Of course, you're putting a lot of faith in assuming that the published G1 BC for that bullet is correct, and since Speer offers no info as to how BC was determined, or at what velocity it is supposed to be accurate, it's really not very useful in predicting long range results. At best, a single BC number is known to not be accurate over the range of a bullet's flight.
Many of the published BC numbers for Speer bullets appear to be over stated.
Possibly, they determined BC by modeling rather than by testing. Bullet manufacturers used to do it that way in the past until they expanded their ballistics capability. It's very expensive to do real world BC testing, but it's necessary, because the theoretically obtained BC values often differ dramatically from real world values.
I may have some of those bullets laying around here, and if I do I'll take a look at them, but it's not reasonable that an older basic hunting design would exceed the best contemporary VLD designs of the same weight.
If their BC numbers were accurate, LR shooters would be raving about the Speer miracle bullets and shooting them.
