Try googling Nosler Reloading Data. It's not your data, or my data, but it gives a non partial comparison to the cartridges with the loads listed from a company recognized for its integrity. Not your opinion vs my opinion vs ? opinion etc. that way.
Granted, I only looked at 180's & 200's, but the WSM beat the WinMag in both categories. Strange thing was, theirs wasn't built on a long action either..... Hmmmmm: im just not seeing any advantage whatsoever, let alone some mystical 200fps. sorry man. They're basically twins, & the edge goes to the WSM till you get to, or above 200gr bullets, where the WinMag starts to take over the lead due to case capacity alone.
Hey Edd, Nosler must've been issued the same magic wand we all got too. Wow
My Hornady manual puts them tied with more loads at the same speeds for the WSM till you get to 220gr bullets. Then the WinMag gets a 50 fps advantage over the WSM. Dang that magic wand went to Hornady too! But sadly, the mystical 200 fps never bothered to show up in favor of the WinMag.
Ok, enough being a smart a$$.
Lefty, I don't doubt your personal load data. Ive read quite a few of your posts, & i find you to be an honest member here with a good deal of knowledge. i respect that. Your also correct in assuming that I built my long action WSM the way I did to maximize its potential. However, Nosler, & Hornady didn't.
I know my personal load data to be true, so, These were just 2 examples of printed data from reputable company's in the business for a non bias view.
They're basically twins with the bullets i shoot, with the slight edge (very slight) going in favor of the WSM with those bullets, & less powder consumption. Plain & simple. Since I don't shoot Bergers I have no reason to want or need any more case capacity in a 30 cal. I'd rather just step up to a 338 than try and make my 300 into something it's not.
I still love the 300WinMag. I still plan on building one someday. But it's still basically a ballistic twin to my 300WSM that I already have.
The comparison of apples to oranges is one person talking bullets over 200 grains, & another person talking bullets up to 200gr. Even then it's a 50 fps difference with a 220 gr. in the Hornady load book. That's no where near 200 fps.
In fact, If that 50 fps is such an advantage, does that mean the WSM "blows the doors off" of the WinMag with the lighter 180's & 200's?
I doubt it. Realistically, they're so close ballistically that either can be loaded to have the upper hand untill you start launching super heavy for cal bullets. & like I said, at that point I'd rather just step up in caliber.
