So, ELDMs, some Bergers, are quite jump sensitive. Some mess with .003 jump with them, I do .010 min jump changes.RE: seating depth. This is a huge revelation to me.
All Ive ever heard in this forum and any forum, from experienced Hammer loaders is Hammers are not sensitive to seating depth. Then all I ever read is how Hammers are different and throw everything you know about traditional bullets out the window. Members that question this, get shown to read a dozen stickie threads to confirm the why, with no simple explanations just go read.
A little frustrating as Ive left a tool off the table to fine tune my own Hammer handloads. I'll be experimenting with seating depth nodes for my group size now.
Hammers are jump insensitive (Not jump Proof) in that if they don't work good seated in the second valley, then it's the first. Sometimes, depending on the rifle, a Hammer will take a .120+ jump. The 308 WIN 137HH works best in my bolt gun in the second crimp with only .010-.015 jump. Most all the other Hammers are .040- .050 and under .075 jump, and seated in the first valley/groove.
