I use it in the M27, load to the old .38/44 specs. I dry brush the .357Mag chambers immediately after shooting.Nice looking bullets. I like the 358429 myself, though it's too long for most of the guns I've tried it in.
Just like any part of a loading. Change any part & results will change.Are you powder coating these. ??
I still am not sold on the powder coating. I have tried it in my 357. From what I see at 25 yards,the lube is more accurate..johnny
