the tr class only allows 308 or 223. what about 30-06??
Ron,
To understand that, you need to understand some of the background behind the sport.
Outside the U.S., many of the countries that form (or formed) the British Commonwealth i.e. Canada, Britain, Austrailia, and others shoot a form of iron-sight long-range Prone competition that is very similar, but not exactly the same, as what Americans outside the sport tend to lump together as just 'Palma'. In Canada, one of the categories is known as 'Target Rifle', or just 'TR'. Guns are limited in that class to either .308 w/ a max of 155gr bullets, or .223 Rem with a max of 81gr.
When F-Class got started, it was essentially 'run-what-ya-brung', i.e. everybody shot together. In many areas with small matches, it still ends up that way. Over time, it got divided into two areas - F/Open, which is pretty much still 'run-what-ya-brung', and F-F(Canadian) or F/TR (American), which retained the caliber limitations of conventional 'TR'. Part of the reasoning is that on paper a .223 Rem w/ a long 30" tube, slow powder and a 80gr bullet should be roughly equivalent to a .308 Win w/ a 30" barrel and 155gr bullets. Whether they *are* equal is a subject of some debate, but personally I don't think one has a *huge* advantage over the other.
The .30-06, while a grand old cartridge, is not equivalent, and is not a normal TR (or even Palma) cartridge. A purpose built rifle slinging 210s (or heavier) from a long barrel would be significantly ahead of the power curve in F/TR. If you want to go that route, nobody is stopping you... but you'll have to play in the deep end with the sharks in F/Open.
May not be what you want to hear, but thats my take on it. It's a game, those are the rules. You can like them or not, it really doesn't matter.
YMMV,

Ryan,
F/TR has a weight limit of 8.25 kilograms... about 18.15 lbs for us yanks. That includes *everything* attached to the gun - scope, bipod, sling, whatever. If you pick the gun up off the ground and a piece/part comes with the gun... it gets included in the weight.
As an example... my relatively stock 12 F/TR with factory 30" tube, laminate stock, NF 12-42x BR scope in Burris Signature Zee rings, Harris BRMS 6-9" bipod with Pod-Loc and Pod-Paws weighed in at 17.5# at FCNC. The Pod Paws are surprisingly heavy - 0.33# just by themselves.
Having shot a bit of conventional Prone (i.e. 30" barrel with iron sights and a sling)... I think you definitely *don't* need a big heavy barrel that looks like someone jacked a drive shaft off a semi A medium Palma contour works quite nicely, and its entirely possible to shoot pretty well with a light Palma contour. A fluted heavy Palma contour might be my choice if I was building from scratch... about the same weight as a med. Palma, but a tad stiffer.
Think of it this way... every ounce of weight you use up in your barrel is an ounce closer to being over the limit, and muzzle heavy guns are harder (for me at least) to control in the bags. There's definitely something to be said for a well balanced, well behaved gun that tracks nicely in the bags.
The .308 is blessedly not that finicky when it comes to twist rates. A 13 twist might be a *little* better for 155gr bullets, and a 10 twist might be a *little* better for 190gr bullets... but a 11 or 12 twist should shoot dang near anything in between with no problem.
YMMV,
Monte
Not currently in the U.S. Other countries (like Canada) may.
Do you have a FTR Class gun?
