300WSM in AR10 Platform?

[Spcamno]

Don't want to derail the other thread and will start the discussion here on modifying AR10 Platform to wsm caliber








I only have a 300wsm snap cap to demonstrate the length (shot my last box of wsm last season) pics to compare 300wsm length to 150gr Remmy core-lokt 308, the 300wsm is actually shorter but bulkier.

Updated: more pics at post #8

The 300 wsm case web has been linked to case head separations in ar platforms. The rsaum is a much better candidate as the web is stronger. I'd own either of them if jp made a wsm bolt for the ar 10

Actuallly KAK make one for DPMS

www.kakindustry.com/magnum/kak-industry-bcg-mag

Not good enough?

I wouldn't trust it. Jp has a proven track record for making the best 6.5 grendel bolt where others fail. Atrs has put thousands of rounds through their 3 gun grendel without a failure. Others grendel bolts break.

Interesting info.

What about just open up the existing stag bolt?

Know it has been done before.

Maybe this will void the warranty? Kidding.
Don't sounds very safe to remove material and add pressure.

I have the opportunity to try some factory Winchester 180gr sp 300wsm in a 308win pistol mag (XCR-M mag) and it fits right it and appears it should feed through the mag no problem.

We're just missing a proper bolt.

KAK don't ship to Canada.

Depending on what you after it may be easier (and cheaper) just to do a barrel swap to 338 Federal or 375 Raptor if you want more power unless you must have a 300wsm.

Or .358win. But none of them really extend the hunting effective range (3-400m) of the .308win.
And 6.5cd ain't much for moose or bear.
That's the "need" for a .300wsm or .300rsaum. But until it's readily available I have a good reason not to spend money!

Very true and that's the reason why I am interested.

However, from what I have found so far is the reliability on the kak bolt is questionable and I have yet to find another bolt maker that offers ar10 bolt in magnum bolt face.
