I hopped on the bandwagon and shoot a Winchester Model 70 Featherweight in .300 WSM. I doubt if any game can tell the cartridge is a little shorter than say a .300 Win. Mag. or .300 H&H.
Where I live in the Pennsylvania/New York area I was a die hard .270 Win. shooter until I deflected a bullet or two and completely missed two deer. Thankfully, they were complete misses. Now, I’m having a good run of luck using a circa-1941 Savage Model 99 in .300 Savage. That cartridge is perhaps the original short mag. The Model 99 is scoped, so on really bad weather days I go to my back-up gun, a rather battered Marlin Glenfield Model 30 in .30-30 Win. Prior to antler restrictions, that was my Pennsylvania deer and bear rig, complete with open sights.
So there you have it—a scoped Savage Model 99 in .300 Savage backed up by an open-sighted Marlin lever gun in .30-30 Win. I’m currently looking for another Savage Model 99, but in .250 Savage.—Jeff R.
