I ran the testing floated, and with a small felt shim at the forend tip.
The scope is a Burris FFII, that I pulled from another gun. Short of something divine happening during the move from one gun to the other, it should be OK.
To be honest, I have a few reloading procedural suspects that I'm going to revisit, it's just that I want to minimize the amount of variables I'm going to be playing with. Hence, if one bullet seems to perform better on the average, I'd like to have that variable set aside. Likewise I forgot to shoot off bags and used my rest again, which has never worked out well for me with the H&R's.
I have a pound each of IMR's and H's 4350, and 4895 so hopefully one of those four should give me the goods.
