i have a early 2000's Ruger 10/22 , it cycles great with CCI stinger but not well with bulk as a result of that and time it only has maybe a brick thru it.
so for many years i just used cci stingers , it was primarily my squirrel and vermin gun and this was fine i really didn't shoot that many of them
i tried some bulk when the kids got old enough to shoot it, and it still didn't cycle well I cleaned it completely and tested it with a mag of bulk and 10 for 10 it cycled and fired so i take it to the range and 50 rounds in the problems start again.
take it home clean it again and go back 50 rounds or so and the problem starts again
i have some federal value pack and some Remington copper plated the rem is what i was using mainly to use it up as it's accuracy is so so even from my other 22 target rifle it seems to be very dirty i am not sure of the age of it but it will be gone soon
I plan to buy cci bulk next and try it, it works well for accuracy in our club rifles for our juniors program and the club prefers only non plated rounds for the 22 silhouette range
but what works to smooth out a 10/22 cycling so that it cycles bulk 22 ammo better.
the older 10/22 doesn't have the issue
