I found two cans of IMR - Sr 7625 powder in a local shop for $10 a pound.By the burn charts it's in the Unique burn range.Any one tried it in the past?I thought it might be a 45 colt plinking powder.I don't think i have never seen any of this powder.$10 a pound I gotta buy it.

used did not like but if it was for plinking shoots lead
7.0 gr for 200gr lead

8.4 gr for 250gr lead

shoot good in my ruger 45 hunter both loads are below max

hope this helps
