N133 Powder For 52 Grain 223’s?

[pirate ammo]

burn rate is too fast for that powder capacity

Thanks, I was using 42.5 of H380 at 3875 MV and it was damn good for me. Changing out me barrel to a Ramage with barrel nut. Stainless 28 in. 14 twist from Northland, so starting over. I really do not care because this thing is fun to shoot and when you take it to the range others drool.

I think any time you can use a VV powder over most all of the others is a good thing, provided its the right burn rate.
