For FMJ/plated, my favorite is VV N340! Titegroup works well, W231/HP38, WST for lead, of course Bullseye.
There are SO many options! Many of the shotgun powders work wonders: Clays (most of the family), Red Dot, American Select...
If I could only have 1? VV N340 would be it (provided I could actually find some and afford it!).
