Truing Berger 105 hybrid BC

[MvHTjy]

I'm trying to dial in my dope for next (regional) PRS season and was finally able to make it out to the range yesterday. I noticed when shooting further out my dope was off from my kestrel and things didn't line up until I set the G7 BC pretty high. My velocity seems accurate and lines up with what my Garmin is showing inside of 500-600. Has anyone else had to true their BC super high (.300+) for 105 hybrids?

Yep, I would be surprised if anyone here does not do this.

 

[MvHTjy]

Oh wow, alright. Just wanted to make sure something wasn't off, scope tracking or whatever. Thanks for confirming

I just follow directions that come with the Kestrel. Chronograph your load to get a good average. Imput the velocity data in the Kestrel.
The Kestrel gets all the environmental data loaded at your altitude, temperature, etc.
Set your target at 650 yds away with Your lazer range finder.
Shoot the manufacturers stated BC.
Adjust elevation to impact center of target at 650 yds. How does that elevation compare with the stated BC...adjust the BC value to match the impact value on the turrent. Then confirm at 1000yds, it should be right on.

Try the custom curves. Have been within .2 out to 1200M for me

Just tried custom curves and compared and it's off by half a mil @ 800. Guess I'll stick with BC...if it works, why bother changing it?

Something is wrong with your velocity or data or other equipment. There’s no way that the BC is north of .300. Have shot tens of thousands of 105 hybrids and have always run either the box BC of .275-278 or a G7 of .282- .283 if I was pointing bullets.

 

[morganlamprecht]

agree with sheldon...105 hybrids are always .275 +/- a few points

something is skewing things

Shoot center plate at 300, 400, and 500 to confirm your velocity is or isn’t correct.

That’s a known bullet, your other inputs will be the problem
