Thread: Trying to understand Barnes LRX BC

I had 15 of the 6.5mm 127gr LRX arrive by courier from Gunworks, along with the same quantity 130gr Swift Scirocco's, just to have a play with in my 6.5mm SAUM.

First thing that struck me with the Barnes was the length - these are a looong bullet (obviously due to all copper construction). I measured with my digital vernier, they are 1.4 inches in length. They are longer than the Swift's. They actually look like a half decent projectile - boat tail is quite long (I guess close to a Berger VLD maybe?) However from what i've read Barnes calculate their BC values at 300 yards (0.468).

Would it be fair to assume that their BC value when measured the same as other manufacturers bullets of the same shape / weight would be around the 0.550 mark? - the Scirocco's are .561

Cheers,

Michael.
