well, $30 a bag - that's not quite double original price

lots of stuff is worse

I just bought them on the Precisionreloading.com site for $20 per bag.

You could check BPI. I've used their 10ga wads in the past using the same data I had been using. Or order some circlefly fiber wads.

Yes, the BP 1044 wad is the closest to the Rem SP10 and should be able to be used as a substitute. I loaded 10 shells with them and they will work with my recipe.
