Re: drop chart and chronograph drop chart
The Berger BC is almost rock solid and I would not touch it but look elsewhere. The HSM ammo I've ran out has been very close to published specs, I would be very suspicious if I had to tune it as much as you have but it could be possible. If it seems like your of about the same MOA through out the range but have to tune the velocity beyond what it should be then look at your turret adjustment value.
I set up a rifle and scope last week that was showing low at every range out to 1435, I could tune it up to be on out to about 1000yrds with velocity but then at 1435 it was not on, took everything back to the velocity I thought it should be, which the crony told me it was and tweaked my turret adjustment just .020 and ALL ranges to 1435 were spot on, not a little high then a little low but dead nuts on!!
