I have two interarms Mark X rifles that I bought in the late '70s. One in .22-250 and the other is a .257 Ackley. Both have served me very well. I have probably killed more North American big game animals with the .257 AI than all of my other rifles put together. Everything from varmints to deer, antelope, bighorn and dall sheep, to elk. I've had a 6x Leupold on it since day one.

You also asked about the Rem 700 ADL. My first 7 mm Rem mag was a 700 ADL that I found in a pawn shop. It came with a 3-9x Weaver. It worked fine for me on my first South African plains game hunt and a Muskox and caribou hunt in the Canadian arctic.

I traded it (at the pawn shop) for another 7 mm RM in a Rem 700 BDL because the BDL was stainless steel, I like the floorplate, and the BDL barrel was clean without iron sights. I've also used this rifle in Africa and for antelope and elk in Montana. I recently put a Nikon 4-12x Prostaff scope with their BDC reticle on it.
