Early Scopes
Stoeger’s 1932 catalog showcased “Rifle Telescopes for Hunting” from
Zeiss and Hensoldt, including the variable Zeiss 1X-4X as well as
Hensholdt’s Luxor-Hell with “unsurpassed brilliance.” The Luxor-Hell was
longer than a Coney Island hot dog and weighed a full pound with a
narrow 100-yard 11-foot field of view. It cost $45.00 when a Winchester
Model 94 sold for $36.30.
Acceptance Finally
By the late 1940s, and especially 1950s, the scope sight was poised for
a takeover. Pete Kuhlhoff, guns editor for Argosy, one of America’s
best-selling magazines in the ‘50s, noted in Kuhlhoff on Guns,
“Regardless of the kind of shooting — be it plinking, small-game
hunting, varmint hunting, big game hunting or target shooting — the
scope sight is of tremendous help in accurate aiming.” He advised 2.5X
to 4X for big game.
Getting Serious
When tags remain unfilled toward the end of a big game season, I put
away all my “toys” and get serious. Serious means Mr. Clean Sweep, a
Morrison Precision custom .30-‘06 that makes witnessed half-inch
clusters at 100 yards with 21st century “magnumized” ammo — Federal’s
powerful High Energy 180-grain bullet at former .300 H&H factory punch,
as well as a special handload from Barnes Reloading Manual 3, page 358,
a 180-grain bullet at 3,000 feet per second chronographed from the 26-
inch barrel.
The great accuracy and strong arrival energy at long range prompted a
scope to match this rifle’s potential: Swarovksi 2X-12X Z6i, a
remarkable achievement in 21st century optical development with
incredible target resolution. Magnification runs 2X black timber/brush
to 12X long range bullet placement, remarkable in one scope. The
investment price pays off in years of big game success.
A pen pal and I carry on a friendly disagreement. He claims the
American big game hunter is “over-scoped.” He chooses a 2.5X fixed power
scope over a variable for all big game hunting. I say no way. Today’s
infallible variable is the king of scopes, ready for close-up at low
power with no argument superiority for placing bullets spot-on far off.
The Z6i on Mr. Clean Sweep, for example, serves in black timber for elk
at lower magnification, antelope on the plains on higher power. Another
friend goes 6X for all big game. I suggest he buy a variable, set it on
6X, and then try to convince himself that 6X is best on a whitetail
breaking cover at 32 paces and a mule deer buck across a Rocky Mountain
canyon at 278 yards.
At this point we could go into all sorts of technical jargon from the
world of optical science. I get a chuckle when I read some of that stuff
in gun magazines. I dare the writer to truly explain those big
scientific words used by lads and lassies who hold PhDs in physics.
Those of us who prefer results over big words consider optical
resolution, eye relief, focus, accurate point of impact movement, and
ruggedness.
A riflescope is obviously an optical instrument and as such I want it to
resolve images, a trait that separates the great big game scopes in the
field from the also-rans. I want to clearly "make out” the target in
every type of hunting niche. You mean you can’t tell that’s a bull moose
in your scope? I can. But how about the branch running parallel to its
chest? Can I make that out in shadowy timber? Can I see that one clear
hole through the foliage that leads to a perfect shot? That happens only
with scopes of high optical resolution. |
