A loose fore stock will cause the Enfield Rifle to string is shots vertically, a loose butt stock will cause horizontal shot stringing.
I would strongly suggest to anyone who is having a problem with stringing their shots vertically with the Enfield rifle to temporarily to remove the front trigger guard bushing and retest the rifle for grouping.
If your grouping improve you have wood shrinkage and your bushing is too long and should be shortened. Placing cork under the the barrel at the fore end tip will not fix the problem and it will only cause damage to the forward draws area of the fore stock.
Please note you have been warned before NOT to remove a snug fitting fore stock by wiggling the fore end tip up and down because it will damage the forward draws area and make the fore stock a looser fit due to wood crush.
Also the standard practice of placing shims under the hand guards will keep them from from shifting fore and aft during firing.
The reason I supplied 95% of the Enfield manuals you see on the Internet today was in the hopes of starting an Enfield Renaissance by increasing everyones knowledge. If we are to leave the "Dark Ages" and start a second Enfield Renaissance it would help to read these manuals.
Up pressure at the fore end tip controls grouping and vertical stringing and cork at the front of the stock will not fix a problem at the rear of the stock.
