If I had to make a guess, I would guess that the lift effect would be less for a longer heavier bullet if you shoot it from the same twist barrel. Reason being because a longer heavier bullet will have a lower stability factor than the shorter lighter bullet (from the same twist barrel), and I suspect the rigid axis/lift effect will be related to the bullet stability.
In other words, I would expect the longer heavier bullets to have drop that's more in alignment with a normal BC.
But that's just a guess (shrug).
Remember, we know that they will not follow the normal G1 BC profile. Using the G1 profile for these is just for comparison purposes and for the shooters to have a general idea of what to expect.... Again, we know they do not follow G1 profiles (normal bullets).
Using the Don Miller Java-based program you sent me last year, here are the following SG values:
265 grain 1.765" @ 3245------> 1.67
280 grain 1.845" @ 3150------> 1.54
300 grain 1.935" @ 3000------> 1.41
In reality, the Generation I bullets were a few thousanths longer than the associated Gen II offerings.
like I said before, they followed the G1 profile with great predictability.
Do you actually think the .004 increase in SG in the current Gen II 265s is causing a possible nose up when the Gen Is being .004 lower were spot on with the G1 profiles?
