Does anyone know if the N.C.N.G., or N. State Shooting Club have caliber restrictions in place at Camp Butner? If so what are they and where can I find them in print? Any direction would be a help. Thanks in advance, Waverly McNeill
 
F-Class at Butner

Butch the range at Butner, NC has a 30 caliber restriction. FTR is restricted to .223 Remington or 308 Winchester. F Open allows smaller calibers and larger 30 calibers than 308.

The FTR Police ha ha..

Butch:

The FTR Rules are a combination of the Longrange High power rules with some of their own more specific rules added in.

Taking the liberty to interpret...

The chamber rules in FTR indicate the chamber must comply to SAAMI or CIP specs for the specific chambering (.223rem and .308Win).

The methyodology for checking would be with (steel) go and no go gauges for the rifle and case cauges for the cartridge.

The weight restriction is done with a scale.(18.3lbs for FTR)

I have only limited experience with shooting in large registered matches. I know of equipment having been weighed and visually inspected. I have never seen chambers or cases checked with gauges. It has pretty much been an honor sytem at all of the matches I have attended.

The F Class rules are available on line, NRA, Longrangedotcom and National matchdot com.

So you cannot shoot a wildcat in Ftr? How do they police that?

Oddly enough, F/TR tends to attract people who *don't* want to make the sport into an equipment race - hence most are not too worried about someone 'improving' their cases. Although a chamber on the large end of SAAMI spec (as opposed to most 'tight' match chambers) combined with thin/light brass (i.e. Winchester) can net a small but noticeable increase in case volume while staying within the rules...

Otherwise, it's largely handled by an honor system. Basically unless someone complains, the assumption is that as an adult you can be trusted to play by the rules. If there is a complaint, one way would be with go/no-go gauges as mentioned, although any number of people might have issues with a ham-handed range official jamming a steel plug in their match chamber. Me, as a match director the first thing I'd request is a fired case from said weapon. A quick visual inspection alongside a 'regular' .308 case (of which there is usually no shortage at any Palma/Fullbore/F-Class match) should be able to snag the more blatantly obvious nitwittery...

YMMV,

Clarification "Steel Plugs"

SAAMI requires steel gauges. These are precision ground steel and make contact on the datum line of the shoulder and bolt face. They do not measure the neck or throat. To the best of my knowledge no chamber has ever been damaged by the use of steel gauges. They are the industry standard for checking headspace. Most rifle barrels are made of 4140CM or 416 Stainless Steel. Most Bolts are also made of 4140 or another hard CM steel. I know of no international throat length restrictions. Host countries can set bullet restrictions simular to the Palma rules limiting bullets to 156grains.

Case gauges such as those made by Wilson are a copy of a SAAMI chamber the front is machined so one can measure for minimum and maximum case neck length. The back end is machined to show the minimum and maximum seating depth from the shoulder to the case head. If the case will not fit in the gauge because of the case OD than that is self explanitory.
