Vic1...I may be able to encourage you to continue as i cast and use alot of bullets as I'm in the cast bullet business so I can give my .02cents....It is very rare to get good accuracy, no leading,etc. the very first mold or the very first time.....accuracy with cast can be much harder to achieve then with j-word bullets...many things come into play, bore size, bullet design vs. chamber leade, bullet hardness, length relative to twist rate, portion of bullet not supported by rifling, etc.....get a few diff. 30 cal molds and the means to size bullets to a few diff. sizes. and experiment...I would suggest Lyman #311041, or #311299(the borerider), or my favorite #311332, Saeco's #315 is another as are the RCBS sillywet designs. Try then sized .309 and .310" to start and my old standby load of 19.5grs. 4759, try diff. OALs, only make one change at a time and enjoy your journey into accurate cast bullet shooting, it will reward you!!
