I tried one rabbit shooting once ( we have a lot of rabbits here, a lot). The box mag sucked. Big time. You could not shoot one, load one, and keep the gun topped up. If you have a lot of targets, its not ideal.
Currently...Sako TRG 22, Model 29 .44 Magnum, Beretta M9 9mm, Beretta Neos, Colt AR 15 x 2, VQ 17 M2, Anchutze .22 hornet, the ultimate 10/22, LOTS of M1 Carbines.
