has anyone used rl10 in the 221 fireball(rem classic)? any thoughts? tia, dh

It might be a bit slow for the lighter (<50gr) bullets, as you can hardly get enough RL7 in a Fireball case under those bullets. If I had some, I would try it, but if you are shopping, then RL7 is a great choice. Don't forget LilGun and AA1680 are also excellent for the 40-50 gr pills.

have the powders mentioned and also the rl10. always looking for something to try, that's why asking about the rl10. thanks, adh
