This load is very much at the upper end of the pressure envelope, but not to excess. It will positively make your 10" bb. scream! Best part of all is it's uniformity of ballistic performance. ES in the single digits in my tests!
No prob' contender, I don't know why I double posted. I shot a 250g and 280g in the 41mag, also. I got 1400fps with the 250, 1360 with the 265, and 1300 with the 280. The 265 wasn't marshall's, it was a cast performance. doug
