I am new to LR hunting and shooting. I have a Rem 700 sps with factory barrel in 25-06. I have installed a B&C medalist stock on the rifle and a Timney trigger. Is it possible to shoot this set up , with a good hand loaded 115 Berger ,out to 800yrds ? Can I expect any consistency with the factory barrel out this far ? I mainly just want to ring steel with it.
