No, the only thing they have in common is the diameter of the mouth of the brass. The entire rest of the cartridge is different.
Im sitting on 40 of em, 33 still factory loaded by winchester. No use for em. Does that make me rich!? Lol
Seems like with the micro/mini actions gaining popularity in the market and the continued growth of the AR platform the WSSM's should be gaining traction.
A super lightweight bolt gun in a WSSM seems like it'd be popular in theory.
Have they tried making a 6.5 WSSM? Maybe a 6.5 Creedmoor Super Short Magnum re-branding would turn it around!
Edited to add:
Actually, looking into it... I'd bet a 6.5 WSSM with decent factory support would take off. It has pretty similar ballistics to the 6.5Creed and fits in an AR15. If brass was available (and affordable) I'd be interested in one more than I'm already interested in either a 6.5 Creed or a 6.5 Grendel. If they could get factory ammo as prevalent as 6.5Creed was at its roll-out they'd sell all they could make.
No, not really.
I rebarrelled a Browning A-Bolt II in .223 WSSM to 6,5 WSSM. Any bullet longer than 120 grain takes up powder space. So do the 120's to a degree as they extend deeper than the base of the neck. This is because they are limited in over all length. With the length of the 5.56 / .223 at 2.260" and the .243 WSSM at 2.3598", there is no room for seating the bullets shallower.
My reasoning for my rifle was to achieve 6.5x55 ballistics in a short, compact rifle. It just barely gets there, but due to the short, stubby cartridge, can have feeding issues with pointed bullets like the Lapua Scenar and Bergers.
Oh, by the way, don't think that all the WSSM cases can be used interchangably. I tried using .25 WSSM cases but the shoulder angles between the .243 and .25 WSSM's are different enough that the .25's won't fireform unless they are near maximum charges. I refuse to do that with an experimental round in an unknown rifle and without sophiusticated pressure measuring equipment. I had 100 .25 WSSM cases necked up to .264 that I discarded because I was getting flattened primers before the shoulder was blown to the correct angle.
.243 WSSM shoulder angle = 28 degrees; .223 WSSM = 35 degrees; .25 WSSM = 30 degrees.
I hope this is helpful.
If you load 'em hot or fire factory ammo only, yes, they are.
BTW, I have an unfired .223 WSSM barrel off of a Browning A-bolt II if anyone is interested.
So if you were not full case fire forming with one shot, you were not there yet, keep at it, you will get there. Sometimes my 445 Super Mag takes three firings of the 30-40 Kraig cases.
I currently have several hundred new 243WSSM Fed. cases listed for sale or trade: https://www.thehighroad.org/index.php?threads/fs-243wssm-375-h-h-lc-30-06-brass-garand-clips-snipepod-bipod-texas.885088/ (Also have 90 or so WW cases FS/FT but did not list them.)
The WW cases are definately harder than the Fed. Never split either, but those that I loaded were for one rifle. I did prefer the Fed. as they were easier to resize, having less "spring back".
The 243WSSM can be hard on barrels if pushed, but I fired around 300 mild rounds (3000 to 3100 fps ) of 100 gr NSB my go to Dtech for predator and WT doe culling. I did not measure the throat, however, but bore showed no visible wear w/a bore scope.
Believe the picture is an old one, based on price, and I also tried to log on to address but never was able to do so??
