With my new heavy barrel after 8 rounds of 100gr Balistic Tip with 65gr H4831 you can still grab the barrel and not get burned. The original Remington barrel after 5 rounds of 100gr HP with 70gr H4831 would give a bad burn if you grabed it. It lasted from 1963 until 2009 and I tryed not to shoot more than 5 rounds without a cool down. My new barrel is a 30" Shilen with a taper starting at 1 1/4" dia to 3/4" dia at the muzzle it has 1 in 8 twist, hand lapped stainles steel, bead blasted with a 11 degree crown. The action and chamber are glass bedded to support the weight and the rest of the barrel is free floating. Recoil is very mild. My belief is if you want to rapid fire get a AR platform which I am considering in 338 federal which has impressive baslistics and energy for a short round.
