I recall reading an article many years ago about the negative effect a "loose" fitting shroud has on the accuracy of Remington actions (and clones)
The idea was that the relationship bettween the lower two faces of the shroud and the contact points on the action guide rail was improved if there was some kind of bushing "stud" fixed to the two points of the shroud base.
Ive been trying to locate the article (it was online) and im damned if I can find it - ive tried the precision accuracy forums stateside, to no avail.
Can anyone recal the article or point in the right direction.
Basically I have the plan of fitting two delrin (or similar slippery hard material) studs to the lower contact point on the shroud - machine them down to they are a smooth interferance fit on the guide rail of the action to stop the shroud and bolt twisting on cocking / firing cycle - so alignment is maintained.
I may be trying to fix a probnlem that doesnt exist, but the bolt and firing pin cannot be concentric to the centreline of the bore if its a loose fit, having detrimental affect on accuracy.
Anyone thoughts or have an opinion on doing this?
