[QUOTE="Darryl Cassel, post: 5759, member: 34"] Big Sky I do think S1 is the one on the wackey weed "if" my BC is correct from Sierra. The 120 Gr 257 HPBT from Sierra has a listed BC of only .370. At 5000 feet elevation and with a speed of 3400 FPS it has a remaining energy at 1000 yards of only 597 FP and a remaining speed of 1515 FPS.

Even the Oehler program shows the Sierra 120 gr at the low BC. Later DC [img]images/icons/wink.gif[/img] [/QUOTE]
