I used them aswell in my .308 with 180 gr.
I've been using those to hunt deer for... (thinking)... about 10 years now and the deer dont seem to know the difference... if there is any.
I'll be trying them out in 2 weeks for bear so I'll let you know what M. Bear thinks.
edit: WOOO WEEE! you earned my first post on this forum! I am now a nice and yummy fawn!
