This is just to help me make up my mind. I have never been a fan of the short mag FAD but I got bit by the bug the other day. Im going to have a short magnum built but Im just torn btween the 7mm WSM or the 300 WSM. The gun will be used for deer hunting, and my long shots are no more than 500-600 yds, most along the lines of 100-300yds. I was just wandering what the pros and cons of both cartridges are. I want to shoot any where from 168 to 185 gr bergers and i want to know if the 7WSM has the UMPH to make it a future long range rifle. Ive always like 30 caliber but would like for my little girl to be able to shoot the rifle some day so a muzzle break is already in my thaught process for that. Would the 7WSM be more suited to a smaller frame shooter, I shouldnt say she will be small framed. Im 6'2 270 and work out 3 to 5 days a week, and her mom is 5'9 ex sports guru in high school, so my little girl wont be so little when she starts shooting this gun. What weight bullets would work the best in either and what are the best powder choices for the short mags. Sorry for the long read but I am totally new to the short mag stuff.
