Range day data mostly with Lever and the Sierra 85 bthp.
Test number 2 is I took some Factory Hornday black at 2.200 and tested five against five at 2.250 that I uses the bullet puller on to lengthen them.
Test number 3 testing 108 ELDM with Lever to see if I could find the max for my rifle.
All brass showed little signs of over pressure, a few had light ejector swipe but others with more powder did not show any signs.
Primers looked good except the CCI 400's. The Remington 7 1/2 at the higher powder charges there wasn't primer cratering but the depth of the indention from the firing pin looked like it getting deeper or the primer was stretching.
Question: What is your max loading for 105-108 bullets and Lever?
