Im after the BC for the stack of factory bullets I have for my 243
its the 80gr winchester soft point one, use to be white box now its changed its box but the bullets seem the same
dose any one know where there is a record of the BC of these bullets? I have a chrony ready to put them over
cheers
Is this your projectile? : http://www.winchester.com/Products/r...ges/X2431.aspx
BC looks to be 0.255 (G1)
I think thats the one, its hard to say with the fancy new packet, man .255 is very average
Ill run the numbers with that and check to see if it fits
cheers for the help
Sounds about right to me, 80gr in .243 is pretty short. plus the winchester soft points are fairly basic cup'n'core style bullets.
Might be on JBM
Nope, JBM only has 55, 95 and 100 gr options for Winchester
That's what you get for using JBMQuote:

The Winchester packets I have now have 308 , 270 have Muzzle velocity, Trajectory (+ -) & Energy table on back of packet 100m -500m
They could of put BC on there too you'd think .
Checked on the Nikon Spot-On app, the BC is .255
