I recently purchased a Tikka t3 light chambered for 300 win mag. So far I have been able to shoot 1inch groups. Does anyone have a good whitetail load that I should try. This rifle is intended for whitetail out to 600a yards if I can get the accuracy im looking for. The load I have gotten the best results with is a 150 gr nbt over 71.5 grs of IMR 4350 and a fed 215 primer. Any help would be appreciated. Thanks.
