A few years back BASC in the UK commissioned lethality study on game cartridges, part of which was a measurement of pattern percentage variations between fibre and monowad cartridges.
In cartridges loaded as nearly the same as can be there was no discernible difference in pattern percentages. Both sets had modern star crimps in plastic cases without a card overwad.
Twicebarrel If you'd like a copy of the study just drop me your email addy to MOLLOP@AOL.com. I
think I've got it stored on my No.2 PC.

PS as an afterthought ... the only spreader loads I've seen that actually worked had a cruciform insert running lengthways in the shot charge. You might be able to buy them in the US. Alternatively you could spend the evenings cutting bits of cardboard into to shape and glueing them together.
