The process is quite simple and good results certain if you do the following steps.
Send me a swaged pure lead throat slug. (blanks available from LBT for $4 per caliber.) Get push through slugs at the same time and feel out the bore with these. If it isn't perfect as explained in the push through instructions, or if the bore looks cloudy, order the LBT lap kit when you order the mold, and lap it using bullets from the mold purchased.
The best hunting alloy will be wheel weight metal, air cooled or wheel weight with about 2% silver bearing plumbers solder added as a base metal, diluted with fifty to 75% pure lead, then heat treated, or water dropped. Experimenting with the mix until hardness is 16 bhn maximum. (This hardness if potential velocity of the rifle and bullet weight of interest is over 2400 fps using jacketed. If maximum velocity is less than 2400 fps, just just use air cooled wheel weight metal, aged two weeks or more.
Use the slowest powders and charges listed in jacketed manuals, preferably the ball powders. IF YOU ARE USING LBT LUBRICANT!!
Using air cooled and aged WW metal, most other lubes will take velocities to 1800/2000 without leading problems, but LBT lubes will handle velocities to 2400 fps from good barrels. Impact velocity with this hardness (approx 14 bhn) needs to be at least 1600 fps for certain expansion, so you see, to get a good working range, i.e. expansion at longer ranges we need to get the muzzle velocity up to a good 2200 fps, and 2400 is better.
As for bullet weight, and style, in most cases the LBT LFN will be best, but if the throat isn't long enough, and,or, if relitively heavy bullets can be used in the rifle of interest, the LCFN.
Most customers who aren't certain of what style they want are happiest if they let me choose the bullet after I measure up their throat slug. I'll give you what I would use.
