My first rifle was a Remington 722 in .244. I got it when the fellah that had it read how inadequate it was on deer, without a 100 grain bullet. Remington, in those olden days, loaded a 90 CoreLokt that was the best bullet I ever used in that diameter. Of course, the gun writers didn't tell you that the .243's 100 grain bullet passed right through deer with hardly any expansion, back then. Speer made a 105 grain round nose the .244'd stabilize, but I didn't like them, they didn't expand or penetrate as well as the CoreLokt 90. I never did understand that. Unfortunately, Remington dropped the bullet when they changed the name to 6mm. Now the closest you can get is the 87-grain Hornady. I had a 6mm in a model 788 after I lost the use of my right eye, gave up on it, as I couldn't do anything with it that couldn't be done with my Savage .243.
