I have had very good luck shooting cast bullets in microgroove in a Marlin 336. I use wheel weights and drop them out of the mold into cool water to quench them. This makes them considerably harder. You can push these up to close to 2000 fps without "stripping" the bullet. Light loads will be very accurate. For what it is worth, I use Lee 150s and Lee 130,s. I think the 130 mold is no longer listed but may be available. The 130 is a very good varmint bullet. Will take deer as well.
If you try to push these bullets at jacketed bullet velocities, the old "microgrooves wont shoot cast bullets" wives tales will prove to be absolutely true. If you back off a bit you will have no problems and will have bullets that kill as well as as jacketed, and will not strip and fly off erratically, nor will they "lead" your barrel.
The simplest lube that actually works, that I know of is the Liquid Alox sold by Lee. Just put the unlubed bullets in a bowl, ad a SMALL amount of Liquid Alox and hand tumble them for a few minutes. Soon, all will be covered with lube. Set out to dry for a couple of days and load 'em up!
Stand them on their bases on a sheet of waxed paper to dry.
