I have been given a Wby Mark 5 (Japan) in .300 Wby and am considering a rebarrel (do not need another .300) opening the floor for suggestions.

Looking to keep things simple.

Thanks,

Keeping it simple would be to rebarrel to a 340 since you don't want another 300. You can go smaller but the bolt travel is longer in the "full length cartridges".

Ken....

375 H&H or Wby, 8mm Rem Mag, 416 Rem, 458 Lott. I hate to see longer actions wasting length!

.257 Weatherby, .270 Weatherby, 7mm Weatherby, or 7mm Remington Mag should fit with little or no problems.

Either the 340 WBY or the 375 WBY would be my choice.

With the 375 WBY you can shoot 375 H&H's if necessary.

I am thinking the very same thing, but in addition to the 340 and 375 WBY, I am thinking about the 358 STA. Is the taper and other case dimensions close enough so that I wouldn't need to mess with the follower and feed rails. I want to simple screw a new barrel on to my M70 Classic Sporter in 300 WBY. Lou

Dr. Lou my list is drop-in fit conversions. I was not sure if a 340 Wby was based on the 300 Wby case or the 378 Wby case (not a drop-in).

If the 358 STA is based on a necked down 375 H&H it should be fine even if in "Improved", straighter walled case config such as the 300 Wby and 375 Wby.

Airgun, thanks for the info. I like the 340 and 375 WBY, but the 358 STA has always fascinated me. It's based on the 8mm Rem. Lou
