I know alot of folks bed their rail type scope bases, to get a solid non flexing platform. My question is, is it beneficial to bed the bases of Hybrid type rings such as Talley Lightweights or Hawkins Precision Hybrid rings?

It will definitely be more difficult to bed a two piece setup. I have a thought in my mind on how you could do it, but I'm not sure it would be any more beneficial than a good lap job.

I am talking about bedding the bases to the action, not the scope to the rings.

Yes. I know what you meant. Bedding a one piece accomplishes two things. First is a stress free mount for your scope. Second is permanent/semi-permanent attachment of the base to the action creating more surface area contacting the receiver. For a two piece base, you're going to have to design a way to make the two base pieces a single unit to ensure uniform bedding between the front and rear to create a stress free scope alignment.

I'm not sure the juice is worth the squeeze in attempting to bed a two piece set. Torque them on with blue Loctite and lap them.

I’ve actually got an idea of how to do it correctly, just have to give it a go.

Who all besides Talley and Hawkins, makes 2 piece hybrid Base/Ring combo?

It can be done. Let us know how it turns out.

Talley and Hawkins are the only ones I know of.

I guess you could mount the scope in the rings then see how it fit onto the action, sort of reverse engineering it.

My smith put some red Loctite on the bottom of each base and torqued to spec. He cleaned the excess and said let dry.

How do you bed a 1pc base without getting compound in the screw holes?

And IS it really worth the trouble?

Thinking about doing it

Google jeff brozovich bedding video for a how too. I bedded my last one. For what ever it is worth I think it is worth doing.

This is a really good question, and I think there are benifets to bedding Talley Lightweights instead of lapping them. (Talley advises against lapping)

In practice it is a bit tricky to maintain alignment, but totally worthwhile if your receiver is out of spec.

It's easy to see if this is the case - torque the front base down, but just start the rear receiver screws. Mount the scope and torque the rings. Look at the interface between the rear mount and the receiver. If you can see daylight, bedding might be worth considering.

I am an advocate of positive alignment, and I view lapping rings as a last resort.

A good alternative to talley lightweights is the NEAR alpha hunter. One piece steel direct mount that weighs about one oz more than the talleys (my 30mm alpha hunter for model 700 long action is 3.4oz)
