I inherited from great grandfather a sporterized P-17 BSA brand. I have since put a pile of cash into this unit, speed lock, #### on opening, muzzle brake, MPI glass stock, modded magazine box, Tinmey Trigger, re-chambered to 300 win mag, and a custom one piece picattiny rail. The last piece of the puzzle was to be a fluted 27" custom barrel. When the pic rail went on the gunsmith noted the barrel had a slight left cant indicating either the threads in the action or in the barrel were not cut straight. The rifle shoots ok but I would like to finish this project, too much money and its gone too far with the work to quit, not to mention it has sentimental value. Has anyone heard of this before and is it fixable?
 
Seriously , more than looks, want 27" barrel, flutes are for looks, the chamber was cut too large by the last smith, its hard to resize brass small enough as the chamber is on the large side of dimensions and I am looking for more accuracy. Yes thats hard to quantify by adding a new barrel to an older action. Its the sum of the parts, looking for reliable 1 inch hunting rifle. Shoots OK hmmm it groups 1.5 - 1.75 inch groups.
 
You could have bought a factory rifle for less money than you have spent that would shoot less than an inch with factory ammo. Installing a new barrel if properly done will correct the rest of your problems. It will probably cost even more than you have spent.

Maybe try a Lee collet die first and see how that works for accuracy.

Gee thanks, did you even take the time to read the post, its not about money, its about a project that has sentimental value and is 75% completed.

...I read the post... you asked, "was it fixable?" and stated it gets 1.5 to 1.75 inch groups with an over size chamber.

and I stated, "Installing a new barrel if properly done will correct the rest of your problems."

You also stated, "I have since put a pile of cash into this unit, speed lock, #### on opening, muzzle brake, MPI glass stock, modded magazine box, Tinmey Trigger, re-chambered to 300 win mag, and a custom one piece picattiny rail."...

I said the new barrel will probably cost even more than you have spent.

I thought the sentimental value was long gone as the rifle with a new barrel installed will bear no resemblance to the original what ever. It sounds like only part of the action is still original as your great grandfather owned.

Installing a new barrel if properly done will correct the rest of your problems. You can salvage the muzzle brake and have it installed on the new barrel.

Assume you have rechambered the ORIGINAL 30-06 barrel to 300WM and changed the bolt accordingly? Or maybe it was already sporterised to a 300WM when the rifle was purchased way back when?

You plan to add a fluted match barrel as your final step in the build?

If the above two points are correct, then why worry about the state of the original barrel? If you are willing to make the investment for a fluted match barrel and have it installed, I can assure you the accuracy issues will dissappear with proper handloads. BUT you better really like that P17 action.

I have built several of these in days past when inexpensive donors were every where. Today with the cost of match barrels and installs, you better really like this action.

PS, if the chamber is large, why are you trying to make the brass small? It just needs to be sized enough to fit.. neck sizing fireformed cases will go a long ways to help with accuracy. So will be match bullets set up to fit the throat of the chamber.

Am I getting this correctly, you are worried about the original barrel that was re-chambered too big and might be misaligned when you want to put another barrel on the rifle?

GST, yes you are correct, the sentimental issue is mine, I was looking for advice on how to fix the issue best not a lecture on the cost, I do have multiple quotes on a new barrel, just trying to make sure the money is headed in the right direction, the project is too far to quit. The action was originally in 30-06, has a 24 inch barrel, was opened up to 300 Win on the suggestion of a smith' also had the firing pin hole straightened by another competent gunsmith so heres where we are.

Jerry, we have talked once, I did try to engage you to finish this rifle and you politely declined. I do neck size but after 3-4 firings neck sizing is not enough and the bolt is hard to close, its long throated compared to factory and the magazine box can take advantage of this. Thanks to all for your input.

Not to be a ####, but how much sentimental value can a rifle that you have replaced 90% of the parts on, have remaining? To quote Kenobi "He's more machine than man now".
 
You are a ####, provide some assistance to the post or piss off, if you want to start #### go gossip with your girls , what a soap opera.
