I am going to be dropping my new Sendero in .300 Remington Ultra Mag off at the gun smith to have him take off the decelerator pad and put on a Limbsaver. I was wondering while doing this if having the gunsmith glass bed the action would result in any noticible gains? I know the gun is already aluminum bedded, and was wondering if it's even worth having glass bedded.

Also, will the .300 "shoot out" the beddign after 100 rounds or will it actually last.

Don't know but I admit I have pondered the same thing with my Sendero. With that thought I would add that the gun is so accurate the way it is I doubt that my shooting skills would reflect any gains at all. I have used Accruglas, Marinetex and Devcon for bedding on several rifles and I believe that anyone of them is capable of holding up to the pounding of a .300 RUM indefinitely if properly done.

Anymore, I glass everything. Got one in glass as we speak. The aluminum bedding block is great at keeping the action level, and it prevents the action from distorting when you tighten the guard screws. The recoil lug bearing against the aluminum block helps keeps the action from moving laterally, but without something to keep the action from shifting sideways under recoil, then screws quickly loosen and become damaged. We all know what loose screws do for accuracy and surrounding material...

I dropped it off just a few minutes ago. The rifle will be back in my hands in a couple of weeks. Just out of curiosity why would they not be able to install a Limbsaver pad on an HS precision stock? They mentioned that they could not do it because HS Precision had "burned" the stock towards the rear and that it would not be possible, they then offered to install a KDF muzzle break to tame the recoil. I obviously declined, but what's up with this?

I don't know what "burned" is applied to a synthetic stock. do know that some of the synthetics have a smei-hollow core in the butt and require a "filler" to have something to bond to. I would ask him what "burned" meant. In my experience, good epoxy will stick to any roughened surface.

I'm looking at the cut off end of an HS stock as I type this. The original pad is glued on so your gunsmith will have to cut this off. Perhaps he's afraid he'll chip the paint.

The butt stock has a tight cell foam core. What I will do with these, is drill the foam and glue, 2 ea. 1" x 1" hardwood dowels for which to attach the new pad. After the pad is fit, I will apply epoxy and screw it down.

My Sendero is glassed but I can't tell you the difference because I glassed it before I shot it. My smith took 3/8" off the stock and added a Decelarator and everything works perfect.
Good luck with your project.

I had a Sendero in .300 Wby in the shop last year that was trying to group but would throw one and sometimes two rounds about 1 1/2 inches out of the group.

I glass bedded it and tuned the trigger. It shot several 5 shot groups at 9/16 inch to 3/4 inch. All very round groups and no fliers.

Years ago this did not makes sense to me as any machinist will tell you that very accurate mating of parts can be obtained by placing a round cylinder (Rem action) into a V block (Sendero bedding block). I thought about it a lot, did some research and came up with this. Remington 700 receivers are machined first then heat treated. Any machinist can tell you what happened to that 4140 receiver when it was quenched during heat treatment, Warpage. So the V blocks are reasonbly true but some of the 700 receivers are ever so slightly warped. Hence they do not fit the V block as well as we would like. When Remington manufactures their 40-XB actions they are heat treated then ground true so they will be an accurately shaped cylinder and reasonably concentric to the bolt bore. If you look at a 40-XB action you will notice the serial number and markings are etched rather than stamped due to heat treating and grinding first.

Thanks for the help guys. I think once I get this rifle back from the smith I will certainly attempt the recoil pad installation on my own. What gets me is that this is a shop of 6 smiths that are supposedly competent in what they do. It's probably the biggest shop (non-chain) in Austin, TX www.mcbridesguns.com and after receiving feed back on this forum and others I still can't figure out why he said what he did. Just for my information, does anyone have a list of a good smith here in the Austin/Round Rock area?
