About your cancer problem. You and all readers. Look hard into the natural cures which are well known, and by this I DO NOT mean any clinic which uses cemo, radiation, or surgery. I've known several people who cleaned up agressive cancers quickly, or slowly, but always effectively, with no death threats. Natural cure means to help the body heal itself with it's own power, by assisting it nutritionally and with cleanup.
Now, the important thing you are asking. I've sold many LDFN's in 170 gr for both 30-30 and 32 winchesters, with all customers being delighted. No need to alter the throat at all. It fits them as they are. Use this bullet with air cooled wheel weight bullets +1% tin, which will produce about 12 bhn, and drive them at about 2200 fps. It will be easy to get excellent accuracy at this speed with the soft alloy if you use LBT bullet lube. Or, if you want maximum power, air cool by placing a fan so it blows across the bullets, and cast in cool temps, preferably 60 deg or lower. This will produce about 14 bhn after two weeks aging, and be capable of excellent accuracy at speeds to well over 2400 fps. This is hunting info that applies to all 30 caliber, 32/8MM etc rifles in fact. The LCFN has a superb ballistic coeficient so it will expand with these soft alloys at ranges out to at least 200 yards with a 2200 fps start velocity and 12 bhn or our to 300 with a 2400 fps 14 bhn alloy.
The DV does apply with smaller calibers but you'll probably get some bullet breakup with close range hits, and velocity has to be pretty frisky to get a good wound diameter. Better to make bullets that expand like quality jacketed bullets, which the above will.
