Hey everyone, I've had an impact m4 .35 for a few weeks now. I have it tuned currently to shoot 93 grain .357 NSA slugs at 900fps +/-. I was beginning to wonder if a higher than 875-880 fps was possible with a stock piece, and apparently it is. This comes out to a wicked 167 foot pounds. I know with this rifle being so new that there may not be a lot out there about it's true potential and user's experiences. It is truly a work of art when you have this thing to the sweet spots. Cheers everyone
