i have been visiting this sight for quite a while now and was in the process of building my first long range hunting rifle . wanted to know if i was going in the right direction or not. the gun i want to build is a 7wsm. that would be mainly used on deer but may also see an elk or two. i was going to build it on a savage action . my one question would be can i purchase a regular long action 7mm and use it as a 7wsm? would also like to know what size of leads to shoot out of it. any input is welcome. thank you.
