My two 300 WSM's (both T3's) shoot 180gr. TSX's into cloverleafs using Reloder 22, Fed. 215 Mag primers and Norma brass in a very compressed load.
I strive for compressed loads in all my handloads and RL22 with these 180gr. TSX's gets me exactly that. In fact, I use RL 22 also in my 25-06 and 270 WSM and couldn't be happier. I go with a bit slower RL 25 in my 300 RUM using 200gr. NP's. I tried, but couldn't find a powder that would get me a compressed load in that case.......it would take over 100grs.+.
