Zukiphile... my 10/22 pictured is considerably heavier than a Wiland with carbon fiber stock and barrel, but still swings well with a steel barrel...and I like it as it uses familiar AR butt stock and grip... the problem I encountered with the 10/22 was the reliability of the highly regarded 10 round rotary magazines... I purchased 6 new mags with red rotors and could not get the reliability out of them, but never really spent time working on the solution... I did measure them, and there was a .015" difference in front to rear between them and which when shimmed tight into he mag well helped with reliability
my current Steel Challenge long gun is a registered Short Barrel Rifle with approx 10 1/2" CMMG 22 barrel with a CMMG B collar conversion unit...with good ammo, it has been very reliable.... I like the ease of cleaning of the bolt face and feed ramp and access to chamber and barrel by simply pulling the unit out of the receiver of the AR.. the 10/22 required removal from the stock and trigger group to remove the bolt (even if you have a hole drilled in the rear of the receiver).... I use Black Dog mags with stainless feed lips...and the feed ramp on the collar I perceive to be a better solution than having the feed ramp and ejector on the feed lips of the magazine as does the 10/22....it swings very fast, and although it is heavier, the weight is in the rear and gives stability... I like that the high capacity magazine will give me 3 strings of fire before I have to interrupt to change magazine
a friend with a M card has a CMMG chamber insert in a 16" 5.56 barrel and he gets very good results... a couple of friends use the plastic SW 15-22 and if you watch for feed lip wear gives them pretty reliable results
if I had not had access to the SBR and short barrel prior to starting Steel Challenge competition about 2 years ago, I would have taken more time to work out the reliability issue with the 10/22.... the 10/22 has tremendous after market support in the Steel Challenge arena ....a Chevy Truck STC 10/22 I built in the mid 90's was capable of 1" at 100yd with a barrel tuner.....I don't need a lot of accuracy to shoot a 10" plate at 15m..... I never really shot the AR with 16" barrel in the speed events of Steel Challenge, to give it a true evaluation...
I originally got the CMMG chamber insert and later collar units as a rimfire trainer for 3 gun.... I can't run any longer so Steel Challenge is a refuge for old farts that still like to play... regards Les L747
