I have a new Howa 1500 varmint and looking for information on glass bedding the stock. It looks like the best thing to do is pillar bed and glass bed but this is where I'm confused. Why is this best to do both than one over the other?
Good question !!!!
When you bed only, the stock material can compress over time and change the POI and the torque
on the action screws.
The pillars make the fit a floor metal to pillar metal to receiver metal fit (Nothing can compress
with time).
If you try to pillar only the action will/may not contact the stock and be allowed to shift around.
The idea of a full pillar bed is first to make the stock fit the action perfectly and stress free so there
is no flexing/binding of the action and no compression of the stock or the bedding in the areas of
the action screws.
When pillar bedding is done properly the rifle is very consistent and will last a long time with minimal
removal from the stock.
In most cases the bedding will out last the barrel if done right.
To me one is not good without the other. Install pillars and bed the action and you are done. A good
bedding job with pillars will also tell you when a load is changing(Different batches of powder, primers
or cases) So you can fix the problem instead of chasing non existing issues.
I completely bed ALL stocks including inserted/V Block composite and laminates.
This Is just my opinion.
