Ok we have an old worn out rifle we want to rebarrel how far do we need to go. Will putting a new barrel on alone improve it much over a factory rifle. Should we have some work done on the action. Do we need a new stock or will bedding the old stock help enough. With that said I am assuming the old stock fits you really good and you enjoy it. So as asked assuming we want a real shooter just how far do we need to go.
Budget was not mentioned...So, I going to assume you're like many of us....Not RICH & not POOR, kinda in the middle. Having said that I'm not the type that believes half measure.
I'm also going to assume it's an action worthy of spending some $$$ on.
Yes, a new barrel would be a big improvement. I would say,
1st a highly skilled smith.
2nd a high quality bbl.
3rd True the action & square the bolt face, polish raceways and lugs.
4. tune the trigger, replace "if" necessary.
On the stock, here's where you "might" save some money...
If it's still in nice shape and still feels good and solid and fits the shooter correctly.
I'd pillar and glass bed it... For a hunting rifle this is usually adequate.
This will allow you to judge if you want to go the extra mile for a new stock.
Example, Here's couple of my shoot'n Irons. Both with the treatment I mentioned.
1. Rem 700 Mountain, 22" Lilja bbl, .223AI w/ Basix Trigger @ 1.8lbs topped w/ 5x20x44 SF
2. HOWA 1500, 25-284, 24"Lilja, Lee SIX Stock, factory trigger @ 2.10 lbs w/Ziess 4.5x14x44 SF
Both rifles have Warne Rings & Bases
