Can You Shoot MOA All Day Long? Yes, I can!
TFB’s Pete asked before if we can shoot MOA all day long?
That’s over a year ago and I’m sorry I haven’t replied earlier but “I was busy“.
However that doesn’t mean I can’t, and this time I brought back some proof to share.
Typically I shoot 5 shots to get a grouping, or an indication where my hits are. Low, high, left or right?
This time I was testing a new ammunition for a Ruger Precision Rifle Gen 2, Norma 6,5 Creedmoor 130 gr. I shot one group which was OK, just to confirm that the sight was adjusted and zeroed. Then I shot the one pictured with some more focus, and I have no doubts it’s repeatable. It feels like a laser.
As Pete asked, here’s a reply in the format you wished for. Sorry I pushed it a lot further than the 100 yards:
Results:
Eric B., Ruger Precision Rifle Gen 2 (not mine), stock apart from no muzzle brake. Caliber 6,5 Creedmoor. Kahles 624i in a Spuhr mount. Norma 6,5 Creedmoor 130 gr.
The Ruger had an Atlas bipod and a support bag at the back.
Grouping: 5 shots within 7 centimeters (2.76 inches) at 300 meters.
To the best of my limited knowledge about mathematics that should be 0.8021 MOA.
Actually I got a little help from this online calculator.
The target was at 300 meters (328 yards) and a 10-ringed ISSF approved paper, wired to an electronic target system. Perfect for instant feedback.
The ring 10 is 10 centimeters in diameter. The width of each ring is 5 centimeters, as marked in the picture above. This means there are 5 “ten-tens” or “inner tens” in the group, a clear 50/50 in score.
In fact, the three first shots were approximately 3 centimeters apart, which is insane at 300 meters and around 0.35 MOA.
Below: The ammunition. I approve. Pretty good for a factory load.
And I have more material to do part 2, 3 and so on of this, with other rifles. I have also tried a few other rifles, that I think are unable to make sub-MOA groupings.
Next up is 5 shots through a 20″ barreled AR15 shooting 300 meters with 52 grains Hornady Match BTHP, how do you think that went? Using a Zeiss 1.1-8x Scope, with what seemed like a “huge” reticle.
So get your rifles and cameras out and start shooting and documenting those sub-MOA groupings, that includes the TFB staff too!

Did you have a stroke? How is a five round group "shooting MOA ALL DAY"?

Here ya go! Two 10 shot groups! Now, follow me on this.
2 x 10 = 20 but 5 x 5 is 25! So I'm missing a group, but WAIT! If you multiply 2 x 5 what do you get? 10, but 10 minus the original 2 is 8 plus it's TWO targets which equals 10 but you must divide by 2 which gives you the 5 you are looking for! So with the original 20 plus the 5, you now have 5 groups! TADA!
...and in case anyone cares.....100 yrds. with a .308 RPR 20" bbl., el cheapo 24x scope, 168gr PMC Match ammo from a bipod and sandbag with negligible wind and blistering sun.
