RPV bullet BC?

[henry1]

Hello everybody, I was just trying to get some data together on my 220 swift and looked up my last load for it. It was with a 60 gr red prairie varmint bullet. after searching the internet for a bit i was unable to come up with an answer and figured i would ask!

Also during my internet search i found that someone had bought the molds for starke's different bullets. Any one try the new manufactured ones? curious about them.
Thanks in advance friends.
Henry.

to find your BC just sight your gun in at say 100 or 200 yards yards, then shoot at 300-400-500 ect or as far as you can and you can and measure the drop and back calculate the BC, its probly around .3 G1 BC

While your doing the long range shooting, keep the drop figures and don't worry about the BC.

The drop figures are what you have. using the BC and a computer program won't be any closer.
