well if you shoot on a team and thats all you shoot then you should be able to tell me most anything about them.
Dunno about that. I *shoot* them; I don't get all into the trivia business that some folks do, but I'll try.
what the diff in the 10 and the 12 models?
Functionally, between a model 10, 11, or 12 repeater? Nothing. The 10 series tends to be more LE/Tactical, the 11 tends to be more big game/hunting, and the 12 tends to be more varmint/target in terms of features like stock, barrel contour, caliber options, finish, etc. If you look on their website at a 10FCP vs a 12VLP you should see what I mean. Mechanically... no meaningful difference. The Target Actions have some mechanical differences (small ejection port, most models are solid-bottom single-shot actions, etc.) that may aid in accuracy.
what exactly is the diff in the bolt? didnt quite follow all that.
Same here... not really sure if you're responding to my stuff or someone elses.
also how are these rifles bedded from the factory
Varies wildly on the particular model. My 10PC-SR (20" .308 Win) is in an AccuStock (thin plastic stock with an aluminum spine that is supposed to stiffen it up some. My 12LRP (26" 6.5 Creedmoor repeater Target Action) is in a fiberblass HS Precision stock which IIRC has an aluminum block. My 110BA has a solid aluminum chassis. My 12 F/TR, 12 F/Open, and 12 Palma all have wood laminate stocks with pillars, and have been skim-bedded afterwards to boot.
I like the looks of the 10fcp-sr but i really like the feel of the mcmillan stocks.
So order a 10FCP w/ McMillan stock, get the muzzle threaded by your gunsmith, and if you feel the need, order the bottom metal from CDI Precision. AFAIK, its the same stuff used by the factory, takes AI mags, etc. and then you have the stock you like, barrel threaded for a can, etc. You can get it done in stages if you want, to spread the cost out a bit.
