what would you consider adequate time between rounds to where i wouldn't be "hammering" them through the pipe. </div></div>
It really depends on the outside air temp along with several other things but, for range work with magnums I limit myself to three shot groups and let the barrel cool between each three shot group. Since the RUM use's a slower burning powder like H1000, Retumbo and or RL-25 it may take 3-5 shots, one after the other, for the barrel to heat up to a point that it's hot to very hot to the touch. You just have to check it as you go and stop when it gets hot. The accuracy wont suffer like a factory barrel though but, when it's hot and you keep hammering shots through it, thats when your wearing the throat out faster than normal. Remember, heat is the enemy when discussing barrel wear.
