Anyone have a Hammerli 850 Airmagnum that was "tuned" such as the service through the "850 store" but still retained the CO2 powerplant and not converted to compressed air?
I'm pretty happy with it as is for its combination of low cost, quiet report, power and convenience of CO2 vs requiring PCP/compressed air but I'd like a slightly flatter trajectory with slightly heavier pellets. Specifically it seems to like pellets in the 14ish grain range, any more than that makes for rainbow ballistics and the groups open up. Strictly speaking I would probably not want to ship it off but I am curious about this potential mod because it doesn't seem that expensive but I can't find any info on people who did it.
Was it worth the 120 dollars and shipping? Did it improve accuracy or range or power in a way that improved your ownership experience or not, and if so, how did the "tune" affect the gun?
