Round 2 update, reloaded some more rounds this week & here are the results. Have been using CCI-350 primers. Only partial sized cases, 1/2 length this time,rcbs carbide dies. Round 1 was full length resized. All shots fired at 100 yards again this week. I haven't cleaned the barrel bore since starting last week.
Here is a load copied from last week that had best grouping(last week), Med/Heavy roll crimp.
Next load using just enough taper crimp(rcbs) & IMR-4227 powder. All loads using IMR-4227 shot low.
Next 2 pic's with light roll crimp
Last 2 pic's with Hornady 265grFP, loads 2&3 were a little snug in chamber for some reason in first pic.
