Beladran....
Like Possum,I, to did a lot of reseach before buying,at many of the same websites...
The main reason I settled for the Whelan was availbilty,H&R doesn't make a 358 Winchester at this time(what I REALLY wanted),nor do they make a 375 Winchester either.The only way I could have got these is by buying a Encore.Which I wasn't interested in REALLY doing.Or a Build on a H&R,that would have cost a small fortune.
The recoil isn't any worse than a 30-06( I have two)a Savage and a Marlin.I like the round enough that I'm seriously looking into a rebarrel to the Whelan on one of the actions,most likely the Savage,the Marlin is just a plain flat out tack driver,so I am little leery of messy with it(might never get it to shot the same if it's fooled with).
As far as it killing Grizzlies,it can,but then agin in a pinch so can a 30-06,I have a cousin that lives in Alaska,he's killed 2 with a 06".
As far as performace, why waste that amount of powder in a long case for 444 or 45-70,when the Whelan is a way better round in killing power.
I, too really don't need to shot 300 or 400 yards to deer hunt,but I do like calibers,that if I need to, I can.Example 30-06,308,7mm08,these can and will reach out and touch em' if need be,lol
