It is often forgotten that shortly after the Chinese invented gun powder for use in festive fireworks someone came up with the idea of using it as a weapon of war. The first projectiles used were rocks, (apparently there was no Obama induced shortage of natural resources back then). It didn't take long to realize that the lack of uniformity, density and scarcity of different caliber rocks in inventory at Walmart meant that a more suitable material for projectiles had to be found. After lots of experimentation over many years that included materials; wood, iron, bronze, copper, etc., it was determined that lead possessed all of the properties needed for an effective gun powder propelled projectile.
Fast forward to modern times, (although Fred, bob2223, Cobra64 and Dudel still remember the days of rock projectiles), and we still recognize lead as being the 'almost perfect' material for projectiles, within certain limitations. It is an abundant natural resource, takes no elaborate equipment to either mine it or mould it and if found after use it can be reused over and over again. (I can think of something else that fits in that category but that discussion is best left for a different kind of forum.)
As technology advanced over the years lead projectiles were faced with certain limitations that necessitated alteration to it's basic configurations... most of those coming about after the evolution of smokeless powders with resulting higher velocities and pressures and the advent of fully automatic firearms.
It should be noted that although 'jackets' of different materials were used to decrease 'lead fouling' and increase accuracy at higher velocities the projectiles still retained their 'lead' core and with only limited exceptions still do to this day.
For the average shooter, especially pistol shooters, lead offers many, many benefits with only a few downsides.
Cost is obviously high on the list... a cast or swaged bullet being less expensive to produce than it's jacketed counterpart. Should a loader decide to cast his own bullets the cost per bullet can be brought down to statistical insignificance after the initial equipment cost is amortized.
Contrary to some assertions lead bullets are every bit as accurate as jacketed bullets when used within their physical limitations, i.e. velocities, bullet configuration, alloy, etc.
The potential effectiveness of lead bullets is demonstrated in the fact they they were used exclusively in warfare until the turn of the last century and have taken down every manner of game on the planet, from the smallest to the largest and most dangerous. It should also be noted that until a witnessed and recorded sniper shot during the Vietnam war the longest sniper shot prior to that occurred during the Civil War, (or as some prefer, the War of Northern Aggression) with a lead Minnie ball, (conical bullet).
For modern day pistol shooting, be it paper, steel or some hunting applications jacketed bullets offer no real advantages over lead in velocities up to around 1200 fps. (this assumes that a given lead bullet configuration and weight will function reliably in a given firearm.)
The one caveat involves the ongoing debate concerning lead bullets out of an OEM Glock barrel. There are many on this forum who will argue both sides of that debate and I shall leave it to those who are more knowledgeable on the subject than I.
So, the choice is your... shoot jacketed bullets and only have to worry about the added cost and some copper barrel fouling or shoot lead bullets at lower cost and spend a minute or two longer cleaning your guns and experience a bit more smoke while shooting from the lube on the bullet.
What ever you choose, be safe and happy shooting.
