[QUOTE="FlyGuy11, post: 1914880, member: 108987"] This shows me that we all have been quarantined too longo_O This is just my $.02 on the subject. Benchrest shooters use short, fat cartridges with higher shoulder angle for "higher efficiency" and P.O. Ackley used it for the same as well as longer case life. The WSMs were developed based on the efficiency logic gained from benchrest shooters (maybe a little PO Ackley influence). I have personally found that a reloader selecting the right bullet and powder for the best result is the best solution. I have a 280 AI and it will get a berger hunting 168gr to 2952 fps (25" barrel 1in9") with Reloader 26. I can equal or kick a 7mm Rem Mags butt 168 gr and below bullets. Raise the bullet weight to 175gr or 180gr the 7mm Rem Mag kicks my 280 AI's butt. How I select a cartridge is based on desired energy at a desired range with reasonable wind drift. What do I know I drank some Kool-Aid and bought a 28 Nosler rifle for Elk hunting. Zero to 900 yards I don't worry about efficiency due to considering this a dedicated low round count purpose hunting rifle. And my Kool-Aid tastes great. [/QUOTE]
