[QUOTE="Trickymissfit, post: 722296, member: 25383"] I did this with a mechanical CAD program that had 60K psi factored into it with a standard 30-06 bolt face with 60K psi pressure. Results were most interesting. I did it wiith generic 4350 pretreat steel that had a hardness of 30RC. I simply took a short actioned .223 and made measurments off it. (scaled them up. The bridge shifted all over the place on the round Remington action as well as the flat bottomed Mod. 70 action. The area behind the bolt seating area was much stiffer in the Winchester style due to the squared surfaces of the flat bottomed reciever. But the tops on both action needed work. Even more interesting was what the barrel did during the travel of the bullet. Seemed to twist in two directions at the sametime, but the slower the twist the less it did. gary [/QUOTE]
