for rent , a lead mine

[powderburner]

just rambling:
I have been scrubbing on a 40-65 for about 2 weeks , I felt the need for speed and loaded the cases with 70 gns of 3F and a 265 gn pp bullet , in a 16 twist rifle ,
I got paper rings on every case ,
I dont know if I blew by or slipped the rifling , but they did get out and move, but they left a lot behind to remind me,
I did this once in the past with a 292 gn 45 pp bullet pushed with 110 gns of 2F for an express load, it didnt work either ,
I was wondering while cleaning how the old guys shot these loads , I suspect the twists were slower,
