Loading with jacketed is very straight forward, and for the most part because jacketed data is very standardized. Lead requires multiple criteria to be taken into consideration such as, bullet style, bullet diameter, and lead hardness, to mention just a few, then matching up load data with the specifics of the lead bullet characteristics and profile. And then velocities are a concern with lead, and must be matched up with the size and hardness of the bullet too. So it involves more than I care to indulge in, but that's just me, as I have found that wuite a few more reloaders use lead than jacketed bullets.
Jacketed is usually as simple as finding the powder data that applies to that weight bullet. It's for this reason among others, that I have never loaded with anything but jacketed. Though it is more expensive to load jacketed, I still find it to be significantly less expensive than buying a box of jacketed, in most cases. I often locate bulk deals for jacketed, even during these tough times we are currently experiencing I have been able to load for .357, 9mm, and .40 for about 50% or more under retail prices. Not to mention that the quality of my loads verses factory, is exceptionally better, especially when getting into self defense JHP's. Stuff like Gold Dots, XTP's, Golden Saber and the like will often go for $1 or more per round retail, verses .30 -.40 per round for my reloads of at least matched quality, or better.
Oh, and jacketed doesn't trash your gun with lead fouling, and smokey loads are the standard and often severe when loading lead.
