[QUOTE="tjonh2001, post: 193941, member: 8970"] thats the thing i use leica geovids and a kessel. i have done alot of reading here and other sites. i am wondering if you guys find a chart on you exbal that coinsides with your performance and use that as your performance numbers. velocity 3160 and a bc .648 in the mauals. when i put it in my exbal i have to change the bc to .64 fps to make it match my chart. so now when i am at a different altitude i should use those numbers and i can just change temp and pressure and i should hit my targer. is that what you guys are saying [/QUOTE]
