I've been using, off & on, Lee TL bullets .39 Cal 148 WC/158 SWC .41 Cal 210 SWC, .44 Cal 240 SWC, .45 ACP 230 RN. In the Mag calibers I keep load to about 1,100 FPS. I used to use XLOX alone . I found that I'd get some leading and that the gunk would quickly accumulate on the seating stem; with each subsequent seated bullet, they'd be driven deeper into the case. They were every bit as accurate as any "regular" cast bullet. I then tried a new technique. I would TL the bullets with the XLOX. Then do another TL with a dab of some Liquid Car Wax...just enough to cover the bullets. I did not coat the bullets "too heavy" with the XLOX. I would then place the TL bullets in a shallow pad and let them sit for a few days to "dry". That stopped the seating stem issue and I found that the (minor) leading issue was greatly reduced. I do know that one can buy/make 45-45-10/Deluxe XLOX. However I bought 32 ounces of XLOX. 32 ounces lasts a very long time. Can anyone share their thoughts & experience using TL bullets and whatever lube that you use? BTW I never size the TL cast bullets and have never had any "too big to chamber" issues.
