Used to be a go to for my 221 FB too.

Ps. Is that R17 or R7?

Is n120 like alliant rl7? That works around an even 20gn in 222.

I go up to 20.4 x N120 for 50, 52and 55 grain Berger bullets but best accuracy is at 19.
19 grains is only over max (Vhit data) with 50 grain bullets if using monolithic bullets.

Back to the original post… I use the same components as you but with 21.8gr n130. This is giving me 3250fps out of a 22” barrel.
