I just acquired a 396 Mountain Lite and with the current ammo situation, I will have to roll my own. I have a supply of Hornady 180 gr XTPs and powers that should be suitable. In the 3" barrel it seems that the faster powders would be best. The powders that I have available in that range are Bullseye, RedDot (Promo), American Select, and Universal. I'm not trying to set speed records, after all this thing is LIGHT, just looking for a load that would be close to a factory 180 gr SD load. Anyone out there have suggestions for such a load?
