Hello, I am new to the forum and kind of new to the older Sakos. There is a little bit of contradicting info out there on the internet on rings. I purchased a M579 .243 and few years ago from a old friend that was selling it, since he never used it any more. It's name is Moose Killer, because he used it for that and to take down elk. I have a picture from the 70's of a small paddle moose he shoot around here (1 shot in the neck on the run) and loaded it on the back of a VW Beetle to bring out of the mountains. Chuck was/sometime still is a most excellent shot. One day playing at the range, I decided to see how it grouped at 200 yards and lo' & behold it was still same holing the A-max like it does at a 100. To see this rifle one would not think it capable of such; cut-off stock(Chuck does not like much LOP), old extended Weaver mounts, a 1961 Redfield scope, and kind of used looking. I guess I am kind of hooked on old Sakos now. Spent a few years looking and found, at a gun show, a 7mm Rem. Mag. Finnbear L61R in great shape with a very heavy barrel (original)(told its a 1980s, long range and a little rare). I am starting setting everything up; new scope, rings, dies, components for it. It seems hard to find a good set of solid rings for this Finnbear and I read about rings being out of center-of-boar, then a lot of the used ones available look wimp and the people selling them are getting rid of them due to problems (eBay). Probably, as monies are saved up, I am going to put a Zeiss Z-1000 on it. Even talked to a guy that wire cut a couple sets for himself because of the problems he was having. Looking to what is available for sale and it looks to mostly be for the newer Sakos. I have emailed Leupold(Matt Chin) and they told me they only have 11mm rimfire rings mounts that will work; that does not sound good. Yet, on this forum there are mentions of Leupold rings mounts. Contacted Warne and they told me Sako would not give them correct specs. How good are the used original Sakos? Anyone using the Leupolds? What are you all using? What is good? What is available?
