    Yes!

    In General, Jacketed Bullets provide higher velocity capability at higher pressures, particularly in Rifles. Expansion with Semi-Jacketed or Jacketed Hollowpoint Bullets is also enhanced with the Higher Velocities.

    Lead tends to penetrate deeper than jacketed.

    Yes, there are differences. Here are a few I've found:

    Cast and swedged lead bullets tend to cost less.

    Jacketed bullets tend to be easier to develope accurate loads with. (IME)

    Jacketed bullets tend to foul your barrel less.

    Lead bullets can be found in semi-wadcutter and large meplat flat nose designs for great on-game performance.

    Loaded to equal pressures lead bullets are faster than jacketed.

    Lead bullets are easier and cheaper to make on your own.

    I agree with treg on the less fouling angle. In fact, whenever I load up a batch of lead bullets for the range, even though they're just for target shooting, I always load up about 10 or so FMJs or JSPs. (I'd do more, but they're getting so damned expensive). I'll fire them last to "clean" the barrel. I find I have to do less scrubbing that way. If the leads are 38s, they seem to foul my M66 badly, and I'll shoot about 10 357 mag FMJs to clean it up somewhat. YMMV.

    Same as Chuck. When I use to shoot lead bullets I always followed up with a few rounds of copper jacketed bullets to 'scrub' the barrel. Since then I spend a little extra money for the copper plated lead bullets.

    When I first started loading, got a box of 500 LRN, and shot them rather quick.
    Did follow with FMJ to somewhat clean the lead out, but I quit shooting lead after that.
    I liked the performance of the higher loaded FMJ rds, even for practice.
    Usually I load them rather hot, but not to the max, got tired of throwing brass away.

    For practice and reduced loads I've been using copper plated. If kept under 1400fps there's no chance of leading in most cases. I can load them to most JHP START speeds and pressures w/o any issues.

    But I usually run reduced loads for practice etc. Brass lasts forever this way as I also use a light crimp. (JHP need heavy crimp with heavy loads etc)
    Very cost effective and tidy.

    The 'X-treme' copper-plated bullets make a really nice 'factory looking' round too. Less lead exposure too (minor fine point).
