...These loads REQUIRE a dacron wad(about 1 grain) to keep the powder in position...
Please note that the above is
obsolete information and is one reason it is wise not to use old data. Lyman
no longer recommends, nor do they list, any loads with fillers. Too many problems, risks of barrel ringing, and the fillers are not needed anyway. The #48 Manual lists a few .45-70 loads with Unique, all without fillers of any kind.
I use both Unique and BlueDot in my T/C .45-70 and accuracy is great without fillers, expecially with BD. I get better accuracy with Unique by tipping up the muzzle prior to the shot, BD seems less position-sensitive. I use standard primers only.
