This subject is difficult to write, I'll try again because on the vital importance of the Front end draw pressure and accuracy..

As a starter, too much draw pressuer is better than too little.. Too little and nothing has been accomplished. Too much and a bit more wear on the barrel results if you shoot rapids..

Front end draw pressuer is the downward pull of the stock bearing against the stock ferule lip.. I can not provide a poundage number, but it is considerable. Enough to require four finger and thumb pressuer from my hand to break contact between the two surfaces.

Front end draw presssure is built into a rifle during the bedding procedure, there a number of methods to do this, all good and proven..

To imporve draw on a non bedded rifle or one that did not have enough after being bedded is not difficult. Do a search on my past Posts, one of our Members did a excellent photo display of exacty how to do the job.. There is nothing I can do to improve his effort.. Spend a few mins and find it, maybe someone will assist you because I'm late for my Tee time,, and the guy I play today is from Pecos, and they haven't heard of waiting five mins.... Art

When I was working on NM M14 military rifles we were instructed to set up the draw pressure at 4 pounds. Some of my builds were as much as 7 pounds and I think Art is right about having more is better then less, but more than 7 pounds may be excessive. One of my best personal rifles took two hands to squeeze the stock to the barrel. It would shoot 3/8" groups... This was a McMillan stocked, Krieger heavy barreled, rear lug receiver set up.

Ted,

Was any method in your Guard experience tried to determine a method to measure draw, or how to bed in consistant draw.

One of the better M1A's grouped very well slow fire, in the rapids it was a mess.. This rifle had a light touch contact to the lip. Found the same results in attmepts at free floating.. A number of free floaters were always at the Matches, they were never a threat in the rapid fire stages, the owners insisted,,,,, rather than admit a mistake, that free float was a failure... People are like that, not us of coourse...Art
