i have been shooting the 300 winny for 15 yrs. now depending on your twist which my guess would be a 1 in 10 twist you should look for a 165gr. which hornady ammo should work thw best remember abount 4in. high at 100yrds. you willbe zeroed at 300. also remember shoot'em in the neck and they'll always be right there!!!!! good luck!null <BLOCKQUOTE><font size="1" face="Verdana, Helvetica, sans-serif">quote:</font><HR> <HR></BLOCKQUOTE>
