In reviewing this thread, I don't see anything about Warne rings. No longer made but frequently found on eBay, Gunbroker, etc., these clamp directly to the Sako dovetails and were available in fixed or QD versions. I have found them to be ideal for the long action Sakos. The mounts index on the front and rear of the ejection port, allowing more flexibility in mounting than a regular Sako ring. I do not think there would be a problem with .375 recoil - Warne knows what they are doing. Here's a photo of my .30-06 AIII carbine with a 1.75-6x Leupold VXIII in Warne QD rings. The slight overhang of the rings over the ejection port is due to the indexing tabs.
