Home Forums Reloading Big Game Rifles 44mag on steriods, 445 supermag

Update week 3:
I have got brass primer pockets reamed/uniformed to accept LR primers. Have full length re-sized this week. Shot at a friends house today,100 yards again. Was hoping he had his Chronograph set-up now but he still needs to build a stand for it. I did wipe cloth thru bore twice before going to his house. All rounds had a Med/Heavy roll crimp. Didn't seem like light crimp worked too good for me last week.

These first 3 groups had about 10 minutes between groups. Shots were fired consecutively in each group about 1 minute apart. Had approx. 10mph crosswind. I didn't mark 1 shot in group C(right below lower marked C), I believe this shot took part of my A marking(on paper target) in that group out. Lowest shot of A group was first shot fired.



Friend got cold & went inside his house while I fired the next 12 rounds. He wasn't dressed for today's weather. He shot his rifle at another target in between my first 3 groups above. All shots were fired with about 1 minute between shots.

IMR-4227 groups:







Hornady 225grFT, I'm not sure which bullet holes are 34gr vs 34.5 gr.
