just got my contender carbine barrel in .17m2.
put a simmons pro airgun scope 6-18 on it.
wow! is this thing accurate! i cleaned the barrel with sweets every ten rounds up to 100. it grouped all over the place for the first 20 shots or so then settled into about 3/8inch with a flyer now and then.
then i switched from hornady to cci and the flyers went away!
i was shooting golfballs at 50yards. and bowling pins at 125. from a rest, it was boring after a while.
i got this barrel for squirrel hunting. i generally use a .22 carbine barrel for my contender, and try to head shoot only! this new cartrige will extend my range a little, as it shoots very flat.
