I haven't shot this brand, but I've loaded the 125 Ballistic Tips and got great accuracy. I also load these @ 2350 fps in reduced velocity .308 Win for younger shooters.
The bullets perform well at lower velocities. These should be worth a try.
I can't tell you personally about a deer, However I did shoot a Coyote this past Saturday with mine shooting the Remington 220gr. OTM. Ranged at 142 Yards, turned away, shot in the back of neck and bullet exited the chest area. It pretty much exploded. It was pretty nasty, by the looks of it I would say over kill for a deer. Im still gonna try it when I get the chance though.
