Model 70 glass bedding
- Thread starter opto55

My take is that a rifle is not properly built if it is not bedded. Bedding can be done mechanically but it is a lot of work and for specialists. With epoxy bedding compound and especially with pillars it is doable for many. Rewards are long term. The most important part of a rifle for accuracy is the barrel, second the bedding, third stock, last the action.

Did you use lip stick or some sort of indicator to show the action is indeed making full contact with the bedding block?
My experience with my 2, B&C stocks was the over spray of the outer finish onto the bedding block and inside of the inletting was holding the action up, and full contact wasn’t being made….. I also dremelled off the pressure point at the fore end to make the barrel fully free floated on both.

When bedding a M70 with the center screw (Newer ones don’t have it anymore) there’s a little trick you can do. You can even do it after the fact and its actually easier.
The reason for leaving the screw loose is because there is an unsupported gap between the front of the trigger guard and the stock, and tightening the center screw will flex or bend the action to varying degrees. Why not just get rid of the potential problem? I like bedding with Devcon which is is fairly thick. Put a liittle dollop of bedding compound between the trigger guard and stock and fill the gap. That way when you put the screw in you can tighten it against something solid and the potential problem goes away.
Will you gain anything? Well maybe not; but you will at least have eliminated something that could go wrong.
As Murphy pointed out, anything that can go wrong will go wrong.

Lots of great info and advice so far and could definitely help but right out of the gate I wondered:
Did it shoot better before the stock was changed?
Have you shot this rifle, or a different rifle in a similar cartridge more accurately in the past?
How many groups did you shoot to come up with 2”?
If that is a mean average of many groups (+/-), what was the best, and worst (deviation from average)?
And also, how many rounds in the group (3 or 5) and were they all tight with a flier or a random pattern from all?
How many rounds down the pipe, or how old is it?
Factory or handloads?
And how many different loads have you tried of either?
Crown condition, does it have any nicks or scratches?
What scope and mounts, and were they properly installed/tight?
Bedding is usually a good aid to accuracy but lots of other things that seem small can have large impacts on overall accuracy and depending on the answers to the questions above it might not be too far out of what it would have been capable of.
