Re: Bedding a Tikka T3
I have a Tikka T3 300WM. I learned a lot about these stocks, trying to get it to shoot. Granted, my rifle generates a great deal more recoil than yours but some of this may still benefit you.
1st, remember this is a co-polymer stock, which is engineering speak for "nothing sticks to it".
Clean the entire stock with acetone, brake clean, something to remove the gun oil and mold release.
EVERYWHERE you're going to put bedding compound must be roughed up with very coarse sandpaper or a dremel tool.
Make mechanical locks for the bedding compound with the dremel or a small drill.
I HIGHLY recommend you bed some pillars in this stock. It was impossible for me to get repeatable torque until I did this. Also, my screws don't back out and fall out of the stock now.
Prep the area around the action screws as you have the rest of the stock and fill all the voids with Devcon, making sure to get all air bubbles out. Also build up the area around the screw hole in the tang as you will have to drill a clearance hole for the pillar and the plastic is not big enough.
Bed the stock recoil lug like it was in the original (more on this later). I would coat it with release, except the top, and then put a couple drops of super glue on the top, glue it for now to the action, and then insert it as part of the action.
When you've removed the action from the stock after bedding, grind away every vertical surface that will contact the action upon fore/aft movement in the stock, except the recoil lug. You want ONE recoil surface. The stock must not touch ANYWHERE except the 2 pillars, the surface of the bottom and sides of the action and the recoil lug.
Be aware that the foreend of this stock is VERY flexible and Devcon will squish under the chamber of the barrel and flex the forend down.. This will put stress on the barrel. I recommend that you remove this and leave clearance under the chamber area.
After this, it;s just like the other bedding jobs you've seen here on the Hide.
p.s. I ditched the stock recoil lug because it's a POS for a 300WM. If your .223 is leaving no indentations in the aluminum, you're gtg.
OR
You could buy a Manners T4
Good luck
