I can speak highly of the Normas 505 loads. I have used a fair amount in my CZ Safari Classic in that caliber, and it is by far the best of the current selection of commercial loading. As for Heym, I have a straight-pull repeater in 300WM that I use for longer range work that is built marvelously well and a 80B DR on order in 22 Hornet which will be scoped and regulated for 200yds. (Okay, I'm nuts.) I think the Heym will be an excellent choice. One question to olly however, "the Heym is a back up tool" in 505!!! What do you use for a primary weapon, a tactical nuke? Dave
