    what is the consensus on best 300 blk mold

    Haven't been here in a while, but was wondering what are the better molds for 300 blk, i just got a new barrel and dies, (ar15). Barrel is an odin works 16" pistol gas 1-8 twist. what have you guys had the best luck with, hoping to get plane base 200ish grain bullet and i only use ww lead. I do have a lee 160 tl for ak but not sure if it works ok for this with feeding. suggestions?

    My favorite is the NOE K31 311-195 RF. The NOE version of the 311299 is also a good one. My only complaint about the K31 mold is that I bought the 2 cavity mold instead of 4 or 5 cavity.

    I would think "best mold" for 300BO would depend a lot on sub-sonic or full speed ammo? You mentioned the barrel length which also factors in.

    Cool

    “Best luck” for what? Accuracy? Function? Hunting? Subsonic or supersonic? Best looking? What is important to the OP, all we can do is guess….

    Through many threads, I have yet to see consensus. I like the Lee C312-155-2F.

    I to hi-tek these and they feed 100%. I shoot them over a little 2400 at about 1050 fps. It is super easy to shoot.
