On another site I'm reading a thread that one guy who shoots ipda is talking about powders. He said bullseye & tight group are cleaner than universal.

It's been a while but I remember it being the opposite ...
Y'all clear me up some plz.

I’ve used all 3 of those over the years, nothing against Bullseye, but use Titegroup now for that burn speed.

Universal is a bit slower, more a ‘mid-range’ handgun powder.

I’d say also individual powders can be made to be cleaner or ‘dirtier’ with different pressure levels. So maybe some of it depends, I do like both Universal and Titegroup for suited applications.

IT depends on the load leve. Universal at low pressures wont burn cleanly. TG & BE can both scorch the outside of the cases & leave a lot od crud in the gun as well.

Of those two, Universal Clays (I suspect you meant Universal Clays and not Universal) is cleaner but not with low pressure loads.

Haven't used Bullseye.

That said, I use Titegroup for general practice loads. W231 is grungy, but I find it so darn useful.

9mm and 45 ACP.
