Looking at Accurate Molds BO mold and it is a plain base, no gas check.
Will soley be used subsonic, any reason to be concerned about lack of a gas check?

At those speeds, the only concern is proper hardness to obdurate. I use a Lee mold subsonic, no gas check. Never had any leading (PC'd).

Agree nothing to worry about. Keep speeds below 1300 fps and get by without checks just fine.
I have yet to get any plain based bullet to work in my 300 BO pistol.
If you're using a bolt gun you might have better luck.

got an NOE 247 GC mold that shoots great without the GC
Wellllllllll, if you end up getting a suppressor you will want a gas check to prevent filling the suppressor with lead. I’m not sure if powder coating will prevent lead in the baffles but I know from personal experience it will start building up lead with a quickness. I tried my NOE 311299 With an without gas checks and I didn’t notice any accuracy loss....just lead build up lol. If you don’t plan on using a suppressor then I would vote agains using subs in general, less fpe and less accurate in my own experience.

I have three 300 Blackout rifles. An AR side charger, a Ruger bolt and a Handi single shot. None of these are suppressed. I see no need for subsonic rounds in any of these nor do I see the need for a gas check up to about 1500 fps. Gp
I shoot the NOE 247 Plain Base in a suppressed bolt gun. No problems with leading, I didn't want to chance a gas check coming off in the can. I can almost guarantee any gas check designed bullet shot without the gas check will cause leading.

Thanks for the replies.
Should have mentioned it will be in a bolt gun.
Maybe this will be a good way to give powder coating a shot.
I use plain base in my AR at around 1200 to 1250 and have no problems. They are powder coated though and that may make a difference. Still working up an accuracy load but 1 1/2 inch at 50 yards is serviceable for me.

This is the mold I'm looking at, thoughts?
I run a Lee mold without GC, suppressed and non suppressed. No issues to speak of. As to lead in suppressors, if the powder coat prevents leading in the barrel, and prevents leading in the gas system, why would it not prevent it in a can? I guess we will find out, as I've been running a crap ton of PC pills through my sealed can.
nope and no worry about abdurating either. If the bullet is sized to your bore which means anything over .308 there is absolutely no need for it to bump up to fit anything. If that wasn't true you sure wouldn't get accuracy out of jacketed 308 bullets in a 30 cal ar. My guess is if anything like with about ANY gun that isn't a piece of crap harder will shoot better. Its why we are always chasing jacketed accuracy. Now if you don't want to use your good alloy or don't want to buy lino ect or just happen to have a bunch of soft lead its worth a try for bullets shot at that low pressure range. PC will at least allow you to do it without leading.
I have no issues with a plain base POWDER COATED BULLET PAST 2000 fps. This is from Various calibers and barrels. Just Keep pressures down!
