Im new to long range hunting and this site. there seems to be alot of experience and a wealth of knowledge here. Im interested in the Berger VLD hunting bullets. I have a Rem. 700 SPS Tactical .308 with 20 in barrel 1:12 twist. Im capable of .75 in groups with my 'ol reliable' win supreme 168gr at 100 yrds. What would you recommend for me in the VLD. my longest shot will be 500 yrds. Please Help!
