Yes.
Lyman is (IMNSHO) the best source for what you'll need.
Nobody does lead like Lyman.
Leading is caused by:
1.) Improper and/or insufficient lube
2.) Improper powder - slower burning is better
3.) Improperly sized bullets - .002 over is generally best.
4.) Gas blow by at the base of the bullet.
Hardness of the bullet and velocity have little effect on the tendancy of an otherwise properly loaded lead bullet to leave lead deposits.
I regularly drive very soft swaged lead bullets (.430 dia .44Mag) at velocities which approach 1500/1600 fps out of my Winchester Trapper with no leading whatsoever.
Most commercial lead reloads violate all three of the major causes of leading:
1.) They use a lube which is cheap, sticks well in the grooves for shipping and is easy to apply. This is great for shipping, but not so great as a bullet lube.
2.) Faster burning powders require less powder, therefore are more economical. eg. ~ 8 gr of Bullesye will deliver the same velocity as ~ 17 gr of 2400. when used behind a 240 gr cast or swaged lead .430 dia .44 Mag.
That figures out to a considerable savings since it almost halves the cost of a prime component of mfg. For the average Joe Handloader it isn't a big deal. for a commercial loader that loads millions of rounds a year, it's a huge savings.
3.) One size fits all theory of mfg. Bore sizes are fairly constant across all brands of revolvers. Chamber mouths OTOH, vary considerably.
Don't think so?
Slug you bores and each chamber and see for yourself. Smith's (as a rule) aren't too bad. Colt and Ruger OTOH can be terrible - especially in the .45 Colt.
Anyhow - I'm out of any further discussion of leading. This is the last time I post about it. Why? It's useless to even try to point out the real cause. Sure as shootin, come a week or two and someone will be quick to point out that "going above 1000 fps will cause leading".
*sigh*
