just wondering if anyone has any good suggestions for a 308 win. 500 to 1000 yrd shooting. so far i have got a pretty good one i think with Fed. reused factory brass, 45.5 gr. varget, 168 searra matchking, OVL is 2.820, barrel length 30 in. I tested 7 diff. loads to get this one only changed powder grains. rite now i have a 2 3/4 in. groop at 500 yrds and hit a golf ball 4 out of 4 at 300 yrds. but when i loaded this load in some winchester brass all prept the same, (other than) i noticed the flash hole was not perfictly round, it was lop sided before and after using sinclair uniformer. anyway this same load with winchester brass moved my group for the worse 1 in. so i geuss my question is first does anyone have some good loads that they know. and 2nd is it worth buying some lupua brass for relly good grouping at long range. thanks guys, im sure ill get some good feedback.
