A chamber? What bullets and speed were you getting?

A chamber? What bullets and speed were you getting?

Sorry, I thought I replied to this via my phone yesterday - apparently not.

"A" chamber and I settled on 3030FPS with 175/180 bergers. The 175 load is published on the SS load pages on Sherman's website.

That is where I stopped development because it was more than enough velocity, accuracy/repeatability was there and I was out of time. Dies are all "A" chamber as well. The pile of brass I have is also pre "B" chamber adjustments but the website says the brass doesn't change for B chamber. Again sorry for the delay. I need to "tech" better.
