375 Raptor.

Maker makes some cool bullets. I have 50 rounds of their 12ga overwatch ammo for my genesis arms gen12 that's showing up any day now. Looks like some serious $hit, copper monos that expand to 40mm lol

@Elv8DM hopefully 114 won't effect NFA items. If it doesn't you shouldn't have a problem ordering the SBD without the unconstitutional permit, but who knows yet!

Subsonic performance comparison using the heaviest/slipperiest bullets Hornady offers for the three cartridges. .375 suffers by bullet selection since it is mostly a dangerous game caliber. I agree with those intending to use the Raptor in supersonic loads.

Wow that's interesting. Thanks for the numbers. I've never been a fan of 300 BO because it's such a niche cartridge that i don't have a use for. It only makes sense in shorts barrels and suppressed with subsonics. If you want to run supers it seems to be faster to just swap your upper than to adjust your gas block, change out your upper and redial your optic. Nevertheless it's pretty cool to see the external ballistic characteristics of a super high BC sub sonic.

Hell yeah, the gen12 is badass. Do you know if there's anything different going on for the buffer and buffer spring in the lower?
