I used some book data for the 338Fed and 210gr Sirocco Swift bullets. It was Starline brass, win mag primers and 45.5grs of Win 748 for 2441FPS and SD 4 in my short barrel rifle.
I also tested a 200gr Nosler BT bullet with same brass/primer and 50.5grs of Win 748 for 2592FPS and SD 1.
OAL for both was 2.280"
My question is how much more powder can I safely use for the 210gr Sirocco load?? I understand there is 10grs difference in bullet weight and also a difference in the jacket material (Swift bullet is bonded and 100% pure copper) but would like to safely get a bit more FPS with the Swift bullet. This is what I was thinking about for a Wisconsin Whitetail deer hunt.
Thanks for any help you can give me.
