First build-model 10 in .308. 30" shillen heavy bull, sss timed/trued, medalist varminter, sss recoil lug.

The barrel wasn't floating, wrapped 3 layers of elec. tape in two spots to center/float it. I have my devcon and searched here and the net about bedding. Definately not hard, but a few questions.
1. how far down do I go on the barrel? 1", 1.5" ??
2. does the recoil lug get bedded on all sides?
3. savages like the tang to float, whats the best way to do it?(layer of tape under?)
4. (maybe a can of worms here)-whats the best way to lock the reciever into the stock? Use the bolts, c clamps, tape, surgical tubing???
How tight does it need to be?

I have another week before my glass gets here, hope to be shooting on Xmas eve.
