BC question

[dragman]

Got some 285 eld-match when they first came out. BC - .789
The new listing for them on the web sight is - .829
I just ordered another 15 boxes and haven't got them yet but a change that big is really strange IMHO.
Anyone have any insight on why it changed or if there was a statement from hornaday that I just didn't see.

I know they're doing a lot of doppler testing of their BC's and most people report that the numbers are pretty accurate. They may be refining their numbers as they get more testing data. Also, I noticed that they are using one number for "comparison" purposes to match up to other manufacturers' published data, and another number that they recommend to use when shooting beyond 600 yards. (Mach 2.25 vs Mach 1.75 BC's). A bit more info in this article...

I always wonder about the science vs marketing input to determining advertised BC's. I see they claim a 0.417 G7 BC which is the more applicable number. Berger claims 0.421 with their slightly heavier 300 grain. So they are in the same ballpark. I guess only actual testing will tell whether or not those numbers are realistic.

It's only a 5% increase. Until tests show otherwise, I would just assume they have better numbers now.

But 5% at that high already is really a lot. the higher the number the more diminishing returns so ever single % is a big deal at that point. especially since in a 285 it's over the published BC for the Berger 300 grain. Either way I am hoping to get them shooting soon so I can see what they actually do at long range. That should be the tell all.

I figured on some movement in the refinement process this was just way more than I figured.
