I've seen three strands to the 'Let's change F/TR to something better / what it was meant to be' argument.
The first is very much a US issue, rarely heard in the UK and Canada, Australia etc - why do we have this strange choice of 223/308 only? Here in Britain, it's the one thing that F/TR's critics actually like. The point is that F/TR is an offshoot of TR / Palma Rifle, is regulated by ICFRA and these are the cartridges for mainly historic reasons. FWIW, I think it's turned out to be a good choice as both cartridges are enormously popular outside of China and some of the former communist countries so development in the hothouse F/TR environment is facilitated and benefits other users, and components are widely available in most countries. The only downside is the link to 5.56/7.62mm military calibres and the restrictions this places on some European citizens whose governments simply don't allow civilian use of 'military calibre rifles'. For instance, it's very difficult for Spanish shooters to own a 308, but we still have a surprising number turn up at Bisley every year for the European Championship meeting. Back home I understand they've developed .222 Rem with fast-twist barrels and heavy bullets for 300-600M F/TR as owning a 223 is impossible. We may face future UN led challenges to ownership and use of 308/223 in the guise of 'international smallarms control'.
The 'arms race / money buys points' argument. We have a fair size group of people in the UK who want to challenge F-Class on this basis and are promoting S-Class (Sporter Class). To make F/TR affordable, factory rifles only, very limited modification allowed, tight and low weight limits, must have a working magazine in situ, limits on scope power to 12X (or 16X, (or whatever X as every proponent has a different view on this matter) and no fancy bi-pods. The F/TR bi-pod is the hate object for many here encompassing everything wrong with the discipline and in their proposed class the bi-pod would have to have folding legs and fit inside a box with limited dimensions. There has been vast amounts of talk and discussion on ranges and some forums, but so far as I know nobody has instituted a true S-Class to date even for limited club shoots. I've tried to promote the 'affordable rifle concept' starting with secondhand sporting rifles (Savage 12 LRPV rebarrelled to 223R for 90s and an as issued Howa 1500 Varminter in 308) and used them successfully / written about them in TargetShooter online magazine. But the critics aren't interested - if it's not 'their class' they don't want to know. There is a view that says any discipline has those, thousan ds of them in fact, who would compete ..... if only X were changed ........ but that sensible regulators should ignore them as they never will compete seriously. My personal view is that you can get into F/TR with very modest kit and have a great time and fair success, but you can't regulate the kit used at national or international level to suit impecunious tyros. Being at the top of ANY sport is expensive even if it's training, travel, and accommodation costs rather than equipment.
Again. these people either don't see that F/TR is a high-tech higher-precision offshoot of Target / Palma rifle, or if they do, like it even less. They are the same people who for years have criticised 308 sling shooting in often very insulting terms - suitable for 'anally retentive types' only, not real shooting, not real rifles etc .. etc. (The words 'not real' keep cropping up in the anti-TR and F/TR lexicon.) Unlike many, I've no objection at all to their owning and using M1913 MILSTD rail festooned black or camo-finished rifles that look as though they had been killing Taliban in Helmand Province recently, but why should they think their rifles are a) 'real' and mine are not, and b) superior to mine, likewise the use they put them to?
The final argument is that F/TR isn't what George Farquarson intended - this wonderful idea has been corrupted by the purveyors of custom rifles, Berger Bullets and its 230gn Hybrids, makers of carbon fibre bi-pods. It should be somehow restricted to 'what George intended', so (presumably) 155gn bullets, thinner barrels, cheaper / cruder scopes and bi-pods. I don't know how the late George Farquarson would regard today's scene and neither do they. I reckon they want to preserve something that developed in the 1990s (?) in aspic, and no discipline thrives in that environment. Over here, we suffered for decades from people who reckoned the move from the Number 4 Enfield rifle and .303-inch cartridge that in arsenal form struggled to better 3-MOA to Target Rifle and 7.62mm was a sin against God. These were the same people who regarded the UK L1A1 (FAL) service rifle that replaced the No.4 as an abomination in civilian hands and under no circumstances would follow the US NRA in retaining SR disciplines with constantly developed and accurised versions of the nation's military rifles - and look where that got us, we can't even own them now at all, 'Section 5 Prohibited Weapons' is the legal designation. Yeah, you guys in the US, really f+++ed up there - M1As and AR15s in competition really set your shooting sports back generations didn't they? Sorry if I sound bitter - but I am!
