I will bet ya the nipples are worn out!! Replace them with slixshots for $36 and your works will amazingly shrink in half! Be careful removing the old one is this the case, once your strip the useless hex on them you are in for a ride. If you have to, soak them in Kroil overnight and heat them up with a torch before trying to removed them, play it safe! Ask me how I know. I have 5 ROAs and all of them have fitted extra cylinders, all seem to shoot good with 28-30 grains of 3F, ball and lube ( whatever that pleases you, even Crisco) and good I mean 2 in at 25 metres. Kaidos are good, but the Lee mould for their 220 round nose for the ROA is more useful for hunting loaded normal and upside to make a nice wadcutter, shoots equally accurate loaded either way! Try all the rest of fillers, wads, cardboard and such but in the end it will make little difference but it will be fun to find out for yourself! Enjoy it while you can! Welcome to the forum, BTW!
