Maintenance isn’t just about cleaning your rifle after hitting the range. There should be a repeatable process you have when it comes to the upkeep of your firearm. Here is what I do, and this works for me pretty well… I recommend a deep cleaning and proper maintenance (check torque on all screws) every 100-200 rounds. If you’re shooting a lot at the range, check torque specs on action screws and scope rings before every range session.
On your hunting rifle that only gets a preseason sight in and a few rounds during season, clean, check torque and zero before and after every season. Failure to clean your barrel after use can result in inconsistencies with your (internal ballistics). Carbon build up can turn your sub-MOA rifle to a 2+ MOA rifle and it is a difficult and long process to get rid of it. Be sure you stay on top of your cleaning!
Keeping a toolkit in your range bag is key to being able to fix things on the fly. A set of “fix-it-sticks” is highly recommended for anyone serious about shooting. Knowing is part of the reliability of your rifle, “know before you go”. Be confident in your gear before you take it out, confidence in your gear leads to confidence in your shot. Do not sell yourself short by being unsure of your gear due to lack of maintenance.
