Does anyone use this combination? I am going to load some up and would like to know if anyone here has a preference for the powder in this setup. Thanks

My first choice would be RL19 (69-71grs) followed very closely by RL22. With the lighter bullet a little faster powder works better for me.

it is a very good combo. i had good results with IRM 4831 and 4350 aswell as RL 19/22. there is just tiny pieces left when they hit a gopher.

did you guys chrono these loads? curious how fast the little bugger is traveling.......

I load this for a friend. I didn't keep all the info on the other loads only the one we load for his rifle. In a 24" MkX 70.2 grs of Rl19 gives 3470fps with a hornady 120gr fbsp. Group is about .65MOA. I have not tried it with the V-max but would think it would be in the same range.
