Well, went to the range this morning and blasted off the last of the lead rounds I'd loaded, 6" group as expected (range is 20 or 25m not sure which!).
Then tried the 10 I'd loaded with reduced crimp and another 10 with reduces crimp and original slightly shorter length, first couple were 2" apart and I was almost happy until the next 8 went all over the place as usual
So, back to the Berrys copper plated and doing my best not to screw up I got 15rnds in a 1" group, did this 4 times in a row so I will def have to stock up on coppper plated, I know Lean at Bold Action have Frontier 115gr listed at €71 x 1000 so not much more than the Berrys I got in the US.
