Ruger,
I shoot a Browning BAR 7mm and shoot the Barnes XXX and have had great results from them.
My brothers and Dad shoot the Winchester E-tips and have had a lot of good results from them and shoot very accurate. Plus I was looking at the bullistics of the e-tips VS the Barnes and they are a little better I believe. Next time I need to buy a box I am going to try them out.
My Brother tried the Hornady Superformance GMX and could not pattern them worth anything and went back to the Winchester e-tips.
I do agree with you Ruger, since I have switched to the all copper bullets, they do devastating reults on whitetails and will never go back to lead.
