I tested Viht 310, Red Dot, Clays, and Titegroup. 4" barrel with 200gr XTPs.
Red Dot 5gr: Cleanest, made this one of my standard powders. FPS 800-850.
Clays 5gr: Cleanliness comparable to Red Dot, low FPS 730-760.
Viht 310, 4gr: Little dirtier than Red Dot, FPS 850-900.
Titegroup 5gr: Dirty stuff, FPS 850-880
COMMENTS:
Viht N310: I would like to shoot this powder, but I bought this pound a Perry for $16. Don't know if I will have a steady supply or cost to make it one of the standard powders.
Titegroup: I will finish off what I have left, but fire no more than 100 through per session.
Clays: I have a free endless supply of this powder. Get it from a trap shooter (my Dad) that will keep this powder on my bench.
Red Dot: Good stuff!
