So I acquired a new T3 in 300wsm for $300 and want to make this a dedicated mule deer/elk gun. I was thinking of using a factory load in 165-185g for both. I would like to shoot this gun out to 600-700yards. Any recommendations on what I should feed through this? I shot it this past weekend at 200 with Federal Berger Hybrid hunters with a cheap scope and it shot good but thats the only option I had when I bought ammo at the time for it as well.
