That's some very excellent strings.Your strings from your .22 M-Rod is better than my .22 BSA Scorpion T-10 using the same pellets you used....I never played around with any of it's settings.You've got 35 shots in the 900's vs 21 from my T-10.Then you've got 14 in the 800's vs 23 from my T-10.I continued shooting till I got to shot 70:From shot 45 to 64 I was in the 700's = 20 shots.Great looking Marauder you've got there.
