Howdy fellas, Please excuse me for bringing it up again.....
but I still can't seem to get this crimping thing correct...
for what ever reason, my Lee 45/70 factory crimp is
working great. I have no clue what I did differently but
the last two batches I made with 350 grn hornady's appear
textbook right, shoot great too !!!

this evening I was making up some 30-30 loads, I crimped them
or at least was attempting to. the case mouth is still not crimping
around the bullet grove (channelure) I examined the Lee factory
die closely, it appears the bullet isn't going all the way up into the
die, the top of the case doesn't appear to reach the "crimping Jaw"
for lack of a better word. I took the die out to examine it and noticed
there is more than an 1/8th inch of play in the crimping sleeve.

I took out my 45/70 die to compare the two .. the 45/70 die does
not move, it is solid. Could lee have sent me a bad die. or perhaps
when I was in the learning process I screwed it up? Just to be sure
after I write this I'm gonna look into midway about ordering another
die. Please help me!!!! my poor kid is shooting lousy groups with
his Marlin 336 and I am convinced its his old man screwing up the
ammo, the season starts in two months, Thanks for your help!!!

Sometimes you have to take Lee dies apart and smooth them up a bit. You have to adjust your die body up or down to make sure the canelure is at the right place when the collet tries to crimp the case neck. And a little grease on the part the collets ride on would help too. If you email Lee, they will help also. BM

PS: Your Lee die will put a different looking crimp on your bullet than some factory loads.

if it is a factory crimp die it will not roll the case into the cannalure. you need to use your bullet seating die for this. The factory crimp die tapers the case into the bullet, if you use the bullet seating die it will give you a nice roll crimp into the cannalure.

Everybody has thier opinion, but if there is a cannalure on the bullet I like a nice roll crimp, as opposed to the factory crimp.

To set up the roll crimp get the bullet height you want, then unscrew to bullet seater all the way up and with the ram up screw the die down until is touches the top of the case. Lower the ram and screw it down another 1/2 turn. Raise the ram and check the roll crimp. If you want more try another 1/4 turn. After you have it set raise the ram again and with tha same round in place that had the proper bullet seating height screw the bullet seating adjuster down until it touches the top of the bullet. Load your next round and it should seat the bullet and crimp it in the same step. BUT CHECK YOUR OAL!!! YOU MAY NEED TO PLAY WITH IT A LITTLE. I have found that I usually am just a little long with the first round after I do this. If you want more info go to.

They have a section that explaines this better than me.
