i am about to start shooting 500-1500 yrds. I am using a remington xcr in an acis stock. I have put a swarovski 5.5x25x52 on top of it. I am looking for any information that would help....... Load work ups that have worked at these distances (i know each gun is diffent just using as a guidelines) bullets that are being used..... best ballistic chart....... How do I offset if my scope only has 48 inch elevation......... what else do I need to know. I have been shooting for along time,,,,,, just never over 500 yrds
