Hi, I just got a 1917 Eddystone that had been 'Sporterized'. Luckily it was just the stock. I did some dealing with flydoc on a full length stock(no handguards).
I loaded some Lee 150gr RF boolits (153.5-154.5 naked) Shoed them with hornady cks and lubed w/ speed green, all loads were with alliant 2400, loaded 2.960 C.O.A.L Fed LRP no filler
This is first target at 50 yrds with iron sights POA was base of big diamond
Load 16.5 hit 1" low and 3" left 1535 fps avg
after sight adjustment
Same POA 18.5 gr hit 1" rt 4" high 1730 fps
upper left diamond shows 19.0 gr 1" rt 3" high 1790 fps
lower rt diamond is 20.5 gr 2" left 2" high 1850 fps
Nothing to get excited about
