Note: plaswads are somewhat difficult to measure exactly. Please take the dimensions as "pretty close" only...

1 - Distance from the bottom of the overpowder (OP) cup to the bottom of the shot cup. Note that the REX is an
unusual wad in that it has a concave shot cup bottom and the OP cup is quite deep. In the 410 section, I have added the shot cup petal thickness as this may affect volume.

2 - Measurements of the new, stiffer, Winchester AA 12L. It's also now 1 mm shorter and a grain lighter.

3 -  CB0178-12, Winchester 12L replacement. Noticibly softer shooting 24 gram wad with very smooth recoil.

4 - Helarco(US) VP 05 has an unusually deep, squared off (not hemispheric) OP cup, 5.5mm deep. Wad can be easily used for 1 oz/28 gram shells as well, especially when using dense powders.

5 - Re: Gualandi V0/SRC. The wad referred to is the one with teeth in the OP cup. Ballistic Products calls this the
Short Range Crusher.

6 - Tho Claybuster calls this a 1 oz wad, it fits well in Fiocchi 6-fold cases for 24 grams. A little 24 gram loading data would be nice here. 

7 - The CB 1034-20 has a truncated cone located in the the center of the shot cup, about 8 mm wide and 4 mm tall. See picture at the page bottom. Note: production wad will be re-numbered to CB1075-20 and the wad color will be green to eliminate confusion with the CB1034-28 wad.

8 - Downrange PC410R wad has a powder anti-migration ring.

Generally, a 24 gram wad will have about 27mm length. Wads intended by the manufacturer for 28 grams are useable for 24 gram loads by choosing some of the following: bulkier powders as Red Dot or Clays, shorter cases, cases that have smaller internal dimensions, 6-fold crimps and by lowering the pre-fold die to take up more plastic, effectively making the case shorter.

There are many recipes in the propellent manufacturer's reloading manuals using 28 gram/ 1 ounce wads to safely load 24 gram shells. The manufacturers are very responsive and helpful to any questions that arise.

Euro wads from Bacheri &Pellegri and Gualandi are available at ballisticproducts.com and precisionreloading.com. HelarcoUS wads are available from ballisticproducts.com.
