Has anyone load and shot 200gr in .300WSM?
How is performing, accuracy, velocity etc?

I have not shot it in mine, but I have seen other's reports. Accuracy and performance are generally good, but the consensus so far has been that the 200gr bullet consumes a good deal of case volume, and all things being equal, velocities are considerably down from say 300WM. However, if you are not after the speediest bullet in the woods, who cares? good luck

Speed is my least concern,
I long for accuracy and effective, ethical kill.
Velocities are good, but sometimes they create 'splash' factor and do more bad then good.

Still havent decide it which 300 MAGNUM caliber to buy

I've been working with 200 gr. Partitions in a 300 WSM.
The rifle is a Savage 12 VBSS. 26" barrel.

My most accurate loads are in the 62 to 63 gr. range with Reloader 19. (1/2" at 100 yds.) Norma brass and Fed. 210M primers were used.

I set OAL to the lands. Loads start to compress at 64.5 gr. and start getting high pressure signs at 66 gr.

I also got good results useing Winchester 180 gr. Power Points, Tubal 7000 @ 61.5 gr. Fed 210 primers and Winchester brass.

Both are hunting loads.

I don't have a crony so I can't clock them.

There is no problem whatsoever with any loss in case capacity in the WSM for any bullet length up through the 220 gr Nosler partition.

There is plenty of capacity in this case to make 2944 fps with 67 grs of R22 and the 200 gr Nosler Partition...quite a long bullet (Nosler RG 5th ED). I use R25 with Hornady 220s to make 2720 fps in a 24 inch bbl....no problem.

There is no majic to this....just good case design. As bullet weight goes up, you need less powder to make the same energy, so there is more room for bullet intrusion. In a good case, this balances out and in a GREAT case, energy remains constant but load density goes DOWN as the bullet weight goes up.
