I need some ideas on how to proceed. I cast a bunch of boolits for my .416 Ruger Alaskan. My boolits are gas checked 350 grainers from an NOE mould. The weight variation is quite low for a beginner. Boolits are water dropped and sized to .417. Using W-748 for powder, weighed each charge. I beat myself up shooting 25 of these beauties at the range. This load doesn't kick like jacketed bullet loads but it's no cup cake either. I didn't get anything you could call a group. Boolits landed everywhere except in the vicinity of each other. This rifle will shoot Swift A-frames into an inch and a half at 100 yards all day. Any ideas? I am an experienced shooter and handloader but new to casting.
Thanks,
