I'm happy you are pleased by their offerings.
Tactical is relating to things carefully designed to get a specific military end, according to my online dictionary here. True tactical in a Scout rifle then would be an 18-20" barrel. Short enough for plenty of handling ease for anyone taller than a hobbit without sacrificing all the ballistics you can legally sacrifice to a short barrel. It's all marketing so I suppose it makes good business sense. M-4 length and threaded for a suppressor. Tactical marketing.
Every inch you take off the barrel of a .308/7.62x51 past 18 or 20 inches becomes an extra reason you should've just gotten a x39 when you start crunching all the numbers. I'm not obsessed, I'm irritated that I go browsing Savage bolts and all of them have less barrel than offered in the past. My complaint is the same sort of complaint I harbor against their "regular" length barrel. It's a joke to me that most of the magnum caliber models are being offered in 24" barrels instead of the previous 26" until I realize their target market has become dudes coming of age during Obama era guns i.e AR-15 gun grab buying craze who maybe don't know any better. The hobbit rifle will be be their first bolt action. They are the tactical obsessed guys Savage is selling too. Right now my only selection for a 26" heavy barrel 7mm mag has a tree camo stock and a brown finish and costs more money because of the clown colors. Maybe in a few more years they will come to their senses.
