I have done several pound casts of some of my rifles but have never been satisfied with the results. I have been meaning to start processing my milsurps but have hesitated because of poor results. I went to another post that explained in detail how to do a good pound cast:
http://castboolits.gunloads.com/showthread.php?356251-Pound-Cast-instructions-(for-rifle-chamber)
The questions that came up are related to what to use as a slug. I usually try to use a boolit but the grooves make it hard to determine the parts of the throat and measure them. I tried one time to make a slug by drilling a hole in a piece of hard wood but the heat of the molten lead left such a rough surface that the pounding didn't smooth it out.
Geargnasher(former member here) recommended a slug 1/2" longer than the longest boolit you intended to shoot. Since I plan to primarily shoot 3XX299 boolits in these rifles, I don't have a mold that casts a boolit 1/2" longer. The Lee TL309-230-5R(link:https://leeprecision.com/cgi-data/instruct/90307.pdf) looks like the only thing that comes close. Being tumble lube means that there are no deep grooves to interfere with measuring. Even if it is not 1/2" longer than I'm still thinking it might be the best way to go since most of my milsurps are close to .30 cal. Lee 2 cavity molds are relatively inexpensive.
Comments on this plan would be welcome.
