I've been reading up on some of the short mags lately, trying to make myself like them. Interesting stuff, some of it. Like the article I read where Charlie Sisk chambered a barrel for the 300wsm, worked up some loads and chronoed them. Then cut the shank off and rechambered the same barrel to 300 H&H. Shooting the same charge of the same powder under the same bullet showed identicle speeds at lower pressure. But ask anyone off the street about the ol' SuperThirty and they'll tell you " aw heck with modern powders you can pretty much get the same performance out of the 06. Which is close to true, and yet the wsm is a magnum powerhouse. I know you can't get wsm speeds from the 06 case, but you can get pretty close.
Then we have the 325Wsm, which I like the most of that family of cartridges and have seen in action many times. I know it works and works well, but some of the speeds folks are posting with 200gr bullets make me wonder. I can drive a 200 to the same speeds from my Whelen. I know it has a larger expansion ratio and all but, it uses substatially less powder to acheive the same speed. The BC and SD numbers aren't quite as good, but honestly how much do they matter to most of us in a normal days hunting?
Makes me wonder if we are underrating the old 06 case or if maybe I'm just crazy and missing something. Just seems like people like to chose odd times and places to place great importance on 100fps.
Just my thoughts.
