What is the difference between lead bullets and jacketed bullets? I reload with Win. 296 for the .357 and .44 if that matters...
Thank you for any input good people!

One is jacketed, the other isn't. One has lube grooves with a wax based lube in them, the other is bare guilding metal, some have a crimp groove,(called a cannelure).

Me thinks ya need to be more specific in your question. Both types can be used with 296 powder in both cartridges. Cast bullets can be cheaper than jacketed and do the same job.

Sorry. I don't understand why so many reload cast. I thought they could not be loaded as powerful as copper for some reason.

Also....since there is no cannole groove do they crimp as well?
Not to be flippant but jacketed bullets will not lead your bore while lead bullets will unless the right conditions are met. These conditions are bullet size to bore size. Cylinder throat size to bore size. Bullet hardness and appropriate pressure for that hardness as both too little pressure and too much pressure can cause leading.
Lead bullets have less bore resistance and will produce higher velocity with equal powder charges than a jacketed bullet thus its important to use data for lead bullets when loading lead. With the same weight bullet the maximum load for lead will generally be 10% below the maximum jacketed bullet load.
IMO 296 or H110 isn't the best powder for lead bullets being that they're volume sensitive and run velocities at full throttle. There are loads using 296 in the old Winchester data with lead bullets but you need a hard bullet sized correctly with proper sized cylinder throats to avoid severe leading. Unfortunately the only way you can find out if your load leads is to shoot some to see if you need to get out the lead remover or not. Someone who casts their own bullets and has more control over bullet size and how they match their particular revolver can have great success with lead bullets at all levels of velocity.
Current Hodgdon on line data lists no lead bullet loads with W296 or H110 in the .357 mag and only loads with gas checked heavy bullets 325gr ore heavier in the .44 mag. This indicates the difficulty with these powders.
When usng lead bullets most shooters want to be flexible with their loads and generally are looking for less expensive target loads and not heavy thumpers. Medium burn powders like Unique, Universal, HS6 etc. or flexible slower powders like 2400 and AA#9 make a better lead bullet powder.

I shoot strictly cast out of my handguns, and I cast my own. The reason is I find no need for a jacketed bullet. A cast will do anything a jacketed will for a fraction of the cost, and typically, a cast bullet can be loaded to higher velocities than jacketed with equal pressures.
Yes, they crimp as well as jacketed...possibly better. Most cast bullets have a crimp groove, but some semi-wadcutter lead bullets are crimped over the shoulder of the driving band.
Regarding the WW296, I think it's OK in the 44 Mag., but I recall reading a warning in the Winchester manual about using it in the 357 and I believe it warned against shooting reduced loads. In my Lyman 49th Ed. manual, they only show one 357 load for WW296..and it's a max load....no starting load, only a max load. AL2400 would be an ideal powder for upper end loads in your 357 and like Steve said, Unique would be fine for mid-power loads.
