0.678" is a good fit in some shotcups and just a bit loose in my Winchester 1 1/8 oz. yellow wads. One wrap of paper or cross patches fixes that but is a bit of a pain.
0.662" RB's are loose in regular shotcups but cloth patching fixes that and they are a PERFECT fit in CSD steel shot wads. Greg Sappington had told me they worked well and he said he had an article about a guy shooting them in fully rifled barrel as an "attached wad" slug with good results. I hadn't realized Greg sent me a few of those wads so I checked and they are a perfect fit in my bore with 0.662" RB pressed in with shotcup cut down and two 16 ga. nitro card wads under the ball. I will be trying those out shortly.
Even if they don't work as an attached wad slug, the slit version of the wad will make for easy loading with no patching. I'll have to order in though and no local supply here.
good luck in your loading and keep us posted on results.
