i luckd out the other day an pickd up a iver & jhonson cycle works later model .....not black powder, for $100 ! got a box of magtech 85gr 680fps to try an she shoots great. got a lee die set new for $40 at natches shooting online as well as a box of 71gr coper coated rn ( berrys 250 pcs) for less than $20......loading them with hp38 at the 1.4gr from the chart for 85gr to start......then work my way up. cant find load for the 71gr, found on a post for 77gr of 1.5gr bullseye,so i think the load for the heaver bulet would be a good start point for the 71gr jacked. gonna crono it an see,just looking for around the 600fps or so......not the max 800fps it says you can load.
