Gentlemen,

I have a chance to pick up a P14 action for a very good deal and am thinking of building a 505 Gibbs from it. Its going to be used more for play than hunt at first.

My idea would be open sights synthetic stock weighed down a bit with a load of 500gr monolithic at a gentle 2300 fps with no pressure.
This is my idea and could be a long project over 3 years but would like to know if anybody has build some .50 cal rifles with the P14 and your experience with it. Or have any other ideas of other .50 cals to build on it.

Thanks

Not a 50cal......But, how about
my 585HE in it, any gun the 505 Gibbs
fits in the 585HE fits. You can shoot a
light load 750gr at 2300. Ed

Try Geoff McDonald from Woodleigh Bullets.

He built 4 or so of the 505 / 530 Woodleigh's
on them plus he knows what he is talking about.

The concept came as a PH in SA wanted an Ultimate stopper type gun and Geoff had already done the 530 on the 460 Weatherby Case.

.

How about a .500 A-Square? It is based on .460 Wby. brass.

the 505 or the 500 jeffe are great fits . the 500 jeffery is easier to fit..

and the 500 accrel is easier still to fit into such an action

here's Jim's article on how to do the metal work

Fredrik, you'd need to gain some considerable weight in order to handle the recoil of a 505 Gibbs. Oh....I just checked your Avatar...I guess you've got that covered!

I love the P14 action. I strongly suggest a single stack magazine w/coffin floor plate. It fixes almost all feeding issues.

Go big or go home, right Fred?

OK I really don't see the issue with the recoil so much as a 458 lott with 500gr is just a bit slower so it will kick a bit more than a 458 lott. Or am I wrong here considering you use a properly weighted rifle that fits ?

What I like about the case is the low pressure of the big case which will avoid the sticky situation in hot weather. And I plan to use it with a 500gr Mono instead the normal 525gr.

The 505 Gibbs, kicks a fair bit more than a 458 Lott. It holds anywhere from 130gn to 145gn of powder (depending on the burn rate), a lot more than the Lott's 85gn or so, and it has a bigger bore, so you will end up with a significant increase in felt recoil for rifles of equal weight

I've actually built a few .505 Gibbs rifles from P14 actions with 1917 enfield bolts MYSELF and its a fair amount of work. There is quite alot of machine work involved. I think you will find that its gonna be real expensive. Personally if I wanted a .505 Gibbs, I'd buy a CZ 550 based one and have someone smooth it out for you. You will have a much greater chance of winding up with something that actually works rather than the project becoming another AR horror story.
As for recoil. Yup a .505 Gibbs is in another league than a .458 Lott. Its not at all unmanageable, but way more than what most guys are used to. FWIW the .505 Gibbs is the least shot gun in my big bore battery. Not really sure why, just doesn't get me as excited as a .600OK.
BTW, if you can shoot a Gibbs well, you can shoot a .600OK just as well and the .600OK is way more gun. You can build a .600OK on a P14 just as easily or not so easily as you can a .505 Gibbs.-Rob

Thanks Rob for more input.

The P14 action will have the bolt face for the .303 and not the 30-06 so it will be a step easier but still some work.

Go for the CZ that is what i am doing.Who is going to build the gun for you.

Cabelas has two CZ550 in 505 Gibbs for sale now. Cheaper than you are ever gong to build one!
505 Gibbs

I've never fired a 505, but have seen people who have. . .It has PLENTY of recoil! Somewhere I have a picture of Rich shooting his and the rifle is hanging in mid air!

I am not sure who will be building the gun yet I was thinking of getting the basic parts first then giving them to a gunsmith instead of giving him piece by piece.

That deal on Cabelas sure does look very sweet if only I could buy it an bring it over.

There is no comparison in recoil between a 458 Lott and any fast 50! I can shoot a Lott, I will NEVER again touch of a 50 caliber OMG!

If you like i can help.Barrel from Truvelo R5500-R6500. Synthetic stock from Armtec the Jeffry stock 2hand R2000.CZ action from MJ Wapens in Naaboomspruit Limpopo.

nongwe,

Speak to me that sounds like a plan.

Steph, I fired a couple of shots with a 450 Rigby and that is pushing it a bit as well should be close to the same recoil shouldn't it ?

Depends on how you build your rifle and if it fits you or not.I have two friends that both use the 460WB the one kicks the S out of me the other one doesn't kick to hard.At the end of the day it all depends on how a rifle is poet together and if it fits the user.Sal no vir jou PM vir kolf,loop en Jan van MJ Wapens.

I don't know as I have never shot a 450 Rigby. I shoot regularly my 458 Lott loaded to 2420 fps with 450gr A-Frames and to me the recoil is quite stout. I have shot a 500 A Square shooting 600gr at 2350fps, and that makes my Lott seem like a 30-06 in comparison. The 500 A Square was a couple pounds heavier than my Lott and had a super soft and thick recoil pad to boot, which I do not have on my 458 Lott. The fit of the rifles, to me anyway, was basically the same.

Here is me firing my 505 Gibbs over the chronograph

That was a 600gn load at 2250fps or there abouts. The rifle is a custom rifle based on a Granite Mountain Arms action. It weighs in at 11 lb without the scope. The scope is only light anyway, a 2.5 Leupold compact.
