I used my 6mm Comp Match last year for the local NRA High Power matches.
I did most of my fireforming with RL26, because I was just trying to use it up.....it's sooooo dirty.
All of this data is from a Krieger Medium Palma 1:7 twist - finished at 28in long. I believe that Dave Bruno cut the chamber with the 105gr Hybrid reamer. This leaves the 115gr DTAC's kissing the lands. I would like to seat the DTAC's out further, but with the accuracy that I'm getting I don't know why I would need to change.

Can easily be pushed faster, but this load is single digit SD's for me. I was using the powder measure on my Dillon 550 and still getting these low SD's. Sub MOA 10 shot groups.
Of course, please work up to any posted loads as they may not be safe in your rifle.
Good Luck.
