3" groups with a rifle like that is for damn sure nothing to write home about. Most of us here know the m193 ammo is garbage. Or for better use of terms, "fu cking chidt"... If you are going to continue to use it and shoot your 6" groups, you'll likely not get any useful help from anyone here.
How many of us have to tell you this before you start believing us?
Actually a 3" group with that ammo should probably be considered excellent. It's design spec calls for all impacts to be within a 2" radius of POA.
And I'm quite happy with the performance from it that I'm getting. Several responded with quite apt and helpful advice to my request for group diagnosis. My technique has improved accordingly. And my groups have, and continue to improve.
Am I gonna shoot MOA or even sub 2" with it? If I do, I'll crow a little, but neither MOA or accuracy bragging rights are my goal.
Like I said, Several have responded with helpful advice. Even some of your advice has been very helpful.
My thanks to all.
Am I ever gonna shoot like I did when I was 23?
Reason says not. And the details of that are boring, but now that I've got this carbine, I'm enjoying using it
