Im new to the site so a little about me, Im 20 ive been hunting aince I was 5, father was a LEO and trained sniper whole familys military. I have shot to 650 yards but that's it. I currently shoot a savage axis 30/06 with a bushnell doa 600 scope and a savage model 110e 30/06 with a bushnell doa 600. I have a H&R single shot chambered in 308 with a 16 power night stalker scope that I shoot regularly to 600 with . Im wanting to step it up a notch im looking between a 300 win mag, 338 win mag and a 7mm magnum. I just cant choose and have never had any experience with them. Any input would be helpful.
