Bill,
Yes and no...
Yes, there are two classes of F-Class... F/TR and F/Open. F/TR stipulates a caliber limit (unmodified .308 or .223 - tight chambers okay, but no Ackleys), a lower weight limit (8.25kg, or about 18lbs 3oz.), and regulates the method of supporting the rifle (bipod or sling, plus a rear bag). The 8.25kg includes the weight of everything attached to the gun... including the bipod/sling. F/Open has very little restriction... under .35 caliber (less depending on the range facility), 10kg (22lbs) weight limit, 3" wide fore-end, and front rests are allowed. The weight limit still includes anything attached to the gun, as some folks up north (Canada) use a rather nifty ski/bipod system that almost rivals a traditional front rest (and it better, for the price - $400+ U.S.). Also, no mechanical rear rests allowed, no tables (includes little 'tables' setting on the ground w/ 2" legs, yes it's been tried and shot down), and no one-piece rests.
Muzzle brakes are not allowed under either version, though a lenient local match director *may* flex on that one and stick a braked shooter down at the end of the line where they don't bother anybody. I really wouldn't count on it unless you know the match director *personally* as a lot of them are 'conventional' High Power shooters and brakes offend their sense of whats right and fair. Trust me, about the time you get squeezed in 6' apart w/ brakes on either side of you, laying on a gravel/sand firing line... you'll understand *why*
And for the 'No'...
No, High Power and F-Class are not separate entities. I keep getting this line of B.S. (pardon my french) from people... 'Such and such isn't in the F-Class rules'. News flash: There is a reason the F-Class rules are numbered '22.xx.xx'... because they are part of the larger set of NRA High Power Rifle Rules. F-Class is an extension of conventional Prone High Power. The rules are the same, the scoring is the same (albeit a slightly smaller target), the procedures are the same, and the sanctioning body is the NRA... not the NBRSA or IBS. F/TR is *specifically* intended for ex-Palma and TR (i.e. Commonwealth Fullbore 'Target Rifle') rifles and shooters. Thats where the caliber limits stemmed from. Fullbore/Palma rifles do *very* well in F/TR... enough so that a while back a bunch of whiners (mostly tactical shooters) wanted to limit the barrel length in F/TR to 26". Somehow they thought those extra 4" of barrel were what was whipping their butt in the wind... not the 20+ years that the shooter behind it had *reading* the wind.
Matt,
If you go to the state R&P assoc. page, click on 'Disciplines', then 'High Power' you should see a couple links of interest. One, of course is the
link to the F-Class page (which I maintain, being the 'representative'
for F-Class & Tactical matches). The other is the link to download the yearly match schedule in PDF format. You might d/l and open that and look at how many matches are labeled 'Prone' and/or 'Palma'. Pretty much any of those you can go to and shoot F-Class. At some, you may well be the only 'F-er' there. At others... there may be as many as a dozen - which typically constitutes anywhere from 1/2-1/3 the total attendance.
There are some parts of the country where they have sufficient critical mass to have stand-alone F-Class only matches with 30-40 shooters (supposedly), but around here, 8-10 is a good turnout. I'm trying a F-Class only 600yd championship next weekend; we'll see how the turnout is. The timing could be better: it's going to be warm, it's awful close to Nationals, and another range which normally has a loyal following on the 2nd weekend of every month changed this month and nicked 'my' weekend, and we actually have wind on this side of the mountains
so we'll see how many people put their money where their mouth is as far as wanting F-Class only matches.
Probably the single biggest gripe I get from folks is the F/TR vs. F/Open match up. Generally most match directors implement a five-competitor minimum for each 'class'. Less than that... gets rolled up into the next higher inclusive category. It happens all the time... a lot of Prone matches have a 'High Master' class, and a 'Combined' class w/ everybody else as there isn't any other way to class up 2 Masters, 1 Expert, a Sharpshooter, and a Marksman without bankrupting the match budget. Same thing for rifle classes... usually there *isn't* any division in smaller matches between Any Rifle, Match Rifle, Palma Rifle, or Service Rifle. But F/TR shooters get all sorts of bent out of shape about getting lumped in with F/Open shooters... "But I'll never be able to win..." Sorry, about the only thing that can be done is to go recruit your buddies to come and shoot. Get five of you to come out and make a class so you can get awards (may not amount to much more than a gold star) or else just worry about your own shooting and work towards the big matches where there are enough F/TR shooters to whip up on
