Thus far we've mostly been shooting the 39 gr Sierra from the 204. Results have been excellent. But, we are expecting delivery of a new barrel soon, so that the other 204 can be made up, and it has a slightly faster twist than this current rifle. The intention with the new rifle is for it to shoot the 39/40/45 gr bullets, and to move the current rifle down to the 32s.
Right now I have available:
32 gr Sierra BK
32 gr Hornady Vmax
39 gr Sierra BK
40 gr Hornady Vmax
40 gr Nosler BT.
I intend doing some bullet testing next time I get near the range. Most likely I 'll just use 2206H for the 39/40 gr stuff, and probably BM2 and 2206 for the 32s. I've got enough 2206 to last for a while if that turns out to be the best powder.
Be curious to hear what sort of results (accuracy and velocity) others have had with this range of bullets.
