mdrbowler,

The reason most guys use 100 grain is because of accuracy. At 150 grains my gun kicks a lot more and there is more "inconsistancy" with grouping.

If you have consistant accurate groups with 150 and don't mind the recoil then stick with it.

You also need to know that triple seven is what most of us use and It burns approx. 20% hotter than Pyrodex. 100 grains of tripe 7 is like a 120 grain load of pyrodex.

Check out this web site and look at the velocity comparison chart:
