These groups are out of the park fellas, hats off! I'm a true CZ newbie, got my 452 Trainer out for a second time today, middle of an ice storm but otherwise good conditions.
Once again I failed to bring targets (old age creeping up on me) so I hit the local Walmart which had nothing but big Shoot-N-Sees or target dots.
2 5-shot groups, scattered 5 were SK HVHP, rounds 1-5 from clean, 26-30 lifetime. Group was Aguila SE Sub 40 gr. RN, rounds 36-40, 61-65 lifetime. I kicked myself for not sticking another dot up instead of re-using the sighter.
Stock 452 Trainer with .010" sear shim, 14 in. lbs. torque, stock tangent sights, 25 yds. rested.
Humble as it is:
I know I don't need better for squirrel gittin but man you guys make me wanna practice more!
