Sam is going into his 3rd year of engineering school, and I've been sending him these test results.

He wrote, today: "Well I gave it a read and thought about it a bit, and I was curious about one thing. Why are cast bullets less accurate than factory made bullets? What's your hypothesis? Do you think it's just because there's more margin of error with cast lead? Is it more difficult to control quality? "

I responded: "Now, do this for me. search "jacketed rifle bullet pictures", then "cast rifle bullet pictures", look at them and comment back to me."

Joe: What about paper patched bullets? Where if at all do they fit in this scenario? Personally ,my results with paper patching really haven't been worth the effort, but I mess with it every now and then. Some claim really good accuracy with paper patched CB's.

Are there any replies yet, after your feedback?

Ross, I don't know. After the Harrison book came out, I, and many others, tried paper patching bullets. One of my tries was in a big bore trap door and a small Lyman 405. I just never got the knack of it, and gave up. Some guys claimed great success. Maybe that's the secret, paper patching. I don't know.

Not yet. Try doing what I suggested, the search and look. Make believe you've never seen a bullet before. What thoughts?

... a few years ago i was trying to develop a better carburetor for toy cars ... stumped ... until a welder guy stopped, looked over my shoulder, and said essentially "  why don't you exchange part a and part b ?? " ... duh ... on to fame and glory ... ..... 

..and so there is hope that a fresh look by the outside world at the cast bullet enigma will give us a tremendous gain in reliable and predictable accuracy ... hmmm ... where is that welder guy ?? ...

Very good Ken. I have over 50 years of lead bullet shooting, so my mind is pretty boxed in. I am looking for the guy with a fresh idea. But it ain't going to be me.

What I'm looking for is a "Wheels on luggage" idea.

I don't use jacketed bullets! Am I missing something?

Only the target.

After looking at the pictures, I can tell that the jacketed bullet would probably be less malleable because of the jacket. I feel as if the cast bullet could have a higher possibility of tumbling because of it's shape, just because the tip doesn't seem to be pointed and there isn't much of a boat tail, however many bullets are like this and the rifling takes tumbling into account. I believe the aerodynamics of the cast bullet could also alter it's trajectory. These are just some of my ideas, I'm no physicist, but I feel as if the jacketed bullet would stay together better during flight
