Best lube subsonic AR rifle.

[Texaslawman]

Hey guys I will just be using the Lee resizer in my rockchucker press. NOE .311 247 boolits for a .300 blackout (subsonic) . What lube and method do y'all recommend so that these dont clog up my gas port? Also from all the reading, googeling, and searching Ive done it seems the lead from wheel weights will work just fine for my application. You guys ok with that? I have hundreds of pounds of the stuff Ive melted down.

thats quite a lot of questions to address in one post.
but your main question deals with lube.
since you will be using a push through i'll assume you'll be dip lubing or pain lubing these.
a soft lube will [by design] come off the boolit easier and faster than a hard one.
you might want to water drop your boolits even though they are subsonic.
finding a load that will be subsonic and still operate the rifle will be your biggest chore, the aa-1680 might just do it, but i'd also look at aa-2230 or 2400 on the slower and faster end to see what works.
in short just start somewhere and change one thing at a time.
