HollowPoint: I must say I'm not real interested in synthetic tips, but if I was, I still wouldn't send you $2.00 for your info. You did lots of development work picking the brains of many folks here on the forum. Where would this forum be if everyone that had an idea for something after discussing it for over 3 pages decided to sell the info, rather than just posting it openly in the forum? There are so many people here that have done things to promote cast boolit shooting, that just gave away their ideas. What if Beagle said "Send me $2.00 and I'll send you info on making your moulds cast a boolit that's larger in diameter than it's currently casting"? Or if Ken said "You want to post more than 100 postings, then the charge to do that is $5.00 per hundred messages" or any other of the many folks that have made contributions to the cast boolit world? Now if you wanted to actually build tip moulds, and sell those, I would see no problem with that, but what you're basically doing is saying "I had an idea of how to do this, and after bouncing it around with several forum members, I've come up with a way anyone can make a mould for themselves, and for just $2.00 I'll send you a PDF file of how to do it." and I personally think that stinks. If you were to post how to do it here for anyone to see, then said you also had a PDF that explains how to do it in detail that you want to sell, I would again have no problem with that, and I bet you would still sell as many as you have, maybe a few more, or a few less, but it would come across MUCH better that way.
As I said in the beginning, I have no plans on making boolit tips synthetic or otherwise, so what you're doing doesn't matter to me one way or the other, just think of all the good things that have come out of this forum, and where they would be if everyone did as you're doing, selling copies of your idea. (for any amount of money, the amount isn't the issue)
I might be way off base, but I'll bet that there are other forum members that had/have the same thoughts I do, but didn't want to say anything.
