The above image displays the result of my experimenting with Lyman's not-so-loved 311414 @ 153gr., Privi brass,16 gr. A2400 ignited by WLR primers. A soft lead sinker shoved down the K-31's throat indicated a .299 bore\.307 groove depth. After sizing a test boolit to .308 dia. in Lathesmith's H&I with the perfesser's G, the Boolit was then seated to where the case mouth barely touched the rearward portion of the leading drive band. Just a hint of rifling on the ogive after extracting the test round.
Nine rnds. were fired at a 100yd. steel plate to get my groove on with trigger pull and open sights. It was love at first bang\clang. Remaing eleven rounds at 50 yds. are responsible for the holes in pictured SR1. First two shots @ 2:00 in nine ring.

Without Lyman's Hawkeye diopter all this would have been, mostly, an exercise in futility. These devices can add years of shooting enjoyment to old eyes. Certainly brings the rear sight notch into focus.
Be of good cheer,
Harold
PS: didn't notice the poor image quality till I loaded it. Looked good in the Nikon view finder...
