while waiting for replies, i went ahead and did load 10 with taper crimp & 10 with factory crimp. they all had 20.3 gr. of reloader 7 fed. lr primers. i dint notice much difference. the taper crimp edged out in group size dept.
i did notice that there seemed to be more pressure producded with factory crimp, and a slighty sharper report. again no leading & easy cleanup.
these were shot with iron factory sights, but i have filed down that fat bead in front to about .030 wide blade'
as aways thanks for the help, the info is working and i'am having lots of fun with this cast bullet thing! :grin:
