Rebarelling

[bob_dobalina]

I found this online:

Short actions with a bolt face .Dia of .540+/-
223 WSSM, 243 WSSM, 25 WSSM, 7mm Rem saum, 7mm WSM, 300 Rem saum, 300
WSM, 325 WSM, and the 350 Rem Mag.

Does this mean any of these can be re-barreled to the other and adjusted to proper headspace, with maybe a new magazine and that is it - or is there more to it than that? Like could I take an 25 wssm and easily re-barrel to a 300 wsm?

thanks

This is the diameter of the bolt face. All of those cartridges will fit that action. Depending on overall cartridge length will depend on your magazine length. You have 3 major bolt face classifications .223 I can't remember the diameter off the top of my head, your .478 which is standard for like .243, .308, .270, .280 etc then your magnum bolt face which will cover your short mags in a short action or your belted magnum rounds in a long action. So yes but you also would have to buy a new barrel in that diameter. Other than that you are on the right track.

It's .378 for .223 class, .473 for the .308/.30-06 class, and .532 for the standard magnums. Then you have PPC/220 russian based cases (pretty sure it's .441) and .338 Lapua/.378 Weatherby .587.

As long as the action is for the same length cartridge or longer it is usually pretty easy to rebarrel. Changing a WSSM into a WSM might require a different follower/mag box because of the case length difference but that is generally pretty easy.

I'm not sure, but I think the WSSM actions from Browning and Winnie (the only folks who made them until the AR guys discovered the darn things will fit and feed in that platform) are actually shorter than the standard short action (308Win/300WSM length). I may be wrong, but there are different bases for the WSSM actions, I think. Working totally off of memory here, so don't crucify the old guy if he's wrong, you know!
