Sakoluvr,
do you have a record of your muzzle velocities?
I've been loading the 225 PT, and none of my groups have been stellar.
I have loaded 4064, 4985 and have since "settled" on TAC since it gave the best velocities, but groups werent great with any of those. I'm using Mule Deers load data and mag primers with the TAC.
