Surprised with the powder choices. I would think RL-33, Retumbo and maybe even US 869 might be better powders for this overbore chambering.
My 6mm-284 does very well with RL-33. Heavy 28" 5R bartlein 105 Berger hybrid 3535 fps.
Anyone ever try the slower powders?
We have been trying some vitavouri N 570.
Seems to work ok. Didn't see much difference in velocity compared to R 25.
The N570 is not all the great of a powder to use on a 22 caliber neck as it is so coarse and big.
