I loaded several different variations of powders, cases and seating depths, but never got a decent grouping with them. Tried 50 or so rounds on prarie dogs but never got a decent explosive kill shot. Everything was over 350 yards so I wasn't happy with this bullet, Can't give you a good loading, but I can save you some time. I used a savage 10flp and leupold 4.5-14 mildot scope. best group at 100 yds was 1.68. this is out of a half min angle rifle.
