Hodgdon triple seven
We attempt to be on the cutting edge of everything new that hits the muzzleloader market that may have some value for our customers. We were excited about this new blackpowder replacement as we have been long time users of Pyrodex, another powder made by Hodgdon, and have always enjoyed excellent results. Rather than do any testing with the prototype powder released to writers, buyers etc. last fall, we decided to leave our testing until the powder was actually available to the public. We felt by doing this, we would be testing with the same stuff that our customers would be buying off the shelf and therefore our testing would have more validity.
ODOR: The first thing that you notice while using 777 is the lack of odor. By removing the sulfur, Hodgdon have totally eliminated all odor. This makes shooting and clean up a dream.VELOCITY: Hodgdon told me that with 777 their goal was to produce pellet velocities with loose powder. This would give the shooter the best of both worlds as they could easily "tweak" the powder charge and still maintain pellet velocities. Our table below shows that 777 has indeed accomplished their goal and some. In fact, some of the velocities recorded with 777 were the highest ever recorded by us with the barrel length in question.
