Winchester gxp2 have used the power pt. also the win gxp2 silvertip.
both 150gr. my 06 likes them a lot. does ok with the remington stuff
but i guess winchester like's winchester
I hunt blacktail and so far none have run off when hit with winchester ammo
did have to put another round in one once with reminton tho
MHO try the slivertip's on muleys, or go up to the win supreme gxp3. 165gr nosler. plan to use them on Elk
