I may someday get a smokeless, but quite honestly at this point I don't want one due to the fact I'm prone to being a bit thoughtless. It's a real possibility that I would load it with 90 grains or smokeless by volume and blow it and me to pieces!
That could be a problem but then again the barrels on the smokeless have been proof tested to excess of 125,000 psi. Depending on the powder you more than likely get a nice half moon cut on your eyebrow that will need stitches.
When Mike shot his smokeless this week with an aluminum ramrod and a brass spin jag on top of his load he should be happy he was shooting a smokeless MZ. Results could have been much different with a lower pressure rated barrel.
MZ's do not leave much room for operator error and it is SO easy to make a mistake or to not really understand the cautions you need to take to stay safe. A bullet moving off of the powder charge, or not fully seating the bullet is one of the main culprits in barrel failure. It acts like a barrel obstruction. Pyrodex, T7 and others do not need compression from the bullet to ignite. With smokeless if it is not compressed it will not ignite. This is another reason why all should be careful and ALWAYS check your bullet seating periodically while hunting, especially with easy loading bullets like powerbelts. If the go down the barrel easy they can move off of the load easy also. I have had guys tell me they had them peaking out of the end of the barrel after a day of walking and hunting.
Check everything and then check it one more time BEFORE you pull the trigger.
