[QUOTE="rpierce, post: 1639297, member: 20643"] Well I did a powder charge test in the 300 norma improved with 8133 and 230 bergers .022 off the lands w cci 250 primers and lapua brass. Very promising so far. Several nodes. I cycled the bolt with one finger to better see when I got a bolt click. At 3025 fps it just barely got a faint click. There was a node at 3000 fps so I loaded 3 rounds up and shot them. ES of 10 and .240" @ 100. Loaded another 3 up and shot them at 400. There was a slight breeze but it held 1 1/4" vertical. Total of 10 shots to find that load. Not the fastest powder out there but it shot great with minimal testing. Even the 84 gr cupcake load at 2750 fps to get a velocity baseline with and foul the clean barrel shot a bughole. This barrel has about 600 rounds through it right now and is still driving tacks. Throat doesn't look bad at all. [/QUOTE]
