Answering your queries Adrock ... firstly all Remington 700's have free floating barrels ... some "info" on the site may highlight this feature on certain models and on others it is silent ... but if you look at the owners manual and the blown out diagram on assembly part numbers you will see that on all models the barrel floats freely from the action and you would be able to get a dollar bill and fold it over the barrel and run it down to the action ... do this on the model you are interested in before buying though to test and make sure the stock has not warped or been attached out of true ... if the bill catches on the side of the stock reject that rifle and ask them to order another ... they ARE meant to have free floating barrels and the stock should not be touching the barrel ...
The next thing is the difference between .308 and .30-06 ... in the 700 Remington use a 1 in 10 twist in a 30-06 and 1 in 12 twist for the hunting models in .308 and 1 in 10 twist for some of their tactical models in .308.
The twist rate determines the way the barrel is able to stabalise bullets ... the lower the twist number the faster the twist ... so 1-10 is faster than 1-12 meaning it turns a full twist every 10 inches of barrel as opposed to 12 inches ... so it spins the bullets faster and heavier bullets need to be spinned quicker to stabalise them as they usually are longer given that the calibre is a constant ...
Some calibres with smaller diameter also use very long bullets so have an even faster twist ... an example is a 6.5 mm calibre which usually has 1 in 8 ...
So in most hunting models the 30-06 will handle heavier bullets better ... by heavier I mean 180 grains plus ... going up to 240 grains ... the sort of weight you would want for large game ...
That's not to say a 30-06 in 1-10 will not handle lighter bullets if you wanted to use them ... in theory ballistians talk of faster twists on lighter bullets which may not need such a fast twist as causing them to "over spin" and turn slightly "nose up" the effect being called "surfing" ... but this is "theory" only and in a 1-10 twist a 30-06 shoots lighter bullets just as well as a 1-12 twist barrel ... or put it another way ... if the barrel is a good one it will ... Remington 700's vary a great deal on what the barrel will do ... some are better than others and it is a bit of a lucky dip ... but all are generally good enough and should certainly be adequate for hunting ... tweaking a load for an individual rifle is all it takes .... if you don't re-load then all you need to do is try a few different ammo makes until you find what works best ...
The length of action is relevant only on issues of dangerous game in a hunting rifle ... the Remington is a "push" bolt/magazine pick up ... the longer the action/bullet the more likely a jam occurs when cycling fast for a follow up shot ... that is why African dangerous game rifles are usually preferred with a Mauser bolt which picks up the round on the rear stroke and loads it into the barrel locked into the bolt face so it is perfectly straight and lined up ... the Remington slides the round up the ramp so smaller is better ... but the 30-06 is at the small end of the long action rounds and usually chambers just as well as the .308 if you have a practised and smooth bolt cycle technique ...
Rigidity of the action is only going to be an issue in top end target shooting ... not relevant for hunting ...
What is relevant for hunting though when choosing a model is weight and whether you go for a magazine or a drop floor plate model .... my advice is go for a magazine model as when it is cold and you work in gloves unloading a magazine is far better than dropping out the floor plate ... this usually ends up with dropped rounds in the snow and when wet rounds can cause chamber pressure risks from the water instantly evaporating with the explosion of the powder ... a magazine therefore works much better for me ... and weight wise ... if you are able to have a light rifle it is a bonus on a long day ... recoil is not an issue in 30-06 if the rifle fits well ... fit is more important than weight ...
The length of pull on a 700 is really too short for most blokes ... they go for an "average" which includes women sizes ... most guys are on a 14 inch plus L.O.P. ... the 700 is about 13.5 inches .... look to see if you can order one with recoil pad spacers added to make your ideal L.O.P. ... they should be able to do this or if ordering from a good gun shop they should do that for you to get the deal ... if they don't know how to measure your L.O.P. walk away and try elsewhere ...
Personally I would consider an incline rail as an addition to the action to put the scope on ... it tightens up the action and there are loads to pick from .... accessories for the 700 are one of it's perks ... Badger do a good one ... and then you can use military picatinny rings to really lock in the scope ... bashing the scope when carrying the rifle is one of the most common reasons for flunking a shot when hunting ... so a strong set of scope rings makes sense ... a 20 minute of angle rail will also make the most of using the 30-06 out to it's full range capability ... handy if you want to use lighter bullets and do a bit of varmint shooting ... the new 155 grain Sierra VLD match bullets work really well here ... and getting into re-loading will help too ... but if you buy well at the start ... all this is open to you to explore later ...
Triggers can be easily changed out too if you want to at a later date ... but match triggers are not really needed on hunting rifles ...
Let us know which 30-06 model you were thinking of ... then a more accurate bit of help can be given ... and definately go for a .30-06 over the .308 for Alaska as the average bullet weight you will need will definately favour a 1-10 twist :thumbup:
Man... it takes coming to a knife forum to get some good rifle info.

I wont argue with you due to my lack of experience with the 700, but according to the guy I spoke to at Remington, only certain models come in the "free float" variety - meaning the barrel leaves the receiver and never touches the stock. (like the dollar bill method you're describing). He said several other models have two pressure points where the barrel actually touches the stock intentionally for sound resonance purposes.
I have been focused on the detachable magazine varieties as a possible criteria. It seems to make sense to me for all the reasons you listed, but again is not available on all models, so you are forced to choose "certain" features over others
I haven't narrowed it down too much yet. I was first trying to narrow down the chamber, being that that is another "option" which forces your selection. I am interested in some of the SPS (special purpose synthetic) models or any model with a synthetic stock. I think wood looks best, but in trying to select a go everywhere, do everything rifle, synth works better.
I guess I need to take another look at the list and see where it lands me if I plug in:
30-06
synthetic stock
detachable magazine
Excellent info Peter. Thank you for the input.
You seem reasonable in your selection and I know you aren't locked into a free-floated barrel. Still I am impelled to ask the group, just what advantage does a free-float barrel have on a hunting rifle over one with the barrel properly bedded in the stock? Practically speaking, I mean missing the kill zone on a sub-300 yd shot.
I am a big gear nut, and when I was rifle shopping I had more extreme ideas. I decided I needed a Remington R5 (never got one) because that's the best sniper system without going custom based on what I read. After years of reading forums for "expert advice" I realized that much of the must-haves are really superfluous in reality. All the special tactical features are more of a hindrance for hunting. I want some light, dependable, and accurate enough (groups of 2MOA are more than enough).
I'm trying to be reasonable. All too often I get caught up in a myriad of "wants" that cloud what is most important, and then in the end I'm stuck with something that does a little of everything, but nothing WELL. Its my understanding that a free float barrel wont contact the stock, should the barrel swell and move due to changes in temperature. My Stag 2T AR-15 has free floated rails adhering to this same principle. Its also semi-auto and shoots paper all day. According to Remington Rep Guy, free float is no big deal on a hunting rifle. Its nice, but falls into the overkill category.
Its funny you mention "special tactical features". I was all caught up in a tactical HD version of an 870 that would double as a hunting gun. It has all the bells and whistles - Ghost rings, 6 round mag tube, smooth bore 18" barrel threaded for chokes, factory Picatinny rail...etc. Trouble is, all those features actually impede its hunt-ability (go figure
