FX Fx impact m4 800mm extended barrel potential....

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
 
I can’t wait until after Christmas so I can order my new M4 long fellow, .35. It’s going to be epic!
Hey man, if you add in the Huma v2 power upgrades and their regulator, that gun has true knock down potential. I honestly think it would go straight through a deer's skull at 50+ yards but have not tested theory. And after you add those upgrades, say you slap on a .30 cal barrel, the slugs are almost going supersonic speeds.....

Ok, I’ll note that. I’m planning to go with a Western Rattler .457 for the deer hunting, and an MCAR .457 for reach out and ding ‘em. I’ve been looking for the MCAR in the .510 Hunter configuration but can’t find one. Any thoughts?? Thanks.
