Mike, no shortage of ways to do this. Assume you are talking your Savage here.
Don't bother with the expensive kits. You can do better for way less money.
The savage already has the pillars in the stock. If putting pillars in a stock, do it first as Ted mentioned above. The bedding takes care of all the support/alignment that might not be perfect with the pillars.
For bedding, I use the Lepages two syringe epoxy steel available just about anywhere. Works great, relatively cheap and enough for up to 3 Savage beddings out of one tube - about $2 to 3 per rifle in goop. Some batches are a royal pain to squeeze out.
Only downside, this stuff will cure in 10 mins. Plenty of time for me as I get everything masked and lined up. All I do is mix, throw into the stock, put the action in and tighten down - takes about 2 mins.
In 1 hour, you can pop it apart and clean up. I still let it cure assembled overnight just to make sure nothing moves. Use the instructions I gave you last time.
With the Savage and most molded stocks, there is little point in trying to bed the hollow forend. Just free float everything with a significant gap around the barrel and leave as it.
Full barrel bedding works only if the stock will never move. Any changes in the stock dimensions or alignment will change barrel harmonics and POA relative to the scope. Big reason this method has fallen out of favor with light sporting barrels.
Works great on heavy barrels or big recoil African rifles as there is little chance of anything moving or distance to target is so close that any change is moot.
