Being left handed the only company I know of who makes a synthetic stock for a short action W70 or a Ruger medium action is McMillan. I have two each of these rifles on order and plan to add a stock to both. I am capable of doing minor inletting and have glassed many rifles over the years so I can handle minor stock work.
But are there Custom fit drop in's truly a drop in replacement stock?

Absolutely.

I use them all the time.

I usually bed them in marine-Tex.

Only way to go.

If the rifle shoots well is there any reason to rebed ?

Check over on www.24hourcampfire.com in the "Custom Rifle" Forum, Rick Bin is a dealer for McMillan stocks and gives a discount under the factory price.

Every mcmillan I've odered has been an excellent fit without any tweaking. However, I too usually bed them anyway, well, at least the heavier calibers...

If the rifle shoots, bedding is not necessary.

Fjold,
Thanks for the tip. I sent Rick a PM.

My McMillan to replace a Sako synthetic stock was a perfect drop in. That gun is my most accurate and never needed to be bedded. I just sent them my magazine box and floor plate, did not have to send the whole gun.

Worth every penny and a few more.

I suspect if you plan to leave the barreled action in the stock, and it shoots well, there's no real need to bed it. After all, that's how some factory stocks are shipped.

OTOH, if you plan to take the barreled action out of the stock (travelling broken down, for example) and expect it to shoot near the same point of aim when you replace it, a little bedding material would be well advised.

Yes, but.

I am also left handed and have two McMillan Sako Classic stocks and one Sako Varmint stock on my Sakos. I pillar bedded all three. They all shot well with the factory wood stocks, better after floating the barrels and bedding the lugs. But I wanted McMillan stocks and once you spend the cash for them, why not go ahead and bed the actions? Kind of like belt and suspenders I know, but I also know that the rifles shoot sub 1/2 moa every season, without fail.
