building a 500 Jeffery. P14

yeah the barrel was a good find i had it a while before ordering the reamer. trying to figure out what i wanted, i even had the reamer for a year and a half years before i started this project. a 50-110 would be awesome, ive wanted to make a double rifle on a German shotgun for a while now using 50-110 and just sleeve the barrels, i bought 2 rem 700 SS 50ML barrels and a merkel SxS shotgun but loved the gun so much its still a 12g.

im not sure if it would fit but i believe so with a little work. its only 88mm long, a 3006 or 300win mag is 85mm long


i got some more work on the rifle done. but my stuff ships to BC tomorrow so i have to pack it and send it ill get to finish it when im there.

i still have to bed the action and install sights, also test fire it remotely.

i had to sand down the front of the stock as the barrel is wider then the stock itself at the muzzle. i also profiled the recoil lugs a bit nicer looking.

there is 3 videos that show loading and cycling the rifle.
it holds 3 in the mag but i cant close the bolt on 3, so its 2 in the mag and 1 in the chamber.

it weights 10 pounds and 1/2oz with 3 rounds

first video you can see i still fumble it while loading it but by the 3rd its getting better, still a pain in the ass to load but at least it feeds well

i got the videos on youtube now so they should be a lot easier to watch
2nd video shows bolt not closing on the 3rd round in the mag, if i extended the mag about a 1/16" it would hold 3+1. i may do that later on.

Its coming along. Ill have pics this weekend i plan to assemble it and bed the action saturday. And yeah the action is huge
I wish i used one for my 460 weatherby build. It would have been easy to fit that case in. As of now i have to use round nose bullets with a max OAL of 92mm opposed to the 94mm factory rounds are.

The P14/M17 actions are great for big bores. I've done up to a 475 Ackley Mag on them, as well as a 450 Ackley and a couple of Wby's back in the day. Good actions. - dan

yeah my next build ill use a p14/m17 action for it as well, this was very easy to work with and not much expense if I scrap the receiver opening up the feed rails or something.

ill replace my 460 Weatherby barrel with a none prohib caliber. probably ill go 416 Weatherby just since it all fits with only a barrel change

then ill need a big .458 to replace the weatherby so ill do that on a P14/M17 action.
for how cheap and big they are, its hard to go wrong.
 
I havent seen the receiver on the EE i looked though after reading your post conor_90

And zywina i didnt get to fire it yet. Those videos were take the last day i had it. I shipped it to BC with all my other stuff. So it will be sitting there waiting for me when i get there on may 1st. Ill let you all know how it shoots.

But it feeds from the mag awesome. Ill bet ive loaded it and cycled it 100 times without a single issue. Loading the mag causes the most issue it always cycles fine
 
So do I. Maybe bolts in both '06 and .303 as well. One of these days I'm going to sort out all the P'14, M1917 odds and ends, and see exactly what I have. I know one receiver has had the ears neatly removed.
 
i hope to fire this thing here soon. the folks should be gone/closed up for the summer soon. i have the cross bolts finished and the recoil lugs bedded. test fire is the next thing I need to do with it. i think ill oil the first three rounds and remote fire them with a string as to "proof' the rifle. i don't think it needs it at all but i wanted to test it remotely the first time anyway and I always to test the stocks ability to absorb the recoil so at the same time i might as well oil the casing.

seems like a good receiver for a project
 
For your proofing, I would suggest having the butt up against something that is resilient. Something to absorb some of the recoil - sandbags, whatever. I like sandbags behind, below, on top.
 
I did plan to put the butt against something hard before fireing it as the proofing is more for the stock splitting then anything else. I dont want to use something to hard but enough that its harder to move then my shoulder. Sand bags would be a solid idea. Thanks
 
I recall a gunsmithing article in which a damaged stock for a heavy recoiling rifle was repaired, rods inserted, etc. The stock was tested by being fired butted up against a tree. It survived, the 'smith was pleased, but I thought it was overkill.
I like sandbags because they offer resistance, but have some give. Bags below and on top keep the gun in place without it being tied down. Should a barrel or action fail, the bags will contain fragments.
 
I suggest standing when testing using a ladder or tripod for support.
It is a lot more comfortable to absorb the recoil.
I recall practicing with my 458 Ackley in a lighter gun in -35 weather and that was the only way that felt at least doable.
(unless this is a test of structural integrity ...than use a tire as discussed above)
