John,
Thanks for educating my regarding R16.
Would you be kind enough to do the same with regard to Ramshot HUNTER? I know nothing about it.
As always, thanking you,
Rick
Hunter is an excellent powder in the .270, with a burn-rate about like RL-19 but more temp-resistant. But with 150s Ramshot Magnum also works very well, and is even more temp-resistant than Hunter.
