Heavy boolits for 300 BLK in AR

Wich heavy boolits for 300 BLK in AR. I plan to shoot it subsonic and coat it with Hi-Tek Supercoat. Does these flat points feed reliably in ARs?

Anyone with experience with these two? Se pics. Another recommendations? I need to get auto blocks for the boolits.

I only load for a semi-auto rifle and couldn’t get any flat point projectiles to feed properly, but I have no experience with the exact ones you mentioned.
If you are shooting a bolt gun, it might work well for you.
This is my favorite mold for my 300blackout. https://uploads.tapatalk-cdn.com/202...77b7089d2f.png

I use the 30/30 RD cast in mine, 185gr. No problem with Lancer mags. AR carbine. I don't run it sub though. More like 1400.

Here’s my experience with flat point boolits in the AR.

Look up Full Lead Taco on the interweb. He helped design the NOE 310-225-RN and has some videos on it. I can't help you much. I'm looking at a couple of hundred on them in a jar in front of me, cast and hi-tek coated. I haven't gotten around to stuffing them into brass yet. As I recall, they cast really well from that mold.

Ima, try Lancer mags. Magpull 223 have a lip at the front that makes the big meplat hang. Mag lips are also too long. Extension to feed ramp is another problem, sometimes there is a step that should be a ramp. Dremel fixes that.

That was using Lancer 300 BLK magazines. I really like the Lancers for cast boolits. No worries about the bore ride bodies causing stack binding. As for the feed… I solved that with a boolit more suitable to the task, the Lee C312-155-2R.
