Damn it. Stop that.
You saw how good that cheap barrel shot, you're only a couple of hundred dollars away from 300 blackout bliss.

I have some 135gr hard cast bullets but im worried without a gc how hard i can push them.

I'd stay below 1200 FPS.

Even with hard cast? 18-20 BNH
They do not appear to be made for a gc no do i have the equipment to do it.

That's your call, I wouldn't go over 1200, but that's me.
Do you have a Lewis lead remover? Might not be a bad investment.

That would be about 1129 or less, that's why I said 1200, figured you could push it a little.

You don't think it will cycle the lighter ones?

If im going to run a sub i want as much mass as possible though they wont get much use.
110-125 will be for hunting.

I'm going to stick with my 125's for hunting, get it sighted in with them and if I load heavier I'll aim high for paper.

Im holding out that if i only get one thing in 15 im going to get a suppressor. Therefore the reason i want to run subs. But.... i will use this for bambi wacking as well most likely with 125sI'm going to stick with my 125's for hunting, get it sighted in with them and if I load heavier I'll aim high for paper.

If I ever go for a suppressor I'll just build another one, I've got a few extra lowers laying around here.

Mine is only a 10.5 so it will still be very compact!

Nice groups! 
I run lead bullets in my 300 Frankenrifle, 150 gn lee, either traditionally lubed or powder coated. If sorted after casting, from the bench I can keep 1 inch groups at 100 yards with no problem. I shoot these with either 16.7 of H110 or 16.5 of 4227. 4227 shoots more consistent groups.
Yesterday I tried two new loads using pulled Russian 150 gn bullets (I have had these for 10 years since I had a couple of bad batches of 7.62x54 ammo). One batch was boat tail and one was hollow base.
I used 16.5 gns of H110 on both and they fed, shot and extracted just fine. I had to load the boat tails short but it didn't seem to matter as they gave me a 1/2 inch clover leaf at 50 yards! The hollow base rounds grouped from 1 to two inches and seemed to not be made as well. They are all good for shooting paper though.

Did you run them through a .308 resizing die?
