One thing to keep in mind also is that you can safely load your 270win to **around** 270wsm velicities. Hornady offers a Innerbond 150 gr bullet with a .525 B.C. Im a huge fan of bonded bullets for the style of hunting I do. At the ranges I usually see and shoot the game Im after you just cannot beat a bonded bullet IMO.
I currently load 140gr Accubonds in my 270wsm, and wouldnt hessitate to somke an elk with them out to 5-600yds. Some folks may push that number farther, but thats where Im comfortable with this load on elk size game.
If you choose to go with another rifle thats cool. One can NEVER have enough firearms
. But dont sell your 270win too short. Its a game getter caliber. Not to mention accurising your current one will help you decide what you want-vs-need to do on your next purchase. Then when you do build, youll have 2 guns that will be accurate and fun that are ''customised'' to you/ by you.
Tank knows his stuff, Id aggree Howa/Vanguard(of the choices listed). But Ive never been a Savage fan. To me, "This aint your fathers Oldsmobile'' and the current Savage vs the old ones doesnt seem any different. Its still an Oldsmobile/or a Savage. But they do have quite a following these days, and theres alot of folks who swear by them. I dont personally know Tank, but after reading a bunch of his posts, I wouldnt doubt that he'd give you good advise, no matter the brand. If Tank likes Savage theres a reason. IMO, Ive never seen Tank steer anyone wrong. And Ive seen him answer and help ALOT of folks with choosing thier next purchase.
To me its a personal preferance thing when I buy a firearm. I like what I like and dont buy what I dont like. Of course when your entire family has owned and shot Winchester for generations, you might be a bit ''bias'' toward what you prefer
Either way theres alot of great advise being given to you from knowledgable folks with experience. So listen close to what everyone has to say, and then wiegh it out and make your own mind up based on what youve learned, and you wont go wrong. Theres great folks here at L/R/H, and not everyone shoots the same ''brand'' but most all of us love our firearms and know them intimately.
Best of luck with your choice.
