Is anyone using BR5?

[Slow Hand]

I picked up a couple of jugs of BR5 from GIBrass.com last fall and finally got around to testing some out. Jeff says it’s a similar burn rate as Unique and ca;use the same data. I loaded some up in .32/20, .38 Special, and .45 colt along with an equal amount of unique. Chronograph showed the BR5 to be considerably slower and in the small amount of rounds I loaded, extremely position sensitive. I emailed Jeff about it and he said that since it’s a double based powder, it should be loaded to 80% load density. Well, I did some measuring tonight and there’s no way I’m loading to 80% in most of the cases I tried! I guess I’ll just load some cartridges up with ever increasing charges to see how close I can get to my unique velocities while still being safe.
I was just curious if any9ne here had any experience with this powder.

I have not used it. I'm running W244 right now. Supposed to have a burn rate similar to Unique also. It's a ball powder so the loading density is low. I like it so far. I've loaded 9mm, .45ACP, .38 Special so far and made a 12 gauge load up also.

Where did you pick that up at?

Ive got some test loads ready in .45 Colt. Hopping to get to the range today with my Chrono and get some data from a 4-5/8” Ruger Blackhawk and my 1894 Marlin. I was going to load up some increasing loads in 38 special but ran out of time…
