6.5 143gn Bondstrike performance

Hey guys, Hey Guys,
Just wondering what people's experiences is with the 143gn Bondstrike are. I'm running them through two different guns with a bang on 100yard zero one is a 14in barrel running 2400fps and and the other 18in barrel running 2680fps. When verrifying at 350 yards they both run 4.5in high and at 450 8in high compared to the ballistic calculator(using AP and Hornady app), when I run the ELDX it's almost bang on at those ranges. So I'm thinking the Bondstrike performs much better than than it's stated bc. Has anyone else had the same experience with the bondstrike?

Mine were pretty much spot on with strelok.

Outstanding bullet out of my SAUM.

Just double check that you are using either the G1 or G7 BCs correctly. (i.e. using a g7 value as g1 bc would make a huge drag difference)

They kill well

Yea im using the correct bc value. I think I possibly got a bad speed reading as I had to replace the battery and I have read online that someone had a similar problem. According the the speed adjustment I'm putting in about 150fps to slow.
