About Raven Eye Custom Rimfire Rim Thickness Gauge For 22LR

RAVEN EYE CUSTOM RIM THICKNESS MEASURING TOOL A must have for any owner of a rimfire rifle that wants to reduce group sizes by increasing accuracy! This gauge has been designed to measure the rim on 22LR and 17 Mach 2 ammunition, and will not work with 22 Mag (22WMR) or 17HMR. Manufactured from aircraft quality aluminum (Al 7075) and anodized for durability. "GROUP THERAPY" Have you ever had a flyer? It would have been an amazing group except for that one shot. The first shots made a single ragged hole. But THAT shot was off just enough to ruin the group. Did you flinch, jerk the trigger, or time your breathing wrong? Who knows, but in the end you just missed making that perfectly tiny group. Was it your fault, or was there something else that was a factor? Could it have been the ammunition? YES! But, on that group, you'll never know. Hopefully this didn't occur during the final round of a benchrest competition, or when you're at the range bragging to your friends about how accurate your new rifle is! With all the money that is spent making our rifles more accurate, it makes sense to examine the ammunition we use as well. From now on, make sure you own the tool that will help reduce the likelihood of having an ammo related "flyer". NOTE: In order to measure the rim thickness, you need the rim thickness measuring gauge AND a dial indicator OR a set of dial calipers. These can be purchased here on Amazon for as little as $10 for one with 1/1,000" (0.001") precision, or for around $40 for one with a 1/10,000" (0.0001") precision. I recommend one with a precision of 1/2,000" (0.0005"), which cost around $30. Directions for use can be found on the manufacturer's website, Raven Eye Custom . com
