A 10lb rifle doesn't bother me, but it bothers a lot of folks. They are godawful heavy for what they do, a 5 shot iron sighted (or awkwardly scoped due to very high mounting) rifle. For the same weight in a bolt action you have a bull barrelled precision rig ("sniper" for the new generation) with a big scope on top, instead of a pencil barrelled .308 with iron sights. They won't bring you any advantages, as they're less accurate than good bolt guns, heavier, have poorer scope mounting options, and are restricted to a smaller range of ammunition choices.
This all said, they'll kill game just as well as a $15,000 custom Krieger barrelled bolt gun as likely 90% of the game in Canada is shot inside 100 yards, and often just barely further than that from the ATV or truck so rifle weight doesn't mean a ton. All my criticism aside, I also love the M14, just not Chinese versions but that's a personal choice on country of origin and who I want to support. They have great lines, very natural iron sights, and give at least functional accuracy if you're not comparing it to your bolt guns. Recoil is very soft due to their porky weight and semi action, and they are one of the last great "wood and steel" military rifles (not the Norcs however, the Chu wood is atrocious).
If it's a gun you're attracted to, it's no different than commuting to work in a '67 Fastback, it's a classic and part of the enjoyment comes from seeking out and using something different you enjoy even if there are faster cars out there. I hunt with a 1924 Oberndorf Mauser a bit, there are better bolt guns, but I enjoy using that one. M14's are the same, know their shortcomings and just go have fun anyway if you like them. I'm looking to build an LRB or buy a nice Springfield M1A myself at present.
