22gr with a 240gr pill will be a hot load, I have done this working up to 24gr/240 and killed many animals with this. It is hard on the brass and hard on the gun, but my Marlin 94s and ruger Black/Redhawk pistols have handled that load for around 50 years,(it will beat up S&W pistols quickly).
My Speer reloading manual recommends 22-24 grains as max with your 200 gr pill , says 21-23 grains on a 240.
These are +P hot loads to be used in well built weapons, I shot 10's of thousands of these in my pistols and rifles, I'd work up carefully in your particular situation.
I have never fired these loads in a Rossi rifle, nor would I start at any load considered max+ in any weapon. Good luck.
