Anyone use these before. I'm running out of 220gr SMK's and need to find an alternative for my 300BLK subs. Gallant offers a 217gr Poly-coated pointed boat-tail. Most of the poly options I've seen are round or flat nosed with flat-base: not very accurate at 100yds compared to the SMK's.

I ordered some 200gr plated bullets from Berry's but haven't loaded them up yet:

They are almost twice the price of the Gallant though.

I'm a bit leery about shooting coated bullets through my rifle can. The 9mm coated bullets I'm using are leaving a lot of lead in my pistol can. Once I use them up I'm going back to jacketed.

Are you crimping too much, or are your bullets too small for the bore? If you bought them sized to .355", they are likely a bit too small. If they're sized right for your barrel and you aren't crimping very much (really only need to just remove the case flare) they shouldn't leave any significant amount of lead in your barrel or the suppressor.

Of course that's assuming it's a good tough powder coating. Not all coatings are equal.

You can't go too far wrong for that price. Please let us know what you think of them.

I've loaded a bunch of the 240-grain (actually closer to 245) Leatherhead bullets. They have functioned well in my 300BLK SBR, but accuracy hasn't been anything special:
http://leatherheadbullets.com/everything-300-blackout/
^ I have a sample pack of their 220-grain bullets too, but I haven't loaded them yet.

I have a bunch of the 203-grain Palmetto Projectiles bullets too:

I haven't loaded them for 300BLK yet, but I've tried them in other stuff like 7.62x39.

I've messed around with everything and yes I'm just barely crimping them. The bullets are .356"

I'll still use them for non suppressed shooting but the OP mentioned subsonic and I assume is using a can.

Bummer. What brand are the coated bullets you're using that deposit lead in the can? Are they coated with a polyester powder coat, or is it HiTek coating?
I'll admit that I haven't had great results with HiTek coated bullets and suppressors, although some guys love them. I coat my own with polyester powder coating, and the recovered bullets typically still have no exposed lead after firing, and my suppressors are just carbon fouled unless I'm experimenting with something that didn't go right.

I'm not sure who made them or what kind of coating they have on them. They're green.

I'll ask the guy I got them from.

Ran load development last weekend and settled on 9.7grs IMR 4227. Group size was about 1-inch at 50yds. Granted I was shooting with the thermal and getting a consistent sight picture was tough even on a 3" Target; it wasn't generating enough of a temperature difference between the paper and the target sticky. 220gr SMK are 1-1/2" to 2" at 100yds.

Polymer coating is fairly thin. Had to put a heavy chamfer to reduce/eliminate shaving the jacket on the mouth of the case when seating the bullet.

Do they actually measure at 0.308” or are they larger?

You should be belling/flaring the case mouth for seating any lead bullet.

I measured 10 and got between 0.307" to 0.309"

I load coated lead bullets for 300BLK that are 0.311". I flare the cases with a Lee universal expander, and then I use a Lee factory crimp die to close them back up.

I like that Lee universal flaring die too for single stage loading. Most of my 300 Blk loading is done on the Dillon though, where I use a 30 Carbine powder funnel which flares the cases.

Sounds like some of those bullets are really too small. For a powder coated bullet in a .308" bore, I want them to be at least .309" diameter at the base, and my chamber will handle up to .312" with no issues. .307" is definitely too small, without question, and is likely to result in some gas cutting and lead in your suppressor. That's disappointing.
