Thread: Sorting 22lr

@zimmer, I am using this Norma Match 22LR Link - but mine comes in a different box.

My testing with 22LR ammunition proved what someone else tried explaining to me when I started testing. My last lot of 22LR accuracy testing involved Lapua Polar Biathlon, Eley Black, SK Rifle Match, Norma Match, and several RWS ammunition types including Target Rifle, Special Match, Rifle Match, and R50. I shot ten shot groups at 50m, 100m and 200m as well as 10 shot strings over the MagnetoSpeed to check velocity consistency.

The Eley Black had the best group at 50m but several of the ammunition types came in with 12mm groups on average. Several groups had occasional fliers as well.

At 100m it was the Norma Match and SK Match that had the best 10 shot groups (about 30mm) by a slight margin over the Eley Black, RWS R50, and Lapua Polar Biathlon. Again there were occasional fliers that I did not exclude from the group.

200m is a serious test for a 22LR and this is where the Norma came through - under trying conditions it produced a 10 shot 2MOA group with 8 shots just over 1MOA. The SK Match, RWS R50, and Lapua Polar Biathlon produced 3MOA groups with most of their shots coming in to a 1.5-2MOA group. The Eley Black did not perform this well at 200m at all.

I have since shot a series of 10 shots groups with the Norma at 200m and it looks like there is on average 1 flier every 10 shots or so - otherwise is was consistently producing a 50mm vertical group at 200m with the fliers up to 100mm high or low.

To be clear I am not the best shooter, have never been a small bore shooter, and all the groups were shot off the bipod and rear bag.

So being happy with the price and the overall accuracy I want to try and eliminate the fliers from the groups. Weight sorting didn't seem to make much difference... so now to try something else.
