[QUOTE="Darrell Holland, post: 257960, member: 7708"] Dear Pat. Greetings, if you are shooting a handloaded 168 SMK at 2700 fps. you are still traveling 1206 fps at 1000 yds. the speed of sound is roughly 1120 fps at 3M elevation at 59 ° with 50% humidity. In other words you are on the edge given those parameters. If you shoot a 175 SMK which has a higher BC you will be traveling 1312 fps under the same environmental conditions. This gives you a better cushion of down range performance and keeping the bullet from going sub-sonic. Given the opportunity, always shoot the bullet with the highest BC for your intended application. With the above data you will require approx. 34.5 MOA with a 200 yd, zero for the 168 and 33 MOA for the 175 SMK. Your Leupold Mk 4 should have sufficient elevation to accomplish this. Best of luck to you... Sincerely, Darrell Holland [/QUOTE]
