I have a Franklin Arsenal pair that I use to check the OAL of my rounds when I reload . They work fine . I also have a pair of Midway non digital calipers .
I have been taking Gabapentin for several years . I have been taking it for Restless Leg Syndrome and a muscle relaxer . It hasn't done anything for leg pain .
p.s . --- I am finally getting the torn meniscus in my right knee repaired tomorrow .
On my last deer , I tracked it into a Soy Bean field . I ended up tearing up a handkerchief and marking the field . That marking kit looks like a gimmick but I sure bet it would work and be very helpful .
