I found a post about Hawk bullets(http://www.hawkbullets.com), has anyone used them, their a custom maker in Canada. They use annealed copper tube around round nose or points and claim around 80 to 90% weight retention, deep penetration and useualy an exit hole. The bullet weights seem in some cases to go higher than other brands, 270 win, my choice, don't knock it, goes upto 180 gns. Ive read about importing heads from the states and was going to get some Barnes till I read about them penciling in another post. This website has so much imfo for us, theres a huge pool of knowledge out there for us to share. So 270 win, plainsgame what weights, any loads with Hodsgon H4831 sc. My 7 x 57 was ok, but I have a mannlicher proffesional M, I use it every week, best to take a familier rifle. Need heavy bullets though, will find out twist rate, deerwarden.
