when I got them, I had both of my Ruger 260s throated out to accept a 160 grain Hornady RN, with the bullet seated to the cannula...so mine are not factory throats anymore.. which were kinda tight...

I did that to both of them about 2 weeks after I got the first and as soon as I got it home on the second one... which I got mega cheap, because the store had had it for over 3 years and it never moved... well under $300 for it... stainless, laminate stock...
