Okay.Let's talk about Sako L57 and L579 in .244 Rem
There would have theoretically been eight different configurations of Sakos in .244: L57 in Standard Sporter, Heavy Barrel, Deluxe Sporter, and Mannlicher; and L579 in the same four configurations. I own or have owned four of those (L579 Standard, HB, and Deluxe, and L57 Standard.) I still have three of them, so will take a photo and post it when I have a chance.
Considering how relatively few .244's were made in total, some of the scarcer configurations might even qualify as being "rare".
I'm not sure the exact twist that Sako used on these, but it was apparently metric and a bit faster than the 1-12" that Remington originally specified. The measurements I've taken on mine come out about 1-11.25". Contrary to popular notion, this is fast enough to shoot the current production 6mm Remington 100 grain CoreLoct factory ammunition (maybe the only 6mm Rem ammunition available?) very accurately.
My L579 HB is a superb long range varminter. I shoot a Nosler 70 grain Ballistic Tip or Varmageddon in it at between 3500 and 3600 fps.
I keep intending to take the L57 Standard out to hunt deer, but it has to wait its turn and there are still several nice Sakos ahead of it in line. (BTW: A good member here of the SCC traded the L57 Standard to a dealer friend of mine in on a beautiful L46 Hornet; in turn, I bought the L57 from the dealer. So, "B", thanks and I hope you're enjoying your Hornet and not missing your .244 too much!)
