I'm goin to try them on a Sitka Blacktail Aug. 1st on Kodiak, then a sheep a couple weeks later.
What does AB have for a BC?
0.308 g7. They have pointed dtacs listed as 0.302, nose ring would reduce that a little.
From a 20” 1:7 twist, they confirm out at .286 G7
The Custom gives no BC (well everything is a 1.000). It is what AB measured and I trust it more than the manufacturer. So I was plugging in the same MV and seeing drop and drift at 1000 yards in standard atmospheric conditions and 10 mph wind to get an idea of how they compare.
Here are the comparisons. All were using an MV of 2800. You will have to decipher. Drop and drift are in mils. Based on drop and drift, ABs custom is closer to the 0.308 than it is to 0.286.
Copy. Mine is a sample of one, using a Revic BR4. It’s spot on out to 1,000 or so, though past that, it seems the B.C. Is a bit higher. Their starting velocity could be higher with a longer barrel as well. I’m at 2940 fps.
I bet, at least in your rifle, yours is correct and AB is wrong. I'm not smart enough to know how a gun might influence the BC.
I’m no expert either, but what I understand is that twist rate and velocity influence the B.C., as well as the B.C. changing at different velocity spreads. Hornady will list 3 different B.C.’s for the same projectile at different speeds.
