I don't know for sure if it was the new barrel I picked up yesterday or the new way of loading my RB I tried last night but it's finally come together.
The load is a .690 Lee RB, water quenched loaded on top of a believe it or not 19mm stick on felt furniture leg protector in a Winchester AS 1 1/8th oz shot cup pushed by 25.5gn of ADI AP70N (Hodgdon Universal) in a Champion high brass blue hull.
I picked up a 20" smooth bore barrel with fixed rifle sights for my Adler A110 lever action and wanted to test it out.
The 1st shot at 50 yards hit the bull followed by two touching an inch lower, I decided to try 2 more with the 4th shot a bit low and 5th touching the other two touching shots.
I patched out and decided to try another 5 shots and ended up with a 10 round group at 50 yards about 3.5"-4" I will it measure later.
I'm very happy with it and I've definitly got my 50-60 yard pig and deer load all sorted and I'm will to push it to 75 yards without flinching.
I'm going to to hunt with this gun now until I've got a deer on the deck, the pup needs the experience anyway.
But I've definitly got confidence in this load now.
It's been a long road but it's all worth it in the end.
