All-time favorite 270 win in a 1955 FW rifle most used center fire rifle I own. Rifle has been rebarreled FW Douglas XX. This rifle still has factory stock that has been reworked completely (RJ Renner Sparkes NV). I have used it since early 80s. I had a pre 64 FW 30/06 with bad barrel rebored to a 338/06 still has factory barrel just rebored. A great caliber for elk and bear on west end WA state. But I reverted to my old 270 this year for deer. I also have a Cliff LaBounty Rebore in pre 64 model 70 a 300 H&H rebored to 375 H&H. It's like a FW 375 H&H. Not a rifle you go shoot 3 boxes of shells with at the range. You have to carry it all the time only shoot it once in a while on hunt. 338/06 and 375 H&H both have composite stocks. 375 with scope and loaded less than 9 pounds.
Really though I could have saved a lot of money and time and done most everything with 270 Winchester. I have had sold traded a bunch pre 64 model 70s along the way. Need has nothing to do with it. I had a lot of fun. For a set or rifles and calibers to use and travel North American, world with 270 Winchester, 375 H&H would be my choice. A 30/06 may be a little more common since choice for travel. But after 40 plus years I shoot my 270 really well.
270 Winchester.
