While real accurate with the ammo it liked this 77/22 All-Weather boatpaddle would not hold zero session to session.
Other accurate .22 Mags...
Marlin 57M...would put as many shots as you wanted to shoot into a 3/8" group at 50 yards with most any of the 40 grain rounds...if you switched to the 30-33s it would run 2"...
Savage 24 DL...same...loved 40s but groups opened up with the light weight Magnums.
TC Contender...shot this group the other day...40 grain Winchester HPs...at 50 yards.
Had a 16.5" Carbine barrel for it that would run 1/2"....
