Re: 338 Swift bullets
FYI concerning your last question...this is my experience with the (granted) 30 cal:
Randomly selected (.444 BC) 30 cal 200g Swift A-frames varied as much as 4/10 of a grain from 200g. Randomly selected (.588 BC) 200g 30 cal Nosler Accubonds varied by 1/10 g at most from 200g. Bullet lengths measured with Sinclair bullet comparator could be different by several thousandths with the A-frames. Every one of the Nosler Accubonds I measured with the bullet comparator were EXACTLY the same. If you want consistent bullet seating to be a certain distance from the lands, this could be an issue. With 1.44 difference in BC between these bullets (I don't recall the numbers for the .338 cal), past 400 or 500 yds, I would think the Accubond would be holding a ballistic edge (bullet drop, retained energy).
