STRIKER is a repeater.
scope mounts to the receiver, not each barrel.
takes a little longer to change a barrel.
barrels can be had cheaper by shortening rifle barrels.

I can shoot about as good with either one.

contender has more grip options. Pachmyer is great on them.
You have to go to the encore to get a .22-250 or .243
45-70, or .30-30, 7x30 Waters, 44 mag would be the big generic chamberings for a contender or G2
you have to brake it open to reset the trigger if you do not fire it, or go the the newer G2 or encore with a lesser quality trigger.
you have to use easy to R&R rings if you have multiple barrels, or buy more scopes.
