Thread: 7 WSM or 7/300 WSM

I'm using Norma brass and necking down with a redding bushing die.
Velocity with 180gn bergers is 856m/s so not fast but accurate. I may be wrong but I think the longer neck helps hold the long projectile I have the base of projectile at the neck junction.
I shoots better than I can.
Got to run to squash, but throw some questions and I might be able to answer

Ouch. Is that common?
