looking to find options for rebarreling my R700SA in 300wsm. wondering what options are available. looking for long range shooting. wondering recommended twist rates ect and barrels available. also wondering about muzzel breaks with downward pressure to counteract muzzle rise for faster target acquisition. thanks

Remington Model 700 Short Action barrels can be found here...in a variety of calibers, twist rates, and muzzle breaks:
