Hello Dave,
We are discussing two different activities here. but do have some things in common.
We both shoot obsolete firearms, dress in proper period clothing ,and compete against others for accuracy and time.
Other than that it is a completely different competition.
SASS requires very fast and still accurate up close. For example ten rifle, ten revolver and four shotgun requires a competitive time of under 20 seconds hitting targets in usually six different stages with different sequences.
That is what I meant by running the guns.
N-SSA requires accuracy at a distance but still against the clock or other contestants or teams.
Again both demand reliable guns and ammunition.
Both are fun, I enjoy watching videos of N-SSA events.
I enjoyed shooting SASS I can't say very competitively but I had FUN just like you.
Let's burn some Gun powder and both have fun.
respectfully
Bunk.
