Thanks, Just to get on the same page. With the tumble lube mold I don't have to size right? I can go from the mold to lubing then to loading?
Hi,
The answer to your question is a definite "maybe!"
I've used a number of Lee molds, including a couple of the TL models, though not the one you mentioned. In my experience (read "YMMV"), the alloy and casting temp have affected the final sizing enough that I DO size 'em all today. Just as an example, I have a 124 gr LRN mold for the 9mm, nominal size .356". With straight wheelweights over a Coleman stove that needs some fiddling about with the flame now and then, it will produce a .357"-.358" bullet, which I found works beautifully in a .38 Spl case "straight from the mold", but causes some lumps and bumps in a 9mm case. Same mold, commercial hardball alloy, run at a more consistent temp in electric casting pot where it's "set it and forget it": they're almost dead on to the .356 spec.
So... there's only one way you'll know! Heat up some lead, make some bullets, then put your caliper to work! If you do need to size 'em, the Lee push thru sizing kits are inexpensive and do a fine job on tumble lubed bullets. It's suggested you lube 'em first so they don't stick in the sizer, size 'em, then lube 'em again to replace the lube that was rubbed off in sizing, but you can play around to find what works best for you.
