[QUOTE="AKSavage, post: 1391757, member: 95938"] Yes you are right. I was making a mistake. The number I was reading on the reamer print was not to the bolt face, so it would NOT be the OAL of the cartridge. Good catch. It's to some datum line IN FRONT of the bolt face, on both reamer prints. The top of the belt, maybe? It does not say how far in front of the bolt face this datum line is though, although almost all the other measurements are referenced off this line. The problem is that neither reamer print shows HOW FAR from the bolt face this reference line is, or it would be a simple matter to add this in to get the OAL, and hence subtract the same amount from the .295 throat length. Time for some more calculating and head scratching. Maybe someone more versed in reamer prints can chime in. Both reamer prints I'm looking at are from PT&G, and in both cases the numbers/measurements (2.534 and 2.699) are the closest to the edge of the paper. [/QUOTE]
