Just my opinion, but i feel the same way about the BLR, but any of the three would sure work. I own a couple of savage 99s and a blr, and did own a win model 88, until a friend talked me out of it. All of them are very good platforms, but i have two reasons to prefer the BLR. Firstly, the rotating bolt, is so smooth, it is a delight to crank. Secondly, it has the best factory trigger, smooth and relatively light, but with a shade of overtravel. I did really like my model 88, liked working with it, but its trigger was.....well.......below average. The model 88's trigger in all fairness was better than the only 308 savage 99 i have fired, a very handsome 99C, whose trigger felt like turning the key on a sardine can. I expect things that like vary from rifle to rifle.
Anyway, if he wants a lever in 308 he has three very good choices, and either way he goes he will be tickled. What a good problem to have, having to choose one of those fine weapons.
Take care,
Steve
