Looking for the correct barrel twist if I’m shooting 40-55 grain bullets. 22” barrel length. Thanks for the help

1-14" will stabilize any 40-55 grain bullet just fine.
Except copper.
At .22-250 velocities, I'd try it. Barnes recommends 1-12" for their 55 grain TSX, but it should stabilize at higher velocity. The 69 grain Matchkings that I shoot are supposed to have a 1-10", but work great in my 1-12". Now at .223 velocities I wouldn't push the twist recs as hard.
I tried it at max loads in a Ruger M77 and a Browning ABolt. The 55 gr. TTSX that actually hit the target went through sideways. The remaining got pulled.
The 45 gr. TTSX grouped like a 12 gauge.
Ok, I need to add that I am going to shoot lead free bullets since thats all I can shoot in Ca. The Remington action is getting a new Bartlein barrel. I'm not certain if lead free bullets will have an impact on what barrel twist I will need. Thanks for all the info guys, spending all this money to rebarrel this rifle I want to make sure I get the correct barrel.
