What is the correct seating depth. I like to crimp into the cannelure, but on these you have two groves. With the top one it seems the bullet is seated very deep in the case. Advise please. I am using the 139g Hornady GMX.
PM sentI am looking at both 7x57 and 7x65R. For the 7x57 its perfect for 3.00" OAL if seated at the top cannelure, but in the 7x65 I am currently using the flat base Horady softpoint seated in the cannelure, but the GMX looks to be seated deeper. I am quite keen to keep to same seating depth so don't have to faff with adjusting things each time.
I use IMR4831 - 51.5g in the 7x65R
Haven't started working up a 7x57 load but erring on the side of IMR4350
As other posters have said, the OAL of your rifle is the most important consideration. I always set the depth of the seating to suit my rifle OAL (minus gap) and the crimp comes where it comes - irrespective of where the cannelure is. On my 6.5mm x 55 Mauser M03, the correct bullet seating results in the cannelure above the top of the case.What is the correct seating depth.

I am an old woman. But I've been a reloader for many decades, and have taught reloading professionally. If someone has such a problem adjusting the seating stem on their dies to the extent that they want to load all their bullets with the same setting, then maybe they are doing something that causes it to be more difficult for them than it should be. Maybe I could show him a couple of ways to change bullets, and then back with good accuracy -other than the obvious method of progressively seating the bullet deeper until you get the OAL you want.Muir you sound like an old woman ,leave him alone Heyme that is.
