There are many tutorials on Youtube for stock bedding, if you have not done this before, refer to a few of them first.

All precautions and caveats that apply to normal bedding compound apply at this stage, such as the application of release agent to the metal and areas of the stock where you do not want the epoxy to stick to.

Mix black tint into the Epidermix, and bed the barrel along it's entire length in the stock.

Afer applying epoxy to bed the fore-end, do not permit the weight of the barrel to rest on it : make sure there is no load whatsoever on the fore-end while the epoxy is wet. Support the rifle barrel without the fore-end taking the weight of the barrel, while the Epidermix dries. The fore-end is still slightly flexible, and the weight of the barrel if the rifle is supported under the fore-end will cause additional epoxy to be expelled from the sides, leaving a thin gap when dry and the rifle is picked up. Taking care of this will prevent any vertical movement when the fore-end is relieved of the barrel weight.

If you support the front of the rifle by the barrel when the Epidermix is wet, it will ensure that the barrel channel is a perfect fit to the barrel, and when dry, there will be no vertical movement at all.

In six hours the epidermix is hard, and you can seperate the stock from the barrelled action.
