300 Blackout Load Data

[Maryland_Shooter]

I was out test firing an AR yesterday afternoon at the public range. There was some cat shooting a non-NFA 300blk with a loud brake.

This guy was a strange BLK boy. He left his brass there... which I took for a member here who's shooting this caliber....

But when I asked him about going shorty, silenced, sub sonic, etc.... He was like... "that's too much paper work".

Struck me that he's missing any upside to the round by just shooting a full sized gun. AND not loading the round or saving his brass.

Newbie with money to burn? NFA. Is a PITA, but it's the only game in town.

I couldn't even fathom the notion that he was leaving the brass. Sometimes I'll ask for brass from people shooting .223 who look like they don't care about the brass... but a caliber like this?

The guy I build a 300 BLK upper for loads the ammo, so someone will get to use it.

I beg to difer with you. My Speer Hotcor 150 gr BT opened up very nicely all the way out to 200 yards.

I was talking specifically about the Nosler Ballistic Tip.

The 125 NBT was the toughest of the 125gr and 130gr tested, showing the least upset and deepest penetration. The 150gr NBT would probably upset less, or with a low enough velocity not at all.

I also see no good reason to use any 150gr for deer with the results of the lighter bullets.

That why I choose the Speer bullets- thinner jacket. I stopped using them in my '06 cause of that. Moved up to 180 gr Speers/SEI to stop blow ups! The NBT's are a thicker jacket though not the 125gr they are a varmit bullet in the '06. I going have try a find some of those 125 gr SEI's
