Bedding scope base

[turbowhunter]

I have a Rem 700 that I'm mounting a one piece scope base on and it's pretty obvious that the receiver is off. When I tighten all the screws on the base I can see the base twist. When I just put in front screws in and tighten there's a gap in the rear and its tilted to one side. When I put just rear screws in and tighten, there's a gap to one side in the front. My question is how do I know if the front or the back is true? Do I bed the front or back? What's the best material to use as bedding compound and release agent? I've tried different bases and they do the same thing so I'm confident the receiver is off. Thanks

I used JB Weld and neutral shoe polish on the last one I bedded and it worked well.

I'm no help on the second question about which end to bed. I ended up bedding the end that didn't come in contact with the receiver when the opposite end is tight.

Before you do anything try another base. Sometimes the base is off and the rifle is fine.

Oops missed it.

I would do what 6.8 is suggesting since that is the case.

I use Devcon 10110 but I'm sure JB Weld would work also. I would bed both front and back but just tighten down one end or the other first. It won't be far enough off of alignment to lose any sleep over wether you go off of front or rear screws. A light coat of shoe polish or Imperial case was works for release. I used the case wax on two bedding jobs and it worked okay.

I would start with a good one piece base. I personally use ken farrel bases and rings. Really high quality and precise. I use jb weld to bed, kiwi neutral for release. Ken's bases have channels for the bedding compound. But if your rifle is that jacked up, why not take measurements and verify, or have a competent smith do it for you? If it is, have it fixed. Just doesn't seem worth it to fight the problem instead of fix it. I like to do things once and do them right so problems don't rear their head on down the road. I'd hate to have a trophy in the cross hairs when Murphy shows up.

I tried the base on an older 700 receiver and it sat flat. What do I need to measure? How else could this be fixed by a gunsmith?

I guess we need to figure out what we are going for here. Is this a long range rig, or more of a regular hunting rifle that will primarily be using Kentucky windage for fairly close shots?

When you mount your scopes do everything it's perfectly level. Then afterwards test it, tall target, scope tracking/repeatability tests? Just trying to get a feel for what level of precision we are looking for.

You would be measuring your receiver to make sure it's true, or close enough to it. You could always have it machined if needed. Not that you need to do any of this if you are just looking at shooting some deer at typical Texas deer killing ranges.

It's a long range varmint rig

I guess just find you a good step by step tutorial online. I use kiwi neutral shoe polish as release agent. I use jb weld for my bedding but there are plenty of other products available. After you get all of your screws, holes, receiver coated with release agent then you apply your bedding. The idea is to get it somewhat snug where it barely makes contact. Then after it cures you torque it down later after cleaning everything up. Here is the instructions I use. https://www.kenfarrell.com/index.php...ormation_id=11

Just have your q tips, plenty of paper towels and acetone ready to go in case you over do it on bedding.

Ive never done one that's as bad as your receiver is, but I guess bed the base, get everything mounted correctly, test it really good, then if you aren't happy with the results decide the next step. Cause it would be expensive to machine the receiver.

Thanks for your help

Varmints? Just keep shooting.

Not like you're going to waste the tag of a lifetime if you miss.

It would not supprise me to see the screw holes drilled off. It's happened before and that sounds to me what you are dealing with with a twisting like that. What is the brand of mount?

My suggestion is drop by your local smith and have him look at it and get his suggestion, or call big green, they have been known to but people new receivers or while new rifles

The mount is a warne tactical. I put it on a different 700 receiver and it sat perfectly flat. Then I took a different warne tactical rail and put it on the varmint rig and it was off exactly like the first one. When I put pressure on either front or back, it sits flat where I put pressure. When I push down on front and back at the same time, it shifts to the side like it is unable to sit flat on front and back at the same time.
