Read the bedding section of the Canadian No.4 manual link below pertaining to the draws area, the "draws area" acts like the second "missing" action screw. The front part of area (A) of the fore stock pushes the stock to the rear and into contact with the reciever ring. You need to see where these two areas of the stock are touching their corresponding points on the receiver and some times the rear of the stock must be "tapped" into position. Both the front and rear of the draws area (A) should be touching equally on both sides and this also "centers" the barrel in the fore stocks barrel channel. Meaning adjustments should be snug in area (A) and also center the barrel in the fore stock.
Study the bedding diagram until you understand what the draws does and you understand it effects on up pressure. An Australian once told me using Aussie humor that the rear of the fore stock should be as tight as buggery.
Warning the up and down position of the rear of the fore stock also controls your 3 to 7 pounds of up pressure at the fore end tip. Also remember the forward trigger guard screw is the fulcrum point of the fore stock or the balancing point like a kids teeter totter. Meaning moving the rear of the stock down increases the up pressure at the fore end tip and moving it up decreases the up pressure.

Below at the bottom of the photo, the rear of the stock where it contacts the receiver ring does not have to be touching 100% "BUT" the contact must be equal on both sides. The front of area (A) top of photo is where normally the forestock is shimmed to force the stock into contact with the receiver ring and up and down adjustments.
Pay close attention to the "steel doweled stockbolt keeper", this was how the Enfield was originally adjusted at the rear draws area. The rear of the "steel doweled stockbolt keeper" would fit against the receiver ring and the tips of the "steel dowel pins" would be filed and fitted for proper adjustment. This made the rear of the stock a tight snug fit when contacting the reciever and prevented upward movement of the rear of the stock. This part was deleted to speed up the production of the rifle but required the armoures to spend mor time fitting and readjust the draws area. Meaning you will spend more time shimming and adjusting the draws area for proper fit when the wood dries out and shrinks id not kept oiled with raw linseed oil.
Below the front trigger guard screw is the fulcrum point of the forestock.
NOTE, I used engine oil instead of lamp black and rubbed the barrel and receiver with this oil and installed the forestock and then removed it and checked to see where the oil contacted the wood.
