RL22 VS 4000MR in 30-06

[cypriss32]

I am building a 30-06 again. I used to use 60.0 grs of RL22 and never had any issues. I have read people complaining about temp sensitivity of Rl22 lately. I was wondering if anyone has used 4000MR is 30-06 and is it worth the change from RL22? The loads show about 100fps faster with 200gr loads.

I use 57grs 4000MR with 180 Hornadys, it does wonderfully with that load.
