Well finally a full tune and its all back together with new maccari e3650 spring, a telsa seal and a GRT 111 trigger... thanks to support and good help from gta friends, no parts left over lol:) It looks good so far and thought I would share first results .. its late so only fired about 35 shots 15 to sight in and 20 on target to compare with target shot before starting my tune up. Both targets where shot identically (5 shots at 5 targets) using arm on a rest and holding the front of stock no back rest. I will try further pellet tests and a chrony check on the weekend.
