If that were true any 50 caliber barrel, no matter the length, with a 200 grain powder charge in it would turn the bullet into an obstruction, correct? Second part of my question, if 200 grains of powder will not ignite at once and causes the bullet to become an obstruction, will the same phenomenon happen with 175 grains of powder? Or with 150 grains? And before you answer, remember, there are number manufacturers out there selling guns in 50 caliber ‘rated’ for 150 grain powder loads, with a few even higher (not saying that is a good idea). I wonder why they don’t all blow up from the bullet obstructing the bore as the black powder doesn’t ignite all at once?
