All the Remington .260's were introduced with a 10 twist when they brought the cartridge on to the market and the caliber never gained popularity. I don't know if they made a model seven in .260 when they first introduced it or not. I think the following year they went to a 9 twist and things were better but the caliber still didn't really take off.
260's got super popular when some of the other rifle manufactures like tikka and sako and savage pretty much everybody but Remington and browning started making their 260 barrels with an 8 twist.
Crazy how Remington keeps screwing stuff up. I would think a lot of people would shoot a 6mm Rem instead of a 243 if Remington had ever offered it with a fast twist barrel so it would shoot 100 grain bullets well.
Sorry to derail your thread trox. I love model sevens and .260's so I just thought it was interesting
I'm anxious to see how this 10 twist A-bolt is gonna shoot the 100 grain Barnes TTSX heated up. Even if it doesn't shoot it well, it won't be a big heartbreak or anything because it will shoot a ragged hole with the 120 TTSX factory stuff. For whatever reason, when I think of a 140 grain bullet...I think 7mm and not 6.5 though I certainly understand why many folks do want to shoot 140 grainers in a .260.
I did shoot some 140 grain Game Kings (Southwest ammunition) out of that little Browning the other day and though the group wasn't nearly as good as the 120's, it still shot them pretty damn good. Very interesting to look down through the history of the .260 and study the twist rate issue, load for the .260 now, etc. I'm looking forward to fooling with all of it a little more myself.
