I just came into this M7 in 300 RSAUM. Ammo is just about non-existant or priced crazy & I do not reload! Is there ANYTHING I can have this rifle rechammered to?? I am trying to avoid the expense of rebarreling. ANY suggestions would be greatly appreciated!

I think the saum case is just slightly shorter than the .300wsm case. I wonder if it is a simple rechamber to get the rifle made into a .300wsm?

I think the magazine is just a tad too short for the .300 WSM, which is the only thing you might rechamber for. I've seen magazines lengthened on regular short action Remington M700's, but I'm not sure if there is any way to do it on the more compact M7.

The short magazine doesn't leave you many choices in standard factory cartridges even if you go to the expense of rebarreling, either. I suppose you might squeeze the 6.5 Rem Mag into it, but ammunition would be equally scarce and about as expensive.

If you want to just sit on it for about another 50 years, I'm sure it will be as scarce as an original .30 Newton and might bring you a modest profit. Otherwise, I just can't think of any economical solutions.

Just looked up the specs for each cartridge and the .300 WSM has virtually the same OAL as the .300 SAUM. I'd say it is entirely possible that the WSM would work in your M7.

Whether the small (if any) reduction in ammunition cost would ever pay for the conversion is another matter. At least the WSM ammunition is more widely available.

you'd have to have the feed rails worked over and maybe the bolt face.
sounds like the perfect reason to start reloading.
or find someone that does.
at least you have the 30 it'll probably be easier to find brass for it than the 7mm version.

The feed rails and bolt face will require no modification. The only real difference in the 2 cases is datum length.

Tim50, any photos of the rifle?

I would take up reloading. The SAUM is an easy cartridge to reload for.I have not seen a 300SAUM that does not shoot and generaly better than the WSM. The WSM case is longer than the 300SAUM so could be a feeding issue in the M7 which has a shorter mag than the M700.

Yes the COAL is the same but with the longer case the cartridge may well have to come out of the mag at a steep angle??

The caliber is a good one, so just sell or trade for what you want. The saum's are doing very well shooting long range. Or, buy some dies and start reloading. That caliber is typically very accurate and easy to shoot. You will have all kinds of trouble and expense re-barreling.

Very good recommendation.
