This is the only powder my buddy could get. He shoots barnes 180ttsx.

Barnes doesnt have data on this powder until their 190g bullet.

Nosler has data 72-75g for the 180g accubond.

Is it safe to start in that range.

Barnes 190 min max is 67-69.1g. Quite a bit different than the 180 nosler range.

Thanks.
 
It is not safe to use the 180 accubond data, solid copper vs lead core bullet. Hodgdon does have data for the 180 e-tip which would be a lot closer. Other option is Quickload or Gordons reloading tool.
