50cal WSM

[7ultra]

Just floating this idea, just want to know if it is even possible. Could one take a WSM case and blow it out to accept 50cal BMG bullets. Designed intent would be to dublicate the performance of a 50 cal Whisper, but do so in a more economical package. Again, just wondering If it would fly (biggest problem seems to be the shoulder, or lack thereof) thanks

7Ultra,

I have looked into using the RUM case blown out and necked up to .510" but never felt comfortable enough with the small shoulder, even with a max blown out case to try it.

The WSM will have considerably less powder capacity then the Whisper and it used the big Wby hulls. Still the 500 Whisper is designed to work at 1050 fps and I would think the WSM case could provide that with top loads.

Still, the shoulder issue will be a concern.

A better case would be the Lazzeroni Short Magnum case as it is basically the same capacity but in a bit shorter and even fatter case.

I personally do not care for the quality of Lazzeroni brass so this is why I would not go that direction but it would provide a more positive shoulder, especially if sharpened up to 40 degrees or so.

Also, at the price of the Lazzeroni brass, the big Wby hulls are cheaper by a fair margin and much better in quality in my opinion.

Goog Shooting!!

the 50 on the 460wby case is the peacekeeper, not the whisper isnt it? and well capable of about 3/4 of a BMG in performance from the numbers i've seen.

2400 with a 750amax IIRC.

what case is the whisper on anyway? short 460wby?

The Peacekeeper is basically a 500 A-Square throated to accept the long 50 BMG bullets.

It is built on the full length 460 Wby case.

The 500 Whisper is also built on that same case but is shortened to I believe a bit under 2" in case length but I do not have the exact length in front of me right now.

It is true the 50 PK is a great round but at extreme range the 50 BMG is still the king of the 50's by a fair margin.

Considering the savings in powder for the PK compared to the spendier brass of the PK and I would rather have the 50 BMG if your looking for a high performance 50 cal round.

Recoil of the PK in typical weight rifles is nearly identical to the 50 BMG in their 30 lb rifles, just less performance.

There was alot of fuss about the PK when it came out but the interest has since died off, especially with the idea of the 408 class rounds coming out.

Good Shooting!!

The 500 Jeffery case has a smaller rim diameter than the big Weatherby or Rigby cases, (slightly larger than the WSM) it has more water capacity and is shorter ta boot... a good choice, with Horneber brass.

I wouldn't trust the little itsy-bitsy shoulder that would be left with a 510/300 WSM... if you could even call it a shoulder.

Economical being cheaper brass, it don't get much better than the big Weatherby stuff for $2.00 each, well, besides surplus 50 BMG ammo.
