Range results
I posted these results on another board, but there may be some interest here with regards to the performance of MN's with and without the bayonet so heres what I found this weekend:
Bought two packs of ammo... corrosive Hungarian heavy ball, and a pack of Brown bear 7.65x54r...
Fired the Brown bear first... and after a couple clicks to adjust for this ammo, I had a nice shot placement just below the bull with shots within an inch and a half of each other(17 holes), and just below the bull. Once this pattern was established, I attached the bayonet, and carefully squeeze off the remaining 3 shots. The first one was about 6 inches above the bull and 6 inches to the right. Second shot pretty much the same place. Just to make sure zero hadn't shifted, I dropped the elevation knob down 4 clicks and sure enough the last shot was below the previous 2 and still to the right of the bull. I was pretty much convinced that the bayonet does indeed influence the harmonics of the barrel.
I then wanted to know if the pattern would be tighter, but only had the Hungarian ball ammo left, so it's not a fair completely fair comparison.
Different ammo not to mention the barrel now being at least warmed up, and the crud from the previous shots. Still with the 20 remaining shots, I zero's in with the bayonet attached, and after the 4th shot was tearing the center out of the target. If I concentrate and don't jerk the trigger, my 91/30 delivers slightly over 1 MOA at least with Hungarian corrosive heavy ball. Bottom line is that the bayonet definitely impacts the resonance and POI.
All shots taken at Clark Bro.s Warrenton temp about 50 and no wind to report.
