I have been using Re10x in my 204 and found it a very good powder with high velocities out of a short barrel. Easy on brass. Now Reloader is like rocking horse crap to get hold of and am looking at changing.

Any ideas, what are you using, want to keep the velocity up with 32 grain v max.

I am using R10X (I just got the last tub my shop has) try also H335, you should be able to get it easier, when my 10X is done this is what ill be using as my local doesent know when he will get more, also I heard vit 133 works well but have no personal experience with it so you may need to look into that one.
