Not necessarily true, you can't shoot anything below a 55gr reliably with a 1/7, if you shoot a 50gr JHP, or a 40gr ballistic tip, they can disintegrate when fired from a 1/7 because they are over rotated. 1/7 is a VERY tight spin, the only centerfire rifle that uses it or anything close is the AR. Most Use a 1/10, 1/12 or 1/14. The 1/7 was made for sniping with 20" barreled AR's and will stabilize heavier rounds but is only necessary if you plan on shooting 77gr or bigger, if you are, you'll probably want a match barrel anyway.
in less than 5mins i have found that savage, tikka and sako all make HUNTING BOLT ACTIONS in 1:7 & 1:8 223 rifles. many people shoot lighter than 55grn out of 1:7s all the time. you should look at the real reason for the 1:7 rifling - look in the ammo oracle....
as time has progressed the long distance shooters like it for their hevier bullets but that wasn't the original reason for it. when was the last time you saw a 1:14 in 223 and what year was the rifle?
