[QUOTE="EastTNHunter, post: 4980430, member: 8364"] You’re missing a few parts of the equation if you are comparing to a cartridge load. A ML starts with the bucket seated tight in the barrel and against the powder. If you don’t do this then you can risk bulging the barrel with even acceptable loads. With a cartridge load you have space inside of the brass case, as well as the leade for the bullet to jump. This allows for some expansion room and allows for some pressure to build more slowly and avoid the spike. This makes a huge difference, not to mention the trap door loads for 45/70 use a very reduced powder charge which created a lot of expansion room in the casing before the bullet jumps the leade and contacts the lands. This phenomenon can be seen to some extent by working up a load that has too long of an OAL and getting a big pressure spike. This is why you can’t compare those apples and oranges [/QUOTE]
