Ever clock your shotgun?

I just clocked my shotgun 12ga 1 1/4oz - 2F square load. Highest velocity no matter the wad column was 1086fps. Just curious if others get more/less with theirs?

Couple things important about m/l shotguns.... Use equal amounts of powder to shot by volume. Use one size shot larger than you use in modern cartridge shotgun applications. To prevent blown patterns caused by too tall of a wad column , use only two .125 card wads on top of powder. The .125's decelerate quickly and the shot is not scattered. Also , on top of the shot ,use 1/2 of .125 wad to hold shot in place. Works for me..

Looking at the black powder hand book they show velocities in the 11-1200 FPS range but no info on how it patterned

Less powder more lead, kills birds dead. More powder less lead, wider spread.

Equal volumes is the square load I mentioned in the post, My patterns are about as perfect as I could hope for. Better then my 11-87. The question was one of speed. I'd like to get 1150 out of it maybe.

Does a difference of 130fps really matter though?

Perhaps not, but with the other poster quoting "book" velocities so much higher and my own reading of other materials that confirm what was stated, I have to question my methods. The brain trust here is fantastic and I was hoping to tap in to see what was possible.

Well, that's almost 89 miles per hour.
Muzzle velocity is one thing, but it's target velocity that matters.

Shot slows pretty quick, and straight bores open up quickly. Something that counts at forty yards might not matter for you at twenty five. Turkeys thumper and tree rats seem to go down pretty quick in range.

130 FPS could mean the difference between a 20 yard kill and a 25 yard kill.
something to consider.
