I am loading some rounds for my son Brandon's 270 Winchester. Has anyone used the Sierra Gameking bullet in 150 grain? I am looking for a good bullet for Bear hunting for him. I have a 7 mm WSM with 180 gr. VLD berger, but he is left eye dominant and loves his LH Tika T3 and wants to use that gun. I loaded some up today and we will see how they shoot for him. If you have any info or a favorite bullet for tough game like a shoulder shot on a big bear we would appreciate any guidance.
