If it were me (and it's not, so build it like you want it...), I'd go with a Bell & Carlson medalist stock (I did just that) as it will save you money and it's lighter than the Rem LS stock. It has a aluminum bedding block in it, so it might shoot good with no bedding (mine is bedded). The cost of the B&C stock is less than HS or McMillan.
If I were to stay with the stock barrel, I'd be inclined to not true the action. Part of truing the action is recutting the barrel threads, normally. I personally would want a new barrel on it if action truing were performed. I suppose it's possible to true the action, and set the existing barrel back a considerable amount to recut the barrel tenon, but at that point, you may as well have a new barrel.
If money is tight, I'd personally be inclined to simply square up the receiver face and screw on a new barrel like a McGowan, Pac-Nor, etc., prefit, as opposed to a full action truing with the factory barrel.
I would only do a Jewel trigger if I were building a bench/target gun. Even the factory Remington trigger can be made quite good if you know what/how to adjust it, though it might be best to go aftermarket. I adjusted my factory trigger. It's pretty good.
I started with a 300 RUM LH LSS I got from my brother in law. This is where I ended up:
27" Krieger bbl. Lt Palma contour. (brake not included in length)
Karl Kampfeld 3 port brake
Action trued
Side bolt release installed
Mini M16 extractor installed
300 RUM chamber (0.098" throat, 0.343" neck)
Wyatt's extended box (3.825" inside box)
Bell & Carlson Medalist stock, with aluminum block and also bedded
Titanium cerakote
Jon Beanland Custom Rifles did all the work. I'm quite pleased with it as it sits. Only have about 35 rounds down the tube, but it's showing sub 1/2 MOA at 200 yards with a Berger 210 VLDH at 3150 fps.
With limited funds, your options are very limited unless you can do the work yourself.
The obvious things:
-Bed the factory stock using some pillars (Brownell's sells some pillars for a low cost. That's where I got mine for the factory laminated stock)
-Adjust the trigger, or go aftermarket (Jewel might not be needed here unless you're doing a target/bench gun)
-Get a Wyatt's extended box, if your factory barrel is long throated (mine was ~0.500" long). This will allow you to get closer to the lands, which should improve accuracy, I would think.
The Before:
The After (with my fat ugly face included):
I am wanting to invest in my LH Remington 300RUM LSS. It is currently bone stock aside from a muzzle break that I had a local gunsmith install. I want to start to improve in the rifles accuracy. I have a small budget $600ish to drop and want to get the most bang for my buck.
I use this primarily for mountain hunting so weight is of concern, but I would like to get it as accurate as possible. Currently considering replacing the laminated stock with a HS precision or McMillian stock and a trigger ( timney, Jewell).
1. Is the McMillian really worth the extra money over HS Precision? It looks like I would spend close to an extra $200 for the McMillian.
2. If I stay with the stock barrel is it worth having the action trued?
3. What am i gaining in spending the extra on a Jewell vs the Timney?
As you can tell I am very green on this but am excited to start learning.
If this was your rifle what would you do with the limited funds to increase accuracy?
Thanks in advance
