A few years ago, we came across a mattress ticking at a local sewing shop. This material, 100% cotton we called mattress ticking, a very tightly woven cloth that turned out
to be a SUPER patch material for ALL of us up here. Compressed in dial calipers as tightly as I can squeeze the tines between forefinger and thumb, after washing it measures (just re-did it)
.023". I've even used this material in my .32, with .320" balls and in my .40, with .400" balls, being dead soft lead, of course (from X-Ray Room wall lead sheeting). It also shot well
in the .58 Kodiak with .562" balls as well as .574" balls. Taylor's A. Verner .50 with .495" balls, my .50 Beck (by him) with .495" balls, my old .45 with .445" balls and the .69, with .682" balls.
It was even "perfect' in the 20 bore (choked) with .595" balls.
Alas, we can find no more. I still have a few scraps.
Red, White, Light Blue and Dark Blue stripes.
If I could find a bolt of this stuff in Canada, I would buy at least 1/2 of it.
