I decided on a gamo Varmint Hunter for another project. So far I’ve barely done anything to it besides the basics. I tightened the spring guide up, installed my flavor of piston sleeve, polished various internals, and that’s about it besides a good cleaning and proper lube. I’m excited to see if I can get the stock trigger unit in shape, the GRT-III does so well in these, I’ll keep that as a back up option. I’m certainly happy with the spring, and despite having a dinged up piston seal, it’s shooting consistent velocity. Got to say these Hunter series guns respond very well to a little internal care.
I only shot 15 pellets through it to a target. Exactly 20 yards. My first was a 10 shot group with a 3 fliers that opened up an otherwise half inch group. The second was barely under half an inch.
I also fought more with my CFR. It's basically my arch nemesis anymore. Between it and the scope. It was shooting piss poor for a while. I eventually realized with the tools I had available, the only way to seat the pellets consistently (it’s poi is very sensitive to seating depth) is to seat it flush. So once I sat the pellets flush, and once I held the gun tightly with a front end weight bias, I printed a half inch group, learned from that and shot a sub half inch group, also at 20 yards exactly.
