I just started working loads up for some 180gr Missouri bullet company TCFB. The gun i plan to use them in is a XD40-V10. When target shooting with WWB, I usually have to clean the front sight post every 200-300 rounds because of the residue buildup out of the ports. With the lead, it is completely covered by the 5th shot. I have been told this is from the bullet lube. Is this normal? Would a different company's bullet lube burn cleaner or are they all the same? Does anyone have any experience shooting lead through a ported barrel?
