[QUOTE="MontanaRifleman, post: 828273, member: 11717"] That is a sweet looking rifle. You can easily determine the effective range of the bullet you use by using a ballistic calculator. A .5ish BC will be borderline to 1000 yds at PA elevations, using 1800 fps as a minimum opening velocity. For 180 gr bullets you can expect velocities in the range of 3300-3400 fps. In order to get the most out of the RUM, use heavier bullets. I plan to use the 230 Berger Hybrids in mine with RL33 as first choice of powder. I'll also be trying 200 gr Cutting Edge Bullets with Retumbo. There are several advantages of going with heavier bullets. Most being in external ballistics of greater BC for greater range and less wind drift. Also more mass and destruction delivered down range as well as slower short range velocities for more controlled expansion and less damage. Also slower burning powders with lower velocities will increase your barrel life. Everything about the bigger bullets is good. If you want to shoot to 1K, you will probably want to get another scope that you can reliably dial your corrections. I highly recommend the 5.5-22 Nightforce. Welcome to LRH [/QUOTE]
