Hi all. I am looking for some info. I hope someone can help. I have a winchester model 70 supershadow. I know it has a 1:10 twist rate. It sports a 22 inch barrel the thing is I have been looking for some load data that some may have that works for them. I am using a load that I think is the best so far but I think I can get better . I also would like to load with more powder in the case. You know I am only getting about 2/3 full with the load I currently have. It is a 55gr sierra blitzking on 35.5 gr H4895 w/ winchester wlrm primer. I cant seem to get bettter than 1 1/2 at 100 yds with anything else so far . Any Ideas?
