to seat to cannelure?

[SteelBanger]

Grabbed some 55gr Hornady SP and started loading up a ladder this afternoon and when seating to the normal 2.25 COAL for AR mags it leaves the cannelure about .06 (if I remember right) above the case neck. I feel like I've read that's no big deal but thought I'd double check here. No big deal or is there a legitimate reason to go ahead and push them down to the middle of the cannelure?

No big deal

No big deal

Cool that's what I figured, thank you!

There is a rule that says if you have a cannelure crimp at the cannelure. And then there is the rule that covers no cannelure.

I have a small machine that installes a cannelure meaning there is a benifit to having bullets without cannelure.

And then there is the company that said crimping could be a bad habit. I agree with the company that said crimping could loosen bullet hold; good news, I am the only reloader that uses bullet hold all the rest use tensions.

It makes no difference where the cannelure ends up if you are not going to crimp with a conventional roll crimp. If you try to use a roll crimp with the cannelure not in the proper place yes it can cause a bulge or loosen bullet tension. Solve the problem of cannelure alinement by getting a Lee Factory Crimp Die and you can put a crimp with bullet sitting anyplace you want. Nobody needs to start a bashing party of the Lee Factory Crimp Die. It works for me and I am just stating a fact as to how it is designed to work.

One other thing is I bought some "blemished" 55 gr soft points from Midway a while back. They were Hornady and the only problem with them was that the cannelure was positioned a little off from the first line bullets. The "blemished" shot just as good as the first line.

RT2506, I have Lee factory crimp dies, I do not use them but I have them JIC (just in case). And I had no ideal you were so sensitive about the equipment you use. I do not care what brand of die, press, shell holder or seating die you use. I do not make excuses for the tools I use.

Lyman said crimping could be a bad habit, Dillon said crimping and seating at the same time could be a bad habit. It was about that time they suggested I purchase all new dies from them. I made it clear if I had to start over with new dies I did not need their press. It was about that time they told me it would be OK to use their press with my dies.
