Sako 85 - have had a good look at - nice rifle and I do like the controlled round feed, and I think it has a better stock shape than the 75. Sako also build their actions so that they are a true fit for the cartridge.
Don't like the safety, with seperate fiddly little button to press to open the bolt with it on safe.
But would suspect that it will shoot very well - certainly any Sako I have used has done so.
Heym's are in a class above Sako's and are more akin to a custom built rifle than mass produced weapon which the Sako is - albeit the Sako is very much the best of the mass produced factory rifles IMHO.
Some of the Heym's do have a very germanic style stock which you either like or don't. Mine has staright classic style which I prefer.
Calibre - 7x57 - very good all rounder. .223 havn't used albeit its baby brother the .222 is very sweet little calibre.
Have fun with one either or both.
Heym SR20.
