Originally posted by hunthold: I would obtain a 400 to try out. Cut to 31 with the aluminum insert(16 grains) and your 190 grain head. The Gpi on the 400s are more and will help make up for the loss of the brass. My guess the 400 would be better for that poundage. Wouldn't hurt to by a single of each spine to test it out ..
