I will probably Not use Nitro 100 with Heavy boolits.. other better choices... but, with lighter Boolits... it works better for me than Red Dot... which shines with Typical for Caliber Projectiles!! Too Bad it is Unobtainium these days in these parts.
Currently experimenting with the Lee 200gr RF for my 44's. So far, not quite as successful as the 125's in the 38SPL..
Maybe I will seek out a 180 or so for the 44..
