I run mine through the Lee factory crimp die.  Honestly, I haven't ever done any tests to see if it does anything, but it's just one more pull of the lever.

I crimp all hunting loads because of all the bouncing around.I have had bullets walk out and have difficulty chambering the extended round.never noticed any accuracy diff. when loading just to go to the range.

:Yeah:  I don't know if I've ever not crimped, except for dummy rounds.

I give my big-boomer revolver rounds (.44 mag, .45 Colt) a slight roll crimp.
I give my semi-auto handgun rounds a slight taper crimp.
My hunting rifle rounds don't get a crimp.  The long bearing-surface of the bullet keeps them
in place quite nicely.  I've never had one move.....even after being jostled around in my pack.

 :tup: could be a diff. from needing to be annealed and not that caused the bullet to move i guess but knowing that it wont when crimped is nice insurance.  :twocents:

I do it mainly for hunting rounds, because they go into the magazine, into the chamber, out of the chamber, out of the magazine, over and over, over the course of the season.  I also seal the primer pockets and necks, because they are out in the elements, over and over.

I have just started to neck size some of my hunting rounds, so I may give some the no crimp treatment and see if it makes a difference.

I go the other direction - anneal every round, low neck tension to get low speed variations but then I’ve never tested with crimping.

I am actually leaning towards doing exactly that.The .300 win mag loaded hot does a number on the brass in my opinion.

:chuckle:

IIRC, one of the selling points of the Lee neck sizing die was uniform neck tension.  I don't take accuracy efforts to the ludicrous levels with my hunting rounds (1" at 100 yards is acceptable for <400 yard rifle, for me).

I suspect I would not see much difference in accuracy over full-length sizing for these purposes, honestly, but I thought I would give it a go for informational purposes. 

I don't think your discussion is beyond the scope of the thread, so unless OP has objections, fire away. 

It's not as if most of us are going anywhere.

I anneal all of my brass every firing. Not sure its necessary but tue machine is sitting there so i may as well use it. Plus it helps dry my brass after i tumble it.  :chuckle:

I anneal every loading as well. Easier than keeping track of when I did it

I only crimp if its going into a semi-auto,  no reason for the rest of my firearms, single shot and bolts.   Don't have a tubular feed rifle but if I did, it would get a crimp.  I've had clip fed ones, no need to crimp them too.

I put a slight crimp on my 44mag wheel gun ammo.

Yes anneal every time just seems to tighten groups.    Trying to shoot 5” groups at 1000 yd so every bit helps.

Everything goes through a Lee Factory crimp die at my house.

Especially the higher power tubular magazine rifles.  But I just lee factory crimp everything.  Don't really need a cannelure with the Lee die.

I like the lee factory crimp dies.  I've never really noticed any accuracy difference between crimped or not, but it gives me the warm and fuzzies when it comes to hunting ammo knowing that nothing should move.  Some of the loads I use are pretty compressed.

in the meantime, i'll be cleaning my gun
