CIL was known in Canada for providing relatively affordable and good ammunition. In European metric calibers CIL provided generally stiffer loads than was available from the American manufacturers. My only experience shooting CIL 6.5 M-S loads was in the late 80's or early 90's hunting Blacktail Deer on an island off the west coast of Canada. With a nice M-S 1903 fullstock carbine I missed a very easy offhand shot at a Blacktail standing broadside at less than 50 yards.(I switched to some other brand of ammo and shot a deer later that same day.) Back home at a rifle range I found that some of the CIL bullets (not all) were tumbling out and hitting the paper sideways nowhere near the point of aim. They were ancient and I should not have taken them hunting. I don't know when CIL stopped making ammo, but it seems like a long time ago now.
