NBRSA Changes Sporter Rules — Bukys Builds to New Standards

The National Benchrest Shooters Association (NBRSA) has adopted new rules, loosening restrictions on the Sporter Class of benchrest rifles. Now a Sporter fore-arm may be any width (or angle), and the underside of the buttstock can have any angle. Previously, fore-arm width was limited to three inches, and the bottom of the buttstock had to be angled up. (NBRSA Rules will continue to require this “up-angle” geometry for all Light Varmint (LV) and Heavy Varmint (HV) rifles). In addition, the NBRSA opened the Sporter Class to any caliber “no larger than .308 Winchester”.

The idea behind these changes is to allow greater innovation in at least one class of benchrest bag guns, and to avoid “redundancy”. Currently a 10.5-lb Light Varmint can be shot as a Sporter, so long as the LV complies with caliber rules. For practical purposes, that meant Sporter Class was redundant with the Light Varmint Class, and there was no real reason for the Sporter Class to exist anymore.

The Sporter weight limit remains unchanged at 10.5 pounds (including optics). All current LV and Sporter rifles will remain 100% legal under the new rule, so no one is forced to go out and build a new rifle to shoot in Sporter class. But if you want to try a more radical stock design, now you have the opportunity to do so. Here is the text of the new rule:

NBRSA Rule Book (New Sporter Rule)
B. Definitions: 2. Equipment (d) Sporter Rifle

A Sporter Rifle is defined as any rifle having a safe manually and mechanically operated firing Mechanism and must not weigh more than 10.5 lbs, inclusive of sights. The stock can be flat, or convex, but not concave. The Forearm can be any width and have any angle. The butt stock can have any angle including a reverse angle, the barrel shall not be less that 18″ long forward of the bolt face and can be any diameter or configuration including a straight taper or a reverse taper. The Sporter Rifle can be no larger than .308 Winchester. Sporter Rifles do not have to conform to the Varmint Rifles diagram. All sand bag rules apply to the Sporter Rifle.

Bukys Explains the Thinking Behind the Sporter Rule Change

NBRSA Gene BukysOn Benchrest Central, leading benchrest shooter Gene Bukys discussed the new NBRSA Sporter Rule Changes: “[This] does not create a new rifle or an experimental class — it simply removes most of the restrictive rules from the existing Sporter class. Every existing LV rifle and every existing Sporter Rifle in this whole world is still legal, and competitive, under these changes.

My purpose in all of this is to make the Sporter class, and the LV rifle, no longer redundant classes, and to have a class where we can have some innovation in Benchrest. If there is a better stock configuration out there or a better barrel profile shouldn’t we benchrest shooters be the leading edge of this innovation? Benchrest used to be the leading edge of virtually all accuracy innovation. I’m not sure if that’s true anymore. I would like that to be… true again.

For right now, I don’t see this as making any huge radical changes to benchrest, but given time and a venue to work in (Sporter Class) there may be some really meaningful innovation that comes about. Let’s have some fun with this.”

Gene Bukys Commissions New Convertible Sporter/LV Stock by Bob Scoville
Under the new NBRSA Sporter standards, stock designers/fabricators can now experiment with a wider variety of stock shapes and geometry. Gene Bukys commissioned a new stock from Bob Scoville that shows what can be done under the new liberalized Sporter stock rules.

Gene’s latest NBRSA Sporter rifle features a stepped forearm that can fit a 5-inch wide bag rider plate. In the rear, this stock can run different size/shape “keels” (buttstock underbellies). The larger keel, shown attached in the photos, exhibits the flatter angle now allowed under the new NBRSA Sporter rule. (In fact, this keel may have a slight reverse angle, i.e. lower in the front than in the back). At any time, this Scoville stock can be switched back to a 100%-legal Light Varmint configuration by: 1) removing the 5″ front bag-rider plate; and 2) changing to the smaller, up-angled rear keel piece.
