From the Minutes of the Midland, Tx, BOD meeting:
In order to help clarify the definition of the sandbag, without an actual equipment rule change, Bukys moved to reword the sandbag definition (page 4 of Official Rule Book and By-Laws, Revised Edition No. 35 under B. Definitions, 14. Rests) to read:
(c) Sandbag.
(1) The Front Sandbag shall be a bag, without additions, containing sand only, and at least ½ inch thick over its entire surface. The bag must be able to be deflected horizontally at least ¼ inch with finger pressure at any point. The portion, which contacts the rifle, shall contact the entire surface under the fore-end.
(2) The Rear Sandbag shall be a bag, or combination of bags containing sand only. The bag must be able to be deflected horizontally at least ¼ inch with finger pressure at any point, except for the bottom 1 inch of the bag, which may be hard. A vertical spacer under the rear bag will be allowed as long as it incorporates no adjustments for windage or elevation. The vertical spacer shall not contain any protrusions, which can be inserted into the bench top or the sandbag. The rear bag shall not be contained in any manner. No metallic materials may be used in the construction of the sandbag. Tape
on sandbag is legal. Griffin seconded and the motion was unanimous. (Dunrud rear ring spacer was also approved to be included in this section. See page 9 of these minutes for final draft.)
The Edgewood front and rear sandbags were presented to the Board of Directors by Dodd and were approved by the Board as being legal sandbags. The Board also requested for the minutes to show that the Lester Bruno sandbags were approved at the September 16, 2000 Board of Directors Meeting held in Warrenton, Missouri."
The rulebook on the NBRSA website has apparently not been updated. (I knew I was at the meeting where the members voted to allow the Dunrud spacer, but forgot which meeting it was). To me, James Mock, this still says that you cannot glue anything on the bottom of the bag (i.e., they never changed the part that says the bag has to be a bag or collection of bags -- which is not what a spacer is -- and they retained the part that says that the spacer may be under the bag, but that language doesn't go so far as to say the spacer can be attached to the bag), but that the bag itself can be constructed in such a way so as to not meet the deflection requirements set forth in the rule (like the Edgewood and double layer Protektor, et. al. bags). Other than that, the Board, and ultimately the membership has ruled on the legality of equipment on a case by case basis. Durud legal. Edgewood legal. Bruno legal. Sorry, but there hasn't been the sweeping rule change you stated in your post, but granted the likelihood of having a set up declared illegal by the BOD or members is pretty remote.
Heres another exerpt from that meeting:
"Creach asked for volunteers to serve on the Rules and Equipment Committee. This committee is to look for conflicting statements in the current NBRSA Rulebook and then to make recommendations for changes to the Board at the 2003 Annual board of Directors Meeting. The following 8 members volunteered to serve in this capacity: Butch Fjoser, Don Geraci, Mike Marcelli, Bob Metric, Don Nielson, Jackie Schmidt, Jerry Stiller, and Dennis Wagner. At the conclusion of this General Membership Meeting, the Directors will select 5 of these volunteers to serve on this committee. The
Board Meeting reconvened at the Midland Shooters Range (Midland, Texas) on Friday, July 26, 2002, at 3:05 PM in the Stat House and the Directors chose Dennis Wagner (Chairman), Don Nielson, Don Geraci, Bob Metric, and Jackie Schmidt to serve on the Rules and Equipment Committee."
Oh yes, I remember it well. Toodles.
