Thanks for all the help fellas.
I think it is time to try a slower powder, the 4350 class powders don't seem to agree with my rifle/bullet combo.

Is IMR4831 temp sensitive? I don't know why but I prefer IMR to H. It seems to use a little less powder for similar performance.
I am hoping to avoid heavily compressed loads.
Keep the info coming, I am interested in what works for you with 225 grain projectiles.
