New to LRH and I do not reload my own so my question is what is the best OTC ammo? I use a TC 243 for Black tail deer, prong horn and a Rem Mod 700 270wsm for Mully and WT deer and elk and a 35 year old Win Mod 670 30-06 for elk and larger. I feel I have good optics on all three guns Nikon Monarch. Any ideas on ammo???
