Re: where do most of you get your bullets ?
My repsonse was for newer shooters than you. You obviously have taken the effort to learn how to get lead to not plate out on the bore. I think few here, especially someone new to shooting, will bother to follow the steps required to assure bore's don't lead. I have no interest in fire lapping the bores of my 25 handguns to shoot lead bullets that are only pennies less than plated (copper flashed or whatever) that don't stick lead to the bore. I also have done casting years ago and found it NOT enough rewarding either financially or to give me any sense of accomplishment that the rest of reloading does. So I will not cast myself and I think few other will when bulk cast bullets (copper flashed or not) are so inexpensive. There is also the lead fumes risk that I will not subject myself to.
The fact is if you do not do what you suggest and what the book you sugested documents, you'll get lead in the bore and it's not that easy to get out. For me and the rest of us that haven't been shooting 40+ years we'll buy the copper plated bullet and minimise the rest of the work that casting bullets require.
I'm sorry you don't agree with my viewpoint. You don't have to because all this is just my opinion. Others might, so I present my experiences. You are free to present yours too which you did. I do not doubt that what you say works. I and maybe others may like to find other easier ways to enjoy shooting.
By the way I'm five years older than you and helped friends cast bullet in the early 1960's. So I've been there, done that! And I won't be doing it again! But you can! I would only ask that when you tell people lead is easy to get out of a barrel you give them the rest of the story about low velocities, fire lapping guns, and the handfull of other requirements that are not intuitively obvious, even to us older hands at reloaders.
This is all my opinion and nothing more. Everyone is entitled to an opinion. Those that visit here can take my infomation or leave it. Frankly, I don't care which. But it all works for me and it may work for others too.
If you are so enthusiastic about your methods for no-leading of barrels, may I suggest you write a "How To" article and offer it whenever the subject comes up. I do that on several subjects that interest me. I make the articles detailed and complete and require Email delivery to those interested, because they are so long compared to what can be posted here. I personally would be interested in seeing your approach but not interested enough to chase down articles and read whole books on the subject. I think that might also be the view of others ... we need a condensed version. Please think about doing it.
