    Need mould for 300 BLK subsonic suppressed

    I'm looking for a mould for my 16" AR15 carbine in 300 BLK that is going to wear a Sig SRD762TI suppressor shooting subsonic loads. Any opinions on the NOE 311-220-FN Blackout mould? Is the GC a good idea with the suppressor? I was also wondering if the HI-TEK coating will be effective on this grooved boolit or if I should consider a slick-sided boolit (Accurate Arms)? I'm new to 300 BLK and to suppressors and wanted to ask for advice. Thanks.

    If you're going subsonic you won't need a gas check. Plain base is all that's necessary and it saves the worry of gas checks coming adrift and damaging/lodging in the can.

    Good point Fred: especially since my suppressor is welded together and a stuck GC would be a problem.

    I am liking the Lyman 311299 or 311334 bullets.
    They shoot well, and have body length to fit into the neck of
    the 300 BO
    Load w/o gas check for subsonic use.

    I'd be inclined to try the plain based 311299 (202 grain RN). It's a proven accuracy bullet and it looks like you could get both lube grooves into the neck with only minimal bullet base being down past it.

    The 180 grain Ranch Dog flat point tumble luber could be a winner as well.

    CHECK WITH SIG TO MAKE SURE LEAD IS OK THROUGH THE CAN!
    Many manufacturers recommend AGAINST using lead. I have crudded up more than one suppressor with lead and excess lube.

    I shoot lead through my can. Never a trace in it. Shooting 220 grain Leatherheads, PC'd.

    I had a NOE mold in the 230ish weight that was a great sub bullet. Had a good point that gave reliable feeding. Had to seat them a little deep but no issue. Only reason I got rid of it was not gonna do subs till cans are easy to get.

    Depends on what you are using it for but I do have the Accurate Molds 245gr fp, it works very well and feeds ok in all of our uppers.

    Use powder coat or Hitek, not lubed lead.

    Remember, all common bullets are lead bullets. It's what's outside the lead that makes a difference... So a powder coating gives you a jacketed bullet, albeit a thin jacket...
