Jerry and Maynard,
A good buddy and I talked this over alot today after an outting at the range and we basically concluded and both believe that for a rifle to fit into F(M), it should be a rifle that
* you do not have to special order from the factory
* has a factory mass produced action, barrel, stock and trigger
* is not made in the factory's custom shop
* this class IMO should NOT have a bullet weight limit or caliber requirements and is for the true beginners, using the old Parker-Hale 243 or 6.5x55 or Enfield 303 or whatevers, so the sport grows and we get more new shooters out...
I think once you change anything (barrel/trigger/stock/Action/rechamber) IMO, as Maynard said, you are in F(F), but you have to use a 308 or 223 and meet rifle weight and bullet weight requirements or 155g or 80g so the BC's are equal and it's shooter against shooter.
That said, there are a lot of presummed "factory mass produced hunting rifles", like the new Savage FClass rifle, 40X, Tikka (Sako's cottage industry custom shop) T3 or the older LSA-55 Heavy Barrel, Savage or Rem or whatever with a special non-factory barrel (i.e., Hart, Shilen or Lilja etc) or non-factory trigger (Jewell etc).... even if you did buy it off the shelf at your local gun shop(since they ordered it in speculation), would all fall into F(O), kind of like a Borden "Walk-Around" Varmint Rifle or a Borden Standard Hunting rifle, which too looks like "normal, off the shelf hunting rilfe", would be in F(O). Also, IMO, if you do not make the bullet weight restrictions for the 308/223 of 155g/80g, again, your in F(O). This is the way I see it anyways
