.300 whisper crimp die?

Oops Kurtz you slipped in there before I could finish typing. Dunno what to say. I just set a 180 gr round nose (which really rides tight in the feed ramps) .220" in to a sized piece of brass and maually fed it from the magazine and it unseated .008". The brass was from Davis which has .004" neck tension so once again I know the bullet will move. One other difference is whether your chamber is tight or not. My 300 fireball chambers freely with the shoulder stopping the case movement not the body.

when I was working on the ramp I would feed the rounds from the magazine dropping the bolt with the bolt release....I'm using Hornady dies and .223 brass and end up with the same as you .004 neck tension, unless using Hawk and one other bullet that I can't think of the name..I end up with .005 neck tension with those....never had any move chambering....I probably get a little carried away realoading, nitrile gloves, de-oil bullets, one tumble to polish brass..another tumble to de-oil brass.....OCD

I use a 30 carbine Lee crimp die with a 3/8 fender washer sitting around the bullet. Took my calipers and went to H--- D--- and miked a few different thicknesses. I can put my crimp any place I like.
I even drilled a 1/8 hole at opposite edges and suspended it next to the die so to be out of the way. WORKS GREAT FOR ME

Fox out!

I got my M1 carbine die and started crimping the cartridges I loaded already. I didn't see a large crimp band. If what I saw was the crimp band it was only a milimeter thick. I trim cases to 1.34" is this why or am I doing something wrong?
I tighten the crimp die to the shell holder and then about 3/4 of a turn or so more. Seems to work fine.
