re: ideal 300 magnum

Hard to beat the win mag. Plenty of velocity to push up to 215 grains. I had one built with the throat longer than a saami throat and it pushes berger 215 hybrids about 2800 fps. Shoot it as far as you want, and don't have to worry about changing the barrel every 800 shots. Which ever caliber you choose call ptg to make you a custom tactical or competition reamer. It's a few hundred extra but well worth it. That way when you do have to replace the barrel the chamber will be exactly the same.
