I use nothing but the T\C Pa. Conical....OR the Buffalo Ballette in my 50 caliber. Why?
#1--No patch is required
#2--More weight than a PRB....If it were me...I'd rather get hit by a guy on a ten-speed bike going 40-MPH than a Mack Truck going 10-MPH. Mass and weight outdo speed and lightness any day of the week.
#3--For hunting the Conical (not a Maxi-Ball) is easy and fast to reload.
#4--Maxi-balls are to costly. Conicals are cheap.
