I use the 120 and 140 Nosler balistic tip with great accuracy in my 15" Encore.
The SMK shoots extremely fine.
I have not used it on deer though.
The 168 SMK is the only bullet that will shoot 1/2MOA in my .308 Rem M700P so guess what I used for deer last year?
Believe it or not, my Encore 7-08 and the Nosler combo luvs WW748.
Range? I think the 7-08 and Nosler will kill deer and other big varmints cleanly as far as you can hit it good!
