Difference between P14 and M17

maroontoad · 05-08-2007, 09:46 PM

Apart from the obvious bolt face and magazine dimensions, what are the other differences?
Are the receiver rings and threads the same or different?
How about sights? Have they been graduated for the different trajectories?

I have an unchambered barrel which is threaded for a P14 with the intention of chambering it for 303/.25. While a good caliber, that doesn't offer much variety and it started me wondering if I couldn't screw it into a M17 and chamber it for .25-06, .25 Souper, .250-3000 or even .257 Roberts.

Thanks for looking.

don't give up on the 303/25 especially if its 1:10 twist barrel.

A 1:12 won't do for anything above 87grainers with any sort of accuracy but a 1:10 will throw 60gn pills or 120s and anything in between.

Very effective round

Sorry mate don't know if the p14 gear fits a p17

Personaly I'd keep the 303/25 idea going especially if you've got a 1:10 twist barrel there. It's an awesome round, used a lot down my way during the 70s before it was discontinued. BTW if you have any necked down cases that you don't end up needing. I'll happily take em off you hands

Snow,
Back in 1958 I had Bill Gallagher build me a .303/25 using an M17 action and a Bohler barrel. It was rubbish. I went back to using a full stocked SMLE, lighter and I actually hit the occasional pig or roo with it.
I had a mate with a.257 Roberts, built on an old Mauser 98 action and it was very good. You'd have to think that way, as ..303 brass would be much harder to come by than .308 (7.62nato).
Good luck.

The received wisdom is that you will find more differences between the manufactures than just the calibre difference. In other words don't expect to interchange parts between a Winchester and a Remington.

The whole reason for having the US 1917 rifle was to use P14 tooling with as few changes as possible. Seems to me they wouldn't have changed any more than what you've already mentioned.

The thread is the same. The threaded length of the shank is as follows:
P14 = .720" and the P17 = .800"
I hope that answered your qoestion.

Having had the experience of making hundreds of minor changes trying to get the .264 Win Mag to feed reliabily in a M1917 Winchester action, with moderate but not total success, I would certainly never again try to adapt a magazine fed action to a cartridge of significantly different shape. I wouldn't hesitate to rebarreling a M1917 to 25-06 or 6.5-06. I am not very familar with the SMLE, but I can't think why a 303/25 wouldn't be fine in that or a P14, but a .303 rimmed case in a M1917 would be a disaster. I know of a man who tried a 6.5-.284 in a Springfield 03 and it didn't work either. The 6.5-06 has exactly the same case capacity as the .284, and would have fed perfectly.

The P17 chambered in .30-06 uses the same coned breeching as the -03 and -03A3. The P14 does not have the coned breeching but it is chambered similar to any other Mauser variant; with the .303 and it being rimmed it is chambered accordingly.
