That is going to be a LOT of stress placed a sheet metal reciver and rivets. I am talking recoil here not chamber pressure. looking at the balistics this thing is hotter than a 375 H&H by 300 fps. so one can only assume it is loaded to the max pressure wise. it is a good deal longer than a 30-06 as well. If you are in russia and can find parts I would try to get a hold of any 3 lug trunions and bolts you can get if it is legal. I am not sure this is a build you want to do on a AK system?? I guess the first step is to get the chamber pressure and then do the math calculating in the huge 1/2" base to get the bolt thrust. the 1/2" base is going to increase the bolt pressure over a simular pressure round with a smaller base. this is an awsome round for shooting big stuff 270 grain bullet at over 2800 fps is. that is almost as fast as a 30-06 sends a 150 GR out of the pipe. I show loads for the 06 up to around 5900 PSI this being a MAX load. If you want this kind of power why not go with a more common round like the 375 remington ultra mag? If you were to hand load and absolutly must have this round in a AK I would strongly urge you use some type of reduced loads to keep the champer pressure in the 30-06 bolt thrust ball park.
