I had a 17 HMR barrel on the the gun and it was recalled by Remington so I had them put a 22 Mag barrel on the gun for free. First shots today with 40 gr PMC HP 2" at 100 yds and Winchester 40 gr HP went into an 1" or so at 100 yds. Only glitch was the mags. I had to squirt them with CLP to get them to feed properly. Once they were slicked up they worked perfectly for a 100 rounds. All in all , I'm happy with the conversion even if it was free.
