I have a full stock, in 7X57.
You need not worrry about the accuracy. the trigger is easy to adjus and I shoot better if I don't use the set.If you want a full stock, I would not choose the 30,06. I think the 20.5 inch barrel would be a better platform for the 6.5 or the .308. I wonder how it would preform with the 9.3X62. Mine points quickly and handels great. The 9.3 would sure be a great close cover rifle for big critters. Elk moose bears. Mine has a VX2 2X7, a good combo...tj3006

The "close cover/nasty critter" rifle element was part of the rationale for the 9.3 X 62, but the other (and somewhat conflicting) factor was its possible utility as a cast bullet rifle--which is its "range rifle" persona. It was this range usage element that decided the "Lux vs. F/S" question for me.

The Lux is not a very heavy rifle, and I suspect the F/S might be a bit lighter. With full-on 286 grain bullets at 2450 FPS, it lets you know the primers functioned from benchrest. Shot from standing position, the recoil is quite comfortable--but when seated, it's not a lot of fun.

The caliber is an absolute delight with cast bullets. I run the 270 grain Mountain Molds design with 18.0 grains of Alliant 2400, providing about 1600 FPS. It will average just over one inch at 100 yards......five-shot groups are round and consistently land between 1.25" and 1.5". Three-shot groups and ten-shot groups do about the same thing, so it's a real steady load in my CZ. These same bullets at 2000 FPS open up a bit, to about 2" @ 100. It is as a cast bullet rifle that I really enjoy this caliber and its platform.

I had a FS hog backed .308. The drop at comb was too low for me with the CZ scope rings that I purchased from the dealer. When sighting it in it took forever for the barrel to cool off between 3 shot strings. The scope rings were high so the scope could clear the bolt. I passed it on. Jimmyp

I have a FS in .270 that works great. Used Burris CZ rings and a Burris 3-9x40 and S&B 150 gr. for 1.5" groups at 100 yards. Bolt handle clears fine. I wanted a 6.5x55 but couldn't find one.

The CZ 550 FS in 6.5 x 55 shows up on the company's main (I guess you could say European) website but is not listed on the US website. I'm guessing you can't get them in the US unless they're listed on the CZ_USA website. I'd sure like to think they would be made available here in the states, if CZ is making them anyway.
