Now that my tax refund is in the bank, a new rifle is in my radar, and I'd like to ask those who own the Savage Model 16 in 300 WSM, "How do like it? " Does it feed cartridges smoothly? Is it accurate with hand loads? Is the magazine length sufficient to allow seating the bullet close to touching the lands? How does the recoil compare to a 300 Win Mag? I plan to use the rifle for elk, black bear, and deer at longer ranges, say up to 500 yards.
.............Can`t really offer anything regarding the Savage rifle, but do have a 300 WSM and did own a 300 Win for many years.
You may have to fully size your casings to avoid feeding issues, because the 35 degree shoulder casings hung up when I tried to chamber partially sized cases. After switching over to fully sizing all my cases, I`ve never had any feeding problems since. Very smooth!
As far as accuracy goes, no reason why the 300 WSM can`t be as accurate as any other 300 mag. The best accuracy with your handloads, will largely depend upon what particular components in bullets and powders your individual rifle likes.
My rifle`s magazine length is 2.900"..To determine best accuracy for any given "hunting" load, I started with the max COAL that the magazine could handle while still cycling the bolt effectively. Then I reduced the COAL by 10 or 15/1000ths to best determine what bullet jump my rifle liked for accuracy. This process should be done regardless of what bullet and/or bullet weight you use.
If you can handle a 300 Win, you should be able to handle the 300 WSM`s recoil as well.
For the game you list above, out to 500 yards is no problem for a 300 WSM. The 300 WSM according to Lyman, given the same barrel length, runs on average, about 30 to 50 fps behind a 300 Win. With heavier 200 gr bullets maybe 50 to 100 fps behind. There are no real meaningful killing difference on any game between these two.
