Ray, you could very well be as right as rain, I have nothing other than opinion,myself, not being educated in advanced physics, and my sources are exactly the same as yours, almost a life time of hunting with rifles, of all types, and handloading for 50 years, along with 46 years of owning,useing, and loading for double rifles! I certainly have never damaged a double rifle with mono-metel bullets, because I only used them one time, and had to take the rifle appart, and use dryice to shrink the steel, and brass to get the cases out of the chambers, because of the over pressure. The rifle turned out to be OK, however, I didn't shoot any more monos in a double. That was my fault, because I used the same load that regulated with softpoints, and fire both barrels before trying to break the rifle open. I screwed up, because I did not reduce the load, and work up! I'm still open to the use of Monolithic solids in double rifles, if some one can show me one that will work without damageing my rifles!

The North Fork looks like the answer to me,with the grouves to relieve the pressure needed to engrave the rifleing into the bullet,without haveing to compress the whole bullet! Now, if we could just get him to make some solids! Nitro 450 #2, and I talked to him for quite a while, at the DSC show, and his bullets really look nice to me! His velocity/upset displays are impressive, to say the least!
