Just thinking out load.- looking for your thoughts

Looking at the new .25 WSSM and thinking about what one would be like in 6.5mm.

There are enough .223 or .243 burnt out WSSM's out here or soon will be.
What do you think one built on a 6.5 cal wouuld be like??

About like a 260 Remington.

It's been done. One version is a simple neck-up job and has already been used in both 1000 yard BR and in F Class. It's called the 6.5 Fat Cat. I'm sure there are other versions and names. And yes, it works great.

The 25 WSSM case has comparable capacity to a 2506, so it ought to be more like a 6.5 x 06 than a 260 Remington. While being an inch shorter than either the 2506 or the 6.506, the shorter case ought to make it work as well or better than the the 6.5 x 284 in short actions because the 25 WSSM is 1/2 inch shorter than the 284 case, with the same case capacity, allowing bullets to be seater out a 1/2 inch farther for the same magazine length to take up less powder space...Rusty.

I'd take one. Not very classy, but I bet it would perform.

i'll ask...

with the 25wssm available, in hand, (which is actually closer to 6.5MM than then .264 which is 6.7mm) ...
you would spend
150 for a reamer
175 for dies
30 for headpsace gages
180 for a barrel.

or about $650 bucks, with no gunsmithing charges added in, for .007" of an inch?

that's one sheet of paper, wrapped around a .257 bullet.


btw, $650/.007" = 92857 dollars per inch

Very neat analogy, Jeffe. What makes the .257 to .264 an apples to oranges comparison(contrast), is the lack of heavier bullets and facilitating twist in the .257.

The 6.5 X 55, as modest as it is, jumps into the Elk and Moose catagory when loaded with superb SD 160gr. bullet.Not so with any 25 caliber that I know of. Now, if there were a proportional 25 cal bullet of 148gr.and a rifle having an 8.5 twist your .007" difference in dia.scenario really makes sense. roger

Roger,
hornady used to make a 140 or 145gr 257 bullet, that would stabilize in a 1x9, iirc...

the last surplus of them I saw was about 5 years ago, from huntington's or some such, that died do to lack of interest...



shot fine in my 257 roberts, btw

I spend that much on my standard caliber rifle barrels! Not to mention the pickup truck needed to haul everything to the range.

Being chrome lined, I don't think that there will be nearly as many burned out 223 and 243 WSSM barrels are some folks seem to think.

Even if the 6.5 WSSM will handle heavier bullets than the 25 WSSM, which handles bullets up to 120 grain damned well, OAL will be an issue if you want a magazine fed repeating rifle. If you look at BC and SD numbers, the .264" bullets don't show much advantage over the .257" bullets until they get significantly longer and heavier. Significantly longer bullets are going to need to be seated more deeply into the case and will replace some powder capacity and, therefore, some velocity potential. I think that I'll stick to my 260, 6.5-284, and 256 Newton rifle in 6.5mm.

I think that I would build a 6.5 Norma before the 6.5WSSM.
