I am considering using a replacement for Bullseye powder. I like a fast burn rate like Bullseye because it does not seem to be affected by small variations in neck tension and lower pressure loadings for 38 special. What I would like to improve upon is the hot burn temp and secondarily, a reduction in sootiness. Does such a powder exist or is the hotter burn temp just a characteristic of fast burn rate powder? I’ve tried slower powders like HP38 and Universal, but the “pop” isn’t nearly as consistent as with Bullseye. I thought it could be a powder metering issue, but HP38 meters as well as Bullseye from the loads I’ve tested.
