Re: wildcat bullets

Berger bullets lists the BC of their VLD's. I have found that simular weight Wildcats must have nearly identicle BC's. So I've used that to get me in the ball park. Then of course chrono testing and range time will give you the true effective BC.

They don't make a 175 7mm But i would imagine that it's BC might be in the .680 or so

Re: wildcat bullets

Sierra 175 gr MK have a BC of about 0.60. This would be a good place to start from on a trajectory calculation and then as was suggested make your own corrections as always.

Re: wildcat bullets

I would say start with at least a BC of 0.650 and figure it up from there. The 169.5 gr ULD RBBT in 270 cal has a BC(derived from bullet drop testing out to 1000 yards) of 0.740.

It would not suprise me to see the same BC with the 175 gr ULD RBBT in 7mm or at least very similiar. Remember this is derived from bullet drop tests out to 1K, not from velocity comparision over long range so those ready to pound on the keyboards, go get some coffee and relax [img]/ubbthreads/images/graemlins/grin.gif[/img]!!

Any of the BCs offered will get you close at moderate ranges, then its time for you to do some work and figure the exact number for your unique situation.

Good Shooting!!
