If having too many guns means there some in the back of the safe that never get shot then I am guilty. Most of those are CF's and I'm considering selling a couple, possibly to finance parts for another flintlock.
My black powder guns I've done a little differently. I had several production guns stuck in my gun closet, too long for the safe, that I intended to keep. But when I built my first flintlock, an Isacc Haines .54 from TOW, and spent some time shooting it I was forever corrupted. That stock was the most comfortable and best fitting stock I'd ever shouldered and it seemed to cut the recoil of heavy loads in half. So I built another one just like it but in a B weight barrel and .40 caliber. They almost feel identical except the B is a tad heavier and has set triggers. Almost like having just one gun.
After awhile I sold all the other ML's because I had no desire to shoot any of them.
I don't claim to be a gun builder but several years ago I was in a large deer hunting lease and a member approached me about building him a rifle just like mine. I ended up building 3, one for his dad, and another for a family friend. Starting with my first, each rifle was better than the one before. By that I mean I was finally getting a handle on the architecture and some basic decoration. So I'm wanting to build one more (well, at least one) rifle. Either a B weight in .50 caliber, or another .54 with better wood. It will have the exact same stock as my others as close as I can make it.
See what I'm doing here? I planned on building 2 identical feeling rifles, a large bore and a small bore, to cover all my shooting needs from squirrels to turkey to deer and elk. But what am I doing, I'm already feeling obsessed to build another when I can only shoot one at a time. I tell you, it's a disease.
