Broz, that's my thinking to 4 pairs or marks =4 groove. Can't imagine it being 8.

The only 8 groove I've heard of was Mossberg or Marlin?

Jeff, I see what you are saying however each one I counted was a bright band/indenture with two sides and dull non touched copper in-between each of the bright eight bands. It might be possible for the bullet to have bounced giving two sets of four, but they were equally spaced. I am not familiar with Kreigers build standards so I cannot say for sure. I do know it is a 1:10 twist.

I agree on the powder. I have checked several load sources and the max I found for a 300 Win Mag. was 79 grains. I plan on stepping back 2 gr. and going up in .3 gr. steps to do another ladder test looking for a better node for the Bergers. The best grouping I got from the range today was .040 off the lands so I think I will hold that and drop back to 76 gr. of H1000 and build up in .3 gr. increments to see if I can hit a node along that path. Houston is hot right now too.
Thanks Jeff.
