Gentlemen,
Sometime back I was writing to a friend about loading some 270 Berger hunting VLD's and he mentioned that the hornady SST showed better specs than the Berger VLD's on the Ballistic Calculator. I didn't say anything but I didn't really agree either. Looking at the berger hunting VLD and the Hornady SST I just couldn't see that being true and wasn't sure how he came to that conclusion.
Well, tonight I got to looking at Hornady's specs online for loaded Superformance 270 140 gn SST amo. The specs hornady touts say's 3090 FPS at the muzzle will net you 2187 FPS and has 1487 Foot lbs at 500 yrds. I hadn't see a published BC for that round so I started plugging numbers into their own ballistic calculator. I used the 3090 for MV etc and tried different BC's till I came up with .494 which gave me the numbers they tout at 500 yrds.
Berger says the BC of their .277 Hunting VLD has a BC of .487 so now I see where my friend got the idea that the SST's have a higher BC.
Am I alone in thinking the Burgers look so much more streamlined and aerodynamic? Is Hornady actually correct on the BC? Any thoughts on this out there? Thanks, Terry
