Quote: Not trying to bore anybody, but the specs on the ultra lightweight 500 Jeffery are as follows. Stainless steel winchester control feed action, 16" shilen barrel, stainless steel 1/4 rib, banded front sight, grey wood laminated stock, dual cross bolts, shoots 570 grain Barnes bullets at 2200 ft./sec. for 6100 ft.lbs. 7" drop at 200 yards. On A.R. find " Grizzinator" for picture. Thats what Safari Kid named the gun when he originally had it made.
My 22 lr Winchester 69A without scope, but with factory receiver sight, weighs 5.8 pounds. Aside from the recoil question, I would find it very difficult to aim such a light rifle if I were breathing heavily from running to reach a shooting position, which happened to me on several occasions in Africa.
Frederick Courtney Selous mentioned acquiring a lifelong flinch from shooting a heavy recoiling black powder bore rifle. Using such a ridiculously light rifle in such a heavy caliber could well have the same effect. My .505 SRE wildcat develops virtually the same ballistics as the .500 Jeffery load just mentioned, and it weighs in at a modest 8.75 pounds. I would not care to reduce the weight at all.
In my younger years, I carried my 8+ pound M14 rifle 50 miles on a march starting at 8:00 on Friday morning and ending at 10:00 the next day, and the weight of the rifle was the least of my worries.
