sounds like you should start to reload. You have many options available to you as a reloader, so you can change the bullet type for the performance you are looking for.
I switch the .243, .270WSM, .300WSM to meet the needs of what I am trying to achieve. If just shooting paper, I shoot a cheaper bullet and use a lighter load. If I want to prepare for hunting, then I work out my hunting load for power, accuracy and consistancy. If I want to have a little competative shooting, then I go for a good bullet ( usually a FMJ match in the .300) and go from there... the oportunities seem endless.
suppose my .243 was my favorite rifle, and I wanted to shoot a deer.. i would use a different bullet ( heavier) than I would for a coyote. I may also want to change the terminal ballistic performance of the bullet ( what it does when it hits the animal), so I may use a sierra Blitz King for ground hogs, where I wouldnt use this bullet on a deer.
Keep in mind though, when you switch your bullet wieght, sight in again before heading out... you might miss your target!
