roomy hull

[Paul Harm]

First off, a Remington hull is tapered wall hull[ Win also ] where as the Cheddite is a straight walled hull. That's why the powder is leaking by. Many recipes show a wad for a tapered hull used in a straight walled hull, but you see the problem with that clear hull. Even Claybusters shows their Win/Rem wads being used in straight walled hulls and they make a wad for straight walled hulls. Don't ask me why they list them. Any hull except the Rem/Win is straight walled. To the best of my knowledge the 10ga, 16ga, 20ga, 28ga, and 410 are all straight. The only exception is the Win AAHS hulls. They take a special wad. Second, the RP12 wad is meant for 1 1/2oz of lead shot in a tapered wall hull. Go to BPI and ask what wad to use for a bismuth load. It's different than a lead shot wad. Make sure you mention if they don't ask what hull you're using.

Paul’s comment reminds me of an embarrassing blooper I had while shooting at Wallingford with Dave Suponski. I had loaded up a bunch of cheap Winchester hulls with AA wads,but the hulls turned out to be straight walled. I took my station, confident I was going to nail it, and after a mere pop, burning powder shot out the front along with wad and shot, which landed about 10 feet in front of me. We made quick work of the grass fire, and while the laugh was on me, I couldn’t help but laugh also.
