It scored my damascus barrel in a old gun, I used a fibre wad , with the inverted card cup system , soon kicked that into touch . Needs a wrap to protect your barrel like you would always with itm.

There is likely to be score damage to bores when using totally enclosed card cups in short cartridges through long chambers too! The card cups can break up when entering the forcing cone, allowing the shot to come into contact with the bore during the breaching of the gap between the case mouth and the barrel proper!..........Had it in a 4 1/4" chambered 8 bore when using......3 1/4" cartridges! Tungsten based ( ITM/ITX etc) shot will score the bores, if it comes into contact with them!

thats what i have always thought, and had great debate about. how soft is soft enough to use in specialised shotguns. when i did my testing of itx10, it was with the tubo24, gualandi wad. it fits about 30grams of itx10. a fantastic catrtidge actually that slightly performs better than comparable 32g niceshot and bismuth. with this itx 10 stuff i would easily try and load +2 shotsizes, compared to lead.
nb, model used 1400fps loads.

It all depends on the ITX: Itx10 is fine to load with regular wads no probs. When I checked that with BPI they said they had successfully load it with gualandi and b&p wads. The Issue I found with fiber is that it doesn't pattern well at the speed required (BPI suggested 1350-1450fps) for most foreshore shooting. Most likely due to the gases escaping and causing pellets to move astray and some deformation in the pellets when in contact with the barrel (some pellets unrecovered were flattened in on side). I think a mylar wrap could reduce deformation  and potentially a gas seal eradicate the issue with gases. Slower  loads pattern well but when I submitted the data the BPI technician advised to shot these over decoys for best result. ITX13 is a completely different pair of hands and it does require steel rated wads.

good post, there is a world of difference between itx10 and itx13 or extreme 13

if i was to design and build a load now, i`d try and find lead loads using the fsc- fibre shotcups.

Yeah, that's what I've done based on your volumetric tests. It works great with ITX10, the only thing is I'd probably increase the powder by 0.05 and drop 0.5g from the it's volume. That'll ensure a good doped with good stopping power. For decoys/pond shooting even just the increase in powder will give you a good shell
