I'm new and trying to get some accuracy.
I'm using an AR platform but it is not gas operated -- it is manual as shown below in the picture.

I am trying to shoot economically so I am using light powder charges. I've gone through the .223 type brass using 6.0gr of Unique under the Lyman 225415 with a CCI 450 primer and it did ok at 50 yards. I have not tried dacron in any of my loads. I've done the same with the Bator 2 groove and Bator 3 Groove with about the same accuracy. I use Alox lube and all bullets are sized to .225 and gas checked. I've tried different twist rates from 1:7, 1:12 and 1:14 with, believe it are not, the 1:7 seems to get a little better accuracy. The 1:7 twist barrel is 20" long with chromed bore and chamber. I would really like to get the accuracy down to maybe an inch at 50 yards but the best I've gotten is 1.5" with 2.0" being more the norm. I am using a 3X9 power scope on the rifle -- not the one shown in the picture. I was wondering maybe I should drive the bullets a little faster but I'm new at this and also old and decrepit so I'm limited to going to the range once or twice a month and the 50 yard range is the limit to my walking. Is this the best I can expect or is there something else I can add?
