If you really want your groups to shrink.You have to tune her. New seals, a bushing kit for the breach and for the nitro piston. Available from gene sc in the airgun mall.Use the proper lubes and you will see results.With better equipment, comes better results, and a better experience.Although not the same gun, my stoeger can do impressive groups at 24 yards, smaller than a dime. Best was .464 oto and .262 ctc at 24 yards.That didn't happen after 500 shots, that happened after going crazy on tuning her, and having her professionally crowned and the GRT111 trigger and trigger tune.Keep at her, eventually the tuning bug will bite you.
