Just got my reloading kit and got a Speer reloading manual too. Got to looking at the Grand Slam bullet for the .308 and it looks like they make it in 150gr. and 180gr., anyone have any advice on either of these bullets for whitetail within 200 yards? I' ll be using Win. 748 powder and CCI 250 primers starting out at the low end of the powder suggestions and work up from there. Thanks! CAN' T WAIT TO GET STARTED!!!
