230 vs 244 grain 300 blackout

[aaholland]

I got one of my noe 330 grain molds smoothed out and removed the gas check for powder coating. The weight of the bullets went from 230 grain to 244 grain.

What kind of difference will this make? I know i will have to work up loads again but will it hurt how acurate it was at 230?

What other molds do you guys suggest for subs with smooth sides for powder coating?

Were you using the gas checks before? The best way to know is to get some made up and test them out.

No not using gas checks before. Awesome accuracy before the change. I will have to work up some loads with the new 244 grain. Just wanting to know what to expect.
