Over powder wads

[J. A. EARLY]

The HEVI-SHOT company uses flax seed as a filler, so everything stays in the shot cup and the seed is placed on top. This would allow you to use the SP10 wad and keep the shot inside and adjust the amount of filler you need for each shell. Flax seed is cheap, less than $5 for two pounds.

Plus you can eat it while reloading and have a healthy heart!

Putting a filler wad on top of the shot has the opposite effect the OP is trying to achieve as it creates a spreader load. I don't know if Flax seed would have the same effect but I would put it on the pattern paper.

The best ways to tighten a pattern are; larger shot, slower velocity, harder shot (maybe try copper coated), and granulated buffer.

Perhaps you could try a mylar wrap and see what that does.

Thanks for all the advice! I think I will try shortening some shells...maybe be some Blue dot loads which use a lot more powder. The harder shot and mylar wrap are worth some experimentation too. Sure is fun experimenting with these short tens....

I don't think HEVI-SHOT would use it if it caused the pattern to spread. They use it in all of their Hevi-metal and Hevi-steel loads, and I get great patterns out of full chokes using the Hevi-metal shells. I personally believe that if the shot is all contained within the shot cup, the pattern cannot be affected by something as flimsy as flax seed which will be blow away by the shot coming out. I believe it will disintegrate immediately. I've shot hundreds of rounds of it. I feel confident it has been proven by them.

Take a look at their cutaway drawing.

Thanks for sharing. I'm always learning something new on this board.
