I personally don't see it as a potential heirloom even if could last that long and how many barrels do you think you'll have to put in it?
it is in no way a heirloom and i am not at all a die heart savage fan just saying a savage is a much better gun that should last longer then the 710 and as far as how many barrels do i plan on putting on it? as many as i want to

lets say next year remington drops the 710 from their line. your barrel wears out but you love that 710. guess what you CAN'T replace that barrel

sorry. so now your great rifle serves no purpose. and IF all the 710's are as great as yours you won't be able to buy a used one because noone wants to get rid of theirs. now you can get a new rifle but geez that 710 is only a couple years old.
I'm not sure where all your hostility toward the 710 comes from. If you could quote the source of your information perhaps that would help me to understand where you're coming from
well some of my hostility comes from the facts above. and almost all of my information comes from first hand experence. i have handle a 710, i have shot a 710, and i have cycled their actions. the bolts are very loose and sloopy. i hate the way they handle because the stock is crap and i couldn't get a good grip on it when i tired. they don't shoot too bad but they certainly didn't break the sub MOA very often at least not the two i saw. one shot on average 1 1/2 inch the other held just above 1 inch some times and others shot 3 or 4 inch groups.
And as far as a rifle you can use all your life and hand down to your son who hands it down to his, well I think it'll be interesting to see how the 111FXP3 holds up
well lets see when my stock falls apart 20 years from now i can replace it, when my barrel is shot out 3-5 years from now i can replace it, when it is still shooting sub MOA 20 years down the road i will be very happy with my purchase. and like i said the 710 is only half decent until it falls apart. then you either can't fix it, or can't replace it.
just my .02 cents however don't think i don't know anything about the 710 because i do
