The weather finally moderated and we got to do some ammo testing. Grandson Lucas shoots on a 4-H rifle team, .22LR, and it is a fine program. Shooting .22LR ammo takes the handloading equation out of the marksmanship program. The best scores come with the best anno, tailored through your rifle and your ability to shoot. Therefore, we test rifle ammunition.
Luke's rifle started life as a Ruger 10/22. It has been heavily modified, with a Boyd stock, a Kidd barrel, and various other parts to increase accuracy and reliability. It's a ice setup and his Dad has become quite the Ruger mechanic
The ammo in today's test was some SK rifle match ammo and some Federal Automatch rifle ammo. I got the Automatch from Wideners. As in all things, the target tells the tale. Weather was moderate at 80F with calm winds. The shooting done from a patio bench at 50 yards. Lucas was wearing eye and ear pro, and all shots were captured on a Lab Radar chronograph.
And there we have it. The SK Rifle Match shot marginally better on a 10-shot string. but the Automatch wasn't no slouch. The Automatch had an Extreme spread of 44 with a Standard Deviation of 15.5. The SK RIfle Match had an Es of 27 with a Sd of 9.4. Both groups hovered around an inch at 50 yards, which will put him inside the 10-ring of the target he uses at competition.
Lucas will have to make up his mind. As for myself, I have some Federal Automatch ammo and I think I'll sight ny rifle in with it at 25 yards in case a varmint needs some persuasion

My club hosts American Rimfire Association (ARA) matches once a month. Those guys are something else. Thousands of dollars spent on rifles, scopes, ammo, bench rests,etc. They are always on the hunt for the perfect combination of all of the above. Their targets are so small I can't even see them without a spotting scope.
