Sure Bighole, take a Un-Primed case with a seated bullet, to your desired OAL. Drill the primer pocket out to 1/4", 5/16th may even be better. Fill the case with your powder of choice. Somehow, compact the powder. I use the back of a kitchen knife. With your finger over the new hole and the bullet pointed towards the floor, start taping. After about a dozen taps, you'll noticed the level of the powder has gone down. Repeat the process, until you can't get any more powder into the case and the new primer pocket is completely full. This amount represents a slightly compressed load. You can compress more, but it usually is not worth it. Now, this totally full case is the max amount for your OAL, weight it, anything under 80% of that amount is dangerous. The literature likes 80%, but I favor 90% or only a 10% reduction. However, that amount can be too much pressure for a starting load, in which case, another powder is in the offing. We got to do several things all at once. We've got to have enough pressure to function the action, a powder that is not to fast or to slow and at least 80% of capacity.
I just did a cursory google search on "Ballistic Detonation" and came up with this,
http://www3.interscience.wiley.com/jour ... 1&SRETRY=0There is allot to read and to be understood about this subject, but it is real and something I have seen many times. So, please, adjust a case and tell us the max amount of lil gun you can get into the case, with your bullet and OAL. If you have time, give us the numbers for 296 and any other, bullet-powder combinations you have time for.
Mudder, maybe we ought to have a Starting Loads Section, and or something good about Detonation, consider it..t
