Hi guys, went for a shoot at the range with handloads some promise with 90gr and 91gr AR2225 two touching one left of POI with both loads the 90gr load the third shot is about inch left and down the 91gr load is about 1cm left and down. SO im thinking some tweaking is in order so back home thought I would check measurements to the rifling now past measurments came up 2.945 with comparator. Last time I measured I used hornady OAL gauge with dummy case with slight pressure on gauge to get past measurement but this time I applied a bit heavier pressure and the proji went in to 3.133thou on the orgive that 88thou longer than previous measurement. So next I sooted up a proji and began seatting it in a fire formed case and got no rifling marks until 3.110 at the orgive so Im assuming the 3.133 measurement is jammed so Im asking what the heck was I getting my very first measurement of 2.945 from this rifle has approx 40 rounds down the tube so cant see it been throat wear. Im no longtime guru handloader so your thoughts would be helpful have I missed somthing or have I had a DOH! moment. Cheers Rumball.
