Hey all, I posted about this particular rifle about a week ago concerning the crown. Took it out and ran 100 rounds through it. Shot pretty good, had one group at 0.25" - don't think the crown is an issue!

Anywho, the main purpose that that trip was to break in rifle and to get my brass set for neck sizing. Now I want to start doing some load dev to see what this babies got.

Book is 2.350 COAL, I'd like to stretch that out a bit. Tried the magic marker on a dummy round method and came up with the following COALs that leave the bullet off the lands:

40 Gr Hornady V-Max 2.480"
55 Gr Berger Match Grade 2.465"

Anyone who has this same rifle/caliber - what COALs are you using? Thanks.
