I was around an Uncle who was very big on the M99, when I was too young to appreciate what I was seeing and shooting. He had one in .243, .308, and .358. I shot the .243 enough to decide that it was "okay" (which was adolescent speak for "THAT'S really COOL! But I won't be cool if I act excited and thrilled about it."
It didn't take a lot of reading for me to figure out that I could hunt anything in the Western Hemisphere and all but a few things in Africa and elsewhere, with those 3 rifles, using the same cases and same or very similar powders! I had opportunity to shoot those three rifles over a couple of summers at my Uncle's place in Tennessee, and shoulda been THRILLED about getting to know them, but I was still in the "dumb kid" development stage.
I got back to Texas and told my shooting buddies about them, and how I thought they were the best inventions since Monday Night Football. One of my friend's Dad had a Winchester M88 in .284 which was HIS nominee for "Best Invention Since Monday Night Football". I shot about a box of ammo through it, and it struck me as A sorta compromise between the .,243 and .308, which certainly didn't suck!
HE knew someone with a BLR in .308, and I liked the time I spent with it.
All of those rifles have sorta ruined me for all the more "conventionally designed" lever guns made before and after them.
