RE: Lube or not lube conicals ?
Yes it is important to lube the R.E.A.L. conicals. It will help to keep the bore of your rifle getting leaded up. Bore butter will work, Crisco Shortening will work, even a combination of wax melted andmixed with olive oilwill work.
I shoot them with 80 grains of 2f powder. Some people put a bore button under them and some don't. Only your rifle will tell you what you like.
