These days I kill a lot of steel from 850 to 1000 every month. May through October... 1000 yard bench rest silhouette is my game.
I shoot two classes of rifles a 12 and 17 pound.
Running everything from a 6mm BRA. To a 300 SAUM.
This takes up most of my shooting efforts these days.
But 35 years ago.
I did alot of wood chuck hunting.
Back then it was pretty much all I did.
My first custom was built by Nelson Berger.Of marshallsville Ohio.
A 22 CHeetah on a 40x action.
I made those little buggers pay.
Running the Slow 1-16 twist and 52g Bergers I found it very effective out to 500 And I think my longest was right around 550.
Later I built a second CHeetah a much different set up built by Clarence Hammond of Red Lion PA.
This rifle was a full on BR rifle Stolle action McMillian BR stock and a Lilja 28 inch bull barrel. 1-15 twist.
I shot piles of chucks and did very well from 350 to 550.
One evening I pulled out my 1936 German Army
Barr and Stroud 250 meter baseline range finder... Yes the Brits sold them to Germany before the war .
660 yards is what it worked out to.
Not supposed to be able to get those light bullets to do that kind of stuff. But back then I didn't know what I didn't know..
These days if I had a peskie chuck that needed a bullet.
I'd just dig out a bench gun and letum have it.
Might use a Lazer
So do you remember when Hammond had a camp in Keating, and ran an airboat on the west branch of the Susquehanna river and the Sinnemahoning creek as far as Sinnemahoning during the buck season hunting the hillsides?
As for the Germans having Barr&Stroud rangefinders, i dont doubt they had some, and so did the Japs, but the Germans had very good ones of their own as well. Not all of them were usable however, as those were used for a specific purpose.
I still have and use a Wild rangefinder quite often, and consider it a bit better than the Barr&Stroud.
They never refuse to work when conditions are poor.
