Asking because local BellasProAss actually has a Savage 110 Tactical Southpaw in 6.5 Meme. And guns in the handedness of Gun Judas are fucking hard to find even in the best of times. But is Mememoore just a fad that is already passing with the PRC's being the new hotness? I know it has seen limited adoption by the military, and my grandpappy said buy shit the military uses, but by army guys who have personal ammo budgets higher than the entire yearly budget of my local sheriff's department. And they can change on a whim should "the mission dictate".
Normally I'd go with .308 because I already stock it for the Cold War Rifle collection, or at least Full NATO. I've avoided Mememoore because if I had followed every trend I'd have a .260 Remington, 6.5 Grendel, 6.8SPC, all of which was to be the next big thing then faded.
I could ask long range shooters, but they're kinda assholes plus sniff the manufactures and guntubers/bloggers farts. Figure autists would be the better perspective.
Honestly man, as a fellow southpaw, learn to manipulate right handed guns. You'll save money and in the large ice house chances are any rifles you may pick up off of dead minecraft creepers will be right handed (in minecraft). You'll want to work up that muscle memory.
I've done the right handed thing with Lee-Enfield's, 1903's, 1917's, Commercial Mausers, cheap Axis & T/C Compass rifles, and old .22 bolt guns, etc. for 40 years. Wasn't a really a problem with open sights/iron sighted guns, but as the eyes get older and the need for scopes become a thing...yeah I'm buying something to fit me.
