 Sanner’s Lake IR5050-style Rimfire Bench Rest Match Report
1 July 2018
Weather: Hot and humid!

Given the hot and humid weather it wasn’t surprising that the turnout was light for the July IR5050-style match at Sanner’s Lake, but the two competitors who made it out to the range had the place to themselves while they challenged each other for benchrest supremacy.  Both competitors were shooting newly-built/newly-acquired rifles and spent the match experimenting with ammo selection which is an ideal way to see what really performs under the stress of competition and what doesn’t.  Mark S ran his first string with CCI standard velocity and then switched to Lapua Center-X and finally Eley Tenex and saw his scores increase each time commensurate with the cost of the ammo.  Is winning a match worth the additional expense of high-end ammo?  Of course it is.  David H wasn’t far behind, though, and saw a similar increase in scores with each ammo change as the high individual score bounced back and forth between the competitors.  See all the details in the July Match Report.  The next match is scheduled for 5 August; if you have a rimfire rifle that is (or is supposed to be) “sub-MOA”, this match is the perfect opportunity to put it to the test and see if it truly measures up!
