I notice a lot of guys using 22lr for a substitute trainer obviously for the cost reduction and absolute thrill I'm sure. But I have a 22 mag sitting around here and was wondering if anyone on here uses a 22 mag for a sub and what type of results guys are having? Also, would love to see some pics of those precision 22mag!! I have a marlin model 25MNSS and have been thinking about making some tacticool mods. I want to push the limits of this caliber and was just looking for some advise and insite before I get started so I can avoid (if at all possible) buying and rebuying due to lack of knowledge of whats out there and available with this project in mind. wanting basically to shoot as far as possible accurately with this rifle. Target shooting, Varmint, and what ever else. Would people, with experience, consider sticking with the micro-grooved barrel or swapping the barrel for something else? any advise or input would be greatly appreciated. Thanks in advance guys.
