[QUOTE="DavidA, post: 2834006, member: 72334"] That is a problem. Not knowing what pressure signs look like at 80,000 psi. The bolts would Handel it, but only using dimensional comparisons could be misleading depending on the difference in alloys used. But boltvsaftey sheets are probably set a 5.5 times failure. But 80,000 psi load’s would accelerate throat erosion crazy fast. Again it might require using a Speacial metal alloy insert or coating process for the first 2” of the bore. Otherwise your barrels would need to be changed as much as your underwear. It can be done and done safely, but you need to do s lot of testing to figure out just what needs to be done. Then just like the hybrid case you develop a hybrid barrel manufacturing process . If you do testing yourself , you are going to need a lot of equipment and know how. Like with a stress gauge on different parts of the rifle to see just what need to be done. So slapping a new barrel and hoping for the best may not be practical, or safe. It’s always desirable to be on the leading edge, just don’t want to be on the bleeding edge [/QUOTE]
