I've seen a growing following of these new Magnums offed by Winchester.
I always looked and saw very little performance gain over established calibers. Not enough to scrap the older proven magnums in my mind at first glance. I need to see where they real world out perform older calibers.
I fired my first ever WSM last weekend in a young gents BAR, he graciously let me try out. A lovely working Rifle, and with the 180gr Win BT's, I was impressed on the push, though a little hard, rather than the jolt of the 300WM. I watched him fire and observed the cyclic speed, noting it was much akin to a .308, rather than the slow- mo I've seen on BAR's with long action calibers, which it should in the short action.
This could be an ideal platform for the Short Mag if you are inclined to an auto and a 300 or 270.
Where is the gain over the 300WM in a bolt gun?
Really, would I park a 300 WM for one. I can see the first time purchaser, but what can it do the older cartridges can't?
I see the 270WSM mentioned in a M70 thread, over the 270Win going on 90years old. The 270WSM is faster with same bullet, no questions. But........
Both cartridges in the 130 XP3's from Winchester with the WSM starting out at around factory 7Rem Mag energies, the gap closes to a little over 200 ft-lbs at 500yds. It only shoots 2 inches flatter on a 250 yd zero at 400yds , and 1 inch less drift @ 10mph. Even with the 150gr BT's, which I thought the Mag would open up the field a bit ,theres only a small proportionate ballistic advantage. The energy gain drops to 199ft-lbs@500yds.
And this is compared to a Standard caliber.
Is there enough here to make me park my .270Win for the same featherweight in 270WSM, or even recommend it to a first time Featherweight buyer ,considering the tiny tiny ballistic gain versus the enormous amount more for ammo, if its avaliable at all in some areas. If theres centerfire on the shelf, theres 270 Win. The 270Win has many, many, more Factory loads to chose from, from econo to Premium loads.
What will keep these cartridges alive really? Will they ever repalce the established 270, 30-06, 7RemMag, 300WM????
Besides a Whitetail deer getting hit by 199ft-lbs of more energy at 500yds, and the old .270Win already possessing 1458ft-lbs, which is totally adequate, what does the 270 WSM give me in the field in real advantage terms???
My conclusion, trying to be objective and admittingly not being a fan of these WSM's is this,......If I wanted an autoloader like a BAR,.... I couldn't think of a better cartridges in 270 WSM and 300WSM. I've seen alot of hangups with the 270Win and even the 06 on the BAR platform, but in short action like 308, it seemed a lot more reliable, hence my conclusion that the Short Magnums should performing accordingly.
On Bolt guns unless theres an inheritant accuracy gain of a wide proportion over long actions like 270Win and 300WM, then I don't really see a gain or need here.
I like to hear the real world gain with the WSM's
