Too bad you threw the flier at 2:00 o'clock

I preferred to be referred to as having a funny bone that is as screwed up as a football bat!

Long throated?

I think he posted .125" in another thread

Long throated?

But I'm jumping about .055

At 2.55 OAL I may be able to mag feed these...

@Nightraider are you single loading?

Do you by any chance have access to a LabRadar? It would be interesting to determine the G7 BC from the velocity drop data for comparison with the manufacturer's published value. In my hands, the G7 BC of pointed 90 VLDs typically run about 0.290. I have also played around a bit with the Hornady 88 ELDM, which I suspect has a very similar design to the 90 A-Tip. To my surprise, the 88 ELDM LabRadar velocity drop data routinely gave me a predicted G7 BC greater than 0.300, typically 0.302 to 0.305. It wouldn't surprise me if the 90 A-Tip was even higher. They look to be shooting quite well in your hands.
