I like the Ackley 40deg design on either the Whelan or 338/06. Feed just as well, never stretch, load mild load hot. I didn't "need it", I just enjoyed the whole nostalgia/messing with it thing, ha. My last factory Whelan was Mod 750 Carbine, It shot wonderfully so, just had wood so beautiful I never took it to the mountains, ha. sold it. My last Mod 700 classic ( that I used for 20ys as a WAI) got converted/rebarreled tot he 358 Norma Mag. Stomper of a round! Had to sell it. Now, my "one rifle" has morphed into "2", a Kimber 8400 300WSM and a new Kimber Hunter .270, ha. Go for it pard! enjoy yourself!
