Hey, another voice to the chorus. I picked up a pound of it as well after reading Blue Press. I had looked at buying it before, but I had a bunch of WW231 already.
So far, I've tried it in .45 ACP and .357 Magnum. The .45 was with both 200 and 230 grain bullets, the .357 with 125 HPs.
I think I'm going to like this stuff. Seems to burn cleanly; they are right on the can about a little going a long way. My usual load with 200 grain SWCs in .45 ACP is 5.2 grains of WW231. I tried 5.0 grains of Titegroup and got a lot more velocity than the load I'd been shooting. Also, 4.5 grains Titegroup with a 230 lead RN shot well, seemed to be a good equivalent for 230 hardball.
In .357, the 125s got downrange in a hurry. Nothing like a full power charge of WW296, but still moving along. Probably in the 1300 fps range out of a 4" barrel. Very accurate - might take the title of my favorite .357 practice load.
It's going to take more fooling around with the stuff before I really make up my mind about it, but so far so good.
