My best ten-shot group at 100 yards with .22LR

[grauhanen]

I've shot 100 yard ten-shot groups in the .5's this season, even a few in the .4's. This morning I shot ten groups including the best one I've seen. It measure 0.583" outside-to-outside, making it under .400".






The lot of Midas I used was otherwise unremarkable. The box from which the rounds that produced this group had an ES of 33.4 fps and an SD of 7.1. The other box had an ES of 46.8, an SD of 8.5. Temps were just above freezing.

Of the ten ten-shot groups I shot, one other was small, in the .5's. The ten groups averaged near .900" with a couple groups over 1".

The rifle was a new Anschutz 54.30, which I've had for three weeks. It is shown below.

.359” if I mathed right.


Thats fantastic shooting.

The internet is full of half inch/hundred yards groups, it's just that, although almost everybody now carries a camera in their pocket, they somehow forget to take a snap of these remarkable groups.
Good shooting indeed.
What annoys me is the inconsistency, of even top quality .22lr ammunition. I've little doubt you shot just as well for the 1"+ groups, just the ammo let you down. A 3-4% variation in velocity is not good. If you were shooting precision centrefire I don't think you would find a variation of 100fps acceptable.

Thanks for the kind words.

That's a good observation.

Ammo that gives consistent results at 50 usually doesn't at 100. It's not difficult to shoot ten-shot groups at 100 that are under one inch. But it's far more challenging to produce ten consecutive ten-shot groups under an inch at 100. Too often the ammo isn't up to it.

I’d be really excited. Fantastic stuff.

(Of course I myself have learned to regulate my excitement, as precision is a fleeting mistress)

A phrase from way back regarding accuracy:

'What's it 'ag' ?

You, that rifle and ammo would do very well with this target:


I’ve shot that target with my 40X several times, seems that target doesn’t like me….
