I pretty much agree with Dand on most of what he said. I' ve used Lyman M dies for years, on most of my cast bullet rifle work. I've also got the Lee universal expanding die--in fact a couple of them. These have an internal plug adjustment for short and long cartridges, so over time I've acquired two. You don't need much of a flare of case mouths, but like any reloading procedure, deburring and sometimes trimming needs doing. So's inside-neck lubing, but go easy with this. I need to try an RCBS x-die in 30-30. Dand's comment has me interested. I shoot a lot of cast bullets through my 30-30's (Winnie and Marlin--don't have a handi). I shoot jacketed through some of these guns as well, but find that doing this has zero cleaning properties. Use some Kroil, a bore brush, and some patches instead.
I use the Lee Factory Crimp dies for nearly all of my rifle reloading. If you use the crimp feature in a seating die, be aware that you're not only crimping, but pushing the bullet further into the case at the same time. 115 grain lead bullets are fine plinker and small game bullets. There's plenty of published data for them. Reasonable loads with a properly fitted lead bullet usually won't cause leading problems. Lastly, don't overlook cast bullets for hunting applications, and don't think that just because the velocity isn't of a whizzy-bang nature, that cast bullets aren't game killers. There's a lot of penetration with those lead bullets loping along at 1500 fps or so, and has been for over a century and a half.
