This Marlin was originally a 30-30, rebored to 375 Winchester by JES 2 years ago. This past summer I installed a XS Lever Rail w/Ghost ring sight system and it proved very accurate for me up to 75 yards. Got a Sig-Sauer Romeo5 when DVOR had a good price last month. I really like this 1x20mm compact red dot sight. I took the rifle to the range today, 19 degrees and some wind. I stayed long enough to get this sighted in at 50 yards using the Lee 250 grain boolit powder coated with some Smokes John Deere Green, NOE sizing, pushed by book load IMR4198. Very pleased and looking forward to warmer days and longer range sessions.
