  1. Magazines will be this things issue… if someone like magpul makes mags just for the caliber I’m in!!! I have always been on the fence about .300blk and not a fan of 8.6blk, this however is what I wanted .300blk to be, but it’s really 7.62×39 American lol. Both of the other two have a better super sonic game than sub… this is the other way around.

    It can go super sonic and 175gr at 1900fps isn’t nothing… I think around 1450ft/lb? Which is more than 55gr 5.56 from a 20” barrel…

    But its sub sonic game is on point! And the biggest deal is sub sonic pressures on the high 30k range and supers only 15k or so higher makes it much easier to run subs and supers off the gas port without an adjustable gas block…
