FYI and open to any input...
Yesterday, I loaded up some boolits consisting of 23 grains of Triple Seven fffg and the Lee .452-255-RF dropping at 265 grains.
The velocities from my 4 5/8" Uberti were:
855
849
851
863
853
AVE= 854 FPS
Shooting at 15 yards with my wrist just resting on the top of a folding chair (not very stable) I was able to produce this grouping. Point of aim was just at the bottom of the square of duct tape. I think the two loose shoots were clearly my fault and the not the gun's or load's fault.
Any thoughts?
Thanks
P.S.
I plan to shoot this load through all three of my Uberti revolvers on a more stable base to see what kind of grouping I get with them.
