Anyone calling me here?
I am in Spain, and I'm from Spain, both are correct
. I know Maxam products and I use their Optima A, which is known as CSB-1 also, and as far as I know is to be used according to your Universal powder data, or so I've heard. It's a flake powder, medium burn rate. It could meter better, but with the Lee Auto Disk I get acceptable .1 variances. The load I'm using is 4.5 grains under a copper plated 125 grain TC bullet, HN brand. I get 1050 fps out of my SP01 Shadow. To get the same velocity, I need 4.7 grains in my Star 30M. Looser chamber, I guess, in the 30M. It's a single base powder. Quite versatile. Used for shotgun, 9 mm, .40 S&W, .45 ACP and even rifle reduced loads. I wouldn't call it "clean", though. It's cleaner than the French Vectan BA-9 (which is the only other alternative over here :banghead
, but it leaves quite a bit of gunk after a shooting session of, say, 300 rounds. It has a slower cousin called Optima R that can be used for stout 9 mm loads, or for the .38 Super to make major PF. Can't remember which "CSB" or "PSB" denomination corresponds to Optima R, though, but I'll look into it.
That CSB-5 is new to me, but it looks like it's a bit on the faster side, compared with the Optima A/CSB-1. A picture would be greatly appreciated.
Here is a pic I got from the net of Optima A/CSB-1. Tomorrow I'll snap one at my own powder so you can see what the current batches look like. If you get a good deal on any of these, I'd say go ahead.
