I use biggameinfo.com

Semisane

In the Black Powder Reference Forum.

I have use all the ones mentioned by the guys here, and they all do the job but here is the one I like best.

I really like the ballistics program from the hand loads site since it can figure up your approximate BC for unknown projectiles. Thanks for posting that!

i feel like the bc on the handlload one isnt to accurate because i heard that the barnes expanders bc was .204 and when i plugged the numbers into the handload one it came out as .168 or something close to that

But other than that i like the handload one alot easy too use...Thanks every one

BCs are a floating number anyway, dependent upon velocity and the whim of the gods. You can pretty much expect the BCs published by bullet makers are either optimum or optimistic.

The numbers may be off, but it can give an idea of what it does down range. I cannot find BC's for most cast conicals/bullets so it gives me a rough number to use. It can't possibly know the exact number as there is such a broad spectrum of "SWC" type designs. And a RN could be perfectly round or oblong. For me it's better than guessing...

Perhaps. For the most part i have found most all bullets fly as well or better than ballistic program calculation say they will. This very well may be because most all of my shooting has been at over 3000', and lately most of my shooting has been over 4000'.

Yesterday from actual clocked velocity, this here ballistic program calculation the BC of the 270g Deep Curl to be 0.213. This is significantly higher than Speer published BC for this bullet of 0.193.

Please don't construe what i wrote as disagreeing with you, i wish not to suffer your wrath.
