I bought a box of Great Plains Bullets today and the factory lube they put on them is not there. There is no residue of lube in the box what so ever and the bullets are bare lead. The last box I bought the sides of the bullets were almost solid white with lube. The box says they should be lubed. Will this make a big difference in accuracy with them not being lubed? The only thing I have to lube them is bore butter. Should I put some of that on them?
