I'm sure this has been gone over before but anybody using 10x in 204. Also what comparitive data are you using for starting loads?

Alliant says it is the same as H322 and can be switched. I would not write this stuff if the facotry rep did not tell me. Call and double check it worked ok in my 20-222. I used that as a base line and worked up. Call them, start low be careful. I could have talked to a janitor with a sick sense of humor and got lucky.

32gr. BK C.O.A.L. 2.250"

RE-10X start-22.8grs. MAX- 26.3grs @4000fps.

39gr.BK Start-21.6grs. MAX-25.1grs.@3700fps.

Benchmark is both the "Accuracy Load" and "Hunting Load" for the 32 gr. BK 27.3grs and 27.9grs. Respectively.

RE10x is the "Hunting Load" for the 39BK @25.1grs. @3700fps.
