Don't get the Primos Truth Cam 46. It just dies after two seasons. Noisy when they take a picture. A friend bought one at the same time and they both died at about the same time. Piece of junk. Customer service told us they would not service them and would sell us a new one for the same price...
Always had great results with IMR 4350 and 150 - 180 gr bullets. Recently tried Rx17 and it worked great with 180 grain Sierras! Couldn't do much with it with 150's, though.
I tried it with my Ruger m77 30-06 with marginal success with 150's, but with 180's I was getting 1/2" groups. It seems to work better with the heavier 180's using 54 grains of the Rl 17..
