At the time of the origin of "F" class, there was already a class called TR-O (target rifle-optical), which was seldom contested. Also, for a period of time, there was the option of using a 4x scope instead of iron sights.Quite so Boyd. What Americans have to remember is that British Commonwealth 'Target Rifle' (sling shooting) is entirely iron sights. (UK, Canada, South Africa, Australia, New Zealand.) There is the any sight 'Match Rifle' variant, but that is a minority discipline that is shot with 308 at 1,000 / 1,100 / 1,200 yards.
So UK and Commonwealth sling shooters faced enforced retirement as soon as their eyes deteriorated to the point where they couldn't get a good sight picture with conventional match aperture irons. There was no equivalent scoped rifle discipline.
George Farquarson envisaged and invented a modified TR rifle formula, basically a single shot 7.62 TR rifle continuing to meet ICFRA rules on things like (1.5kg) minimum trigger pull, and maximum weight was determined by the TR + ICFRA rifle maximum plus a Harris type bipod plus a decent target scope and still shooting on standard GB NRA / DCRA fullbore targets (2-MOA 5-ring / 1-MOA V-Bull) so that he and the many others like him could continue shooting competitively in what was a sub-class of their former discipline. TR and the new F-Class participants continued shooting mixed together as they used the same targets. (This was the case when I started in F, the only difference being that in the UK anyway, a V-Bull scored 6 points so we shot for 120 points HPS, not 100.20v.)
Since George's day, TR rules have been amended to allow optical lens type enhancements such as the Eagle Eye to apertures to extend the shooting life of older participants, but that was for the next generation of shooters, and even so many older shooters still struggle to continue.
As the discipline caught on and was adopted outside of Canada it was amended to create what we now call 'Open' class - any calibre, any trigger pull weight as long as safe, front-rest support, 22lb all-up weight. The 223 Rem and 308 Win F-Classers soon found they were hopelessly outclassed against a weird and wonderful range of very high MV / high BC cartridges with 6.5-284 soon rising to prominence. The NRA target quickly proved to be too easy - the (true) saying soon arose that the first shot that leaked out of the V-Bull into the Bull-5 ended your chance of a high match place. So, F/TR with a lower all-up weight; 223/308 only; bipod instead of frontrest was introduced and target ring diameters were halved compared to the NRA versions. The discipline morphed from Farquarson-Class into Free-Class allowing experimentation and innovation within a fairly wide set of parameters. I personally think that on balance this was the right move as F-Class has driven greater change and innovation and increased standards of precision etc far more in the last 10 years of my shooting experience than the previous 30. It also brought in younger participants who simply would never have adopted a discipline that saw them trussed up in leather jackets and saddled with a tight sling and restricted to iron sights. The downside is that higher standards / fancier kit increased costs, and not everyone wants to handload.
In the UK many clubs successfully added a factory rifle only class, but it has generally either failed after a while or been restricted to modest numbers. F-Tactical / military, call it what you like, has in the UK anyway seen greater enthusiasm, largely because the various tactical disciplines. and now PRS, have caught on in a big way and people are having very good rifles built for them, using very high quality glass etc which shoot just as well in single-shot prone comps. Many of my club's tactical shooters now have a match every weekend when you include F and even get two matches into a single day (mid range F fixtures usually have a 200/300 yard McQueens comp on a parallel range, so they book in to one match in the morning, the other in the afternoon or vice versa which we can manage with e-targets not needing large butt crews).
Anyway, when George envisioned "F" class, he not only wanted to extend the competition life of older shooters (most of whom did not take up "F" class, by the way), he also wanted to bring shooters from other disciplines (like me and some others) to TR venues. His hope was that some would become interested in target rifle shooting. George was not just a fine shooter but he was a rifle enthusiast. He wanted people to be able to use different cartridges (George got one of Canada's first 7mm-08's). He, Art Bourne, and Bob Hobbs were some of the early competitors. My Dad took it up just to compete with Bob Hobbs, I suspect! They were friends but competitive ones. I started shooting "F" just because I knew all of these guys (I worked with Bob Art, and George) and I had grown bored with BR. I like building rifles and this was kind of a good excuse to build more.
My first "F" class match was fired with a 6BR built on a model70 target rifle, for Bob Hobbs. I was just testing the rifle. I had only loaded enough ammunition for one day. As it happened, I was reading things pretty well that day and was well in front at the end of the day. I declined the offer of a loaner rifle from a friend and chose to leave on a high note! I then repurposed a 6.5x55 (another Model 70) I had put together for 1000 yd shooting and shot "F" for quite a while. Later, I switched to shooting TR-O (optical) and enjoy that more. "F" had become a little too much like BR without the bench.
I shot a couple of TR matches with a 4x scope but the DCRA stopped allowing that so that ended my TR efforts. I just didn't want to spend a bunch of money on iron sights when I had a drawerful of scopes.
I still believe that the original F class rules covered everything pretty well. Right now, muzzle brakes are not allowed, and I see no reason they should be. Every muzzle brake I have installed, every one I have made, was either removable or capable of being deactivated. Easy peasy.
I think even F/TR should not have happened. I think the maximum weight should simply have been reduced and that's that. I don't know if I will shoot "F" again, but if I do, I just be sure to be within the rules and enjoy the small successes as they come. WH
