Have a buddy offering a sporterized Enfield chambered in 300 Weatherby. My first thought was that a 300 weatherby was too much power for a Enfield. Thoughts or opinions welcome.

This was the listing:
This Eddystone (subsidiary of Remington) made Enfield 1917 (P17) is in a custom Bishop/Fajen stock. It has beautiful figuring in the butt-stock and it has a beautiful tiger maple end cap. The barrel is floated. I modified the bolt to Cock-on-Open over the original Cock-on-Close. I have the original firing pin to return to Cock-on-Close. The scope is original Weaver K6. The is normal wear around the top of the receiver on the left and right side around the ejection port. There is some light handling marks on the stock. There is no travel to the trigger just a 3-5lb pull and it breaks clean and crisp. I have added quick detach sling swivels, just push a button and they’re out. The barrel is 26” long and the magazine holds 4+1 in the tube.

M17 plenty strong enough. Many mags built on them. Conversion back to COC will require a new bolt or a weld-up re-harden, as the bolt has to be modified for the conversion.

I’ve seen numerous dangerous game guns done on the 1917. It’s a strong action and long enough.

I’ve shot a .450 Watts made on one, and seen a .416 Rigby one.

No concerns with a .300 magnum.

Do not confuse the P17 Enfield with the Lee Enfield in any of it's various forms.

There is no way a 300 Weatherby will fit on a Lee Enfield, and no one would ever do that, so that is not a concern.
As for cock on opening, I have seen plenty of conversions that did not alter the bolt. They just use the retracting cam to cock it; and a strong mainspring. I personally never convert them, because there is nothing broken about cock on closing; just that American shooters do not understand it nor know how to use it.
As to your question, it will be fine. I've done a ton of them in 375 H&H; actually more P14s because the bolt face and extractor don't need any modification.

For interest's sake, here is a bit of testing and fooling around with a Lee Enfield chambered in .300 Win Mag:

Not something I would do myself.

Very cool video and test.

Thanks

The Bloke (and his colleague the Chap) gets into the weeds on some interesting topics from time to time.

I dont think he's referring to a lee ...... I think he's asking about a 1917......

And its big enough and strong enough for about any "sporting rifle" cartridge.

Mr Connan is indeed referring to a Lee.
Of course, the OP is not, and he said it was a P17 up front.

Peter, thank you for that link. Astonishing what the test did and did not show.

Ive seen a 500 Jefferys and a 505 Gibbs IMP I owned once on a drop box -17 enfield sporter..Recoil sent her to the gun show on one and to the internet on the other...

Only done a couple P 17's Anyone have opnions /experience with the Traister cock on opening conversion?

They seem to work, I shot and seen a bunch of them on safari in various big bores, beautiful guns and my choice for the big bores..I shot a 505 Gibbs Imp at one time, all cocked on the opening and would not use cock on the closing that pushes the gun away from you when the chips are down as I've seen that happen on occasions under light stress of the need for quick follow up shots of escaping animals..A good Enfield custom is hard to beat and best of the bigbore conversions IMO

I've done two COA conversions. The conversion is quite simply done, comes with instructions and a replacement main spring. My opinion is the replacement spring could be more powerful, although no misfires where ever encountered.

Not to confuse the P14 (303) with the M17 (30.06) two different rifles.

If gunsmithing for a large Magnum case then use an M17 action for it's length and a P14 bolt which is already opened up for a magnum case head.

Surely if a P17 action is longer, the P14's bolt won't fit?

The P-14 and 1917 actions are the same except for magazine opening, the bolt face, extractor and the face of the barrel. Bolts are the same length and are identical except for the blot face. Triggers, bolt stops, safeties and action screws are identical and sometimes the bottom metal interchanges.

The 1917 is a modification of the p-14 to adapt it to work with the .30-06 cartridge.

We've done 550 Giggs, 550 Mag, 550 Express, 500 wells/a2, 500 Jeffe, and 500 Accrel on the action, 505 Gibbs is a "common" caliber on the action ..

reserve the puny 300 for a springfield

Yes sir Jeffe tell'em how it is! spot on, the world is your oyster with a P-17 even Win and Rem figured that out!
