I've done a bit more work with the old 140. I took the 130 pivot block off, and put on a modified 13-89 block, to give the bbl a bit of tightness. I also cleaned up the transfer port opening on the bottom of the bbl.
5 of the JSB Exact Heavy at 12 Meters. It looks like I'm getting the vertical stringing a bit more under control. That's 5 pumps for each shot.
Here's where the old school comes into play:
That's an early 60's Weaver B-4 4X scope. It groups well at 12 Meters, despite it's uncoated lenses and 50 yd parallax setting. That old Weaver has taken a boat load of grouse and rabbits for me. It sat for years atop my 52 repro....
Burris tip-off rim-fire rings. Hard to come by these days. I stumbled across these at a small rural gunshow years ago, and jumped at them.
I think in order to fully test this 140 bbl, I'll have to get it into a sbk steel breech.
I'm kinda torn about how to accomplish that. I do have a phase 2 13-22 that the bbl will direct fit into the modified SBK breech. The difficulty comes in deciding whether to further modify that breech to line up with the breech screw hole on the 140. That of course opens up a whole 'nother can of worms for me- to inlet the stock for a breech band for the SBK breech or not??? I really do it to myself at times
