New to the long range shooting world and do not hand load yet. The gun I will be using is an FN PBR Patrol 300 wsm with a 24 in barrel. Which out of the box ammo and grain would you recommend? I know that this is a trail and error type thing, but I do not have the $$ or time to buy a bunch of different ammo and figure out the best shooting. If you have never shot an FN 300 wsm, which brand and grain ammo would you start with or would be your first choice for a 300 wsm? Thanks
