Nothing too fascinating, but I shot my new 375 Wby DGR for about three hours today (60 rounds) in perfect weather -- 75-degrees, sunny, and no wind (literally).
Recoil was no problem with the 12-lb rifle.
How do you all measure your groups? From the outside/inside/middle of the bullet holes?
My good groups were within 3/4 inches measuring from the outside of the holes. Some were larger, but I am certain that that was due to user error.
I brought my new unused chrono, but did not set it up this time as it would have been difficult for the first time during the brief cease fires, and also a guy had one of those high-end Oehler Chronos and he let me shoot the 375 through it at the end of my extended range time. I only shot three of the 300gr NPs and two of the 260gr AB loads (I know more would be better, but I didn't want to impose on the guy). The Wby 300gr NP has a factgory listed muzzle velocity of 2,800fps, and the Nosler 260gr AB has a listed muzzle velocity of 3,000fps.
I assume the Oehler owner knows what he's talking about, but I thought I would double check with any experts out there because the numbers were higher than expected in a 24" barrel. The Oehler owner told me that the second column of numbers below is the one with the result. The printed results look like this:
For the 300gr NP:
For the 260gr AB:
Is Oehler guy correct?
If so, those are some pretty amazing numbers.
Obviously, the Wby NPs appear more erratic (or erotic) based on this small sample.
Thanks in advance any comments on what I should take away from that.
