"That's why there are gunmakers and proof laws.
Gunmakers know what is what and proff laws make sure they build products to a standard.

If all the gun makers gave out the information you want, then every tom, dick and harry would want to start building guns, taking away some of the market.

500 Nitro"

Yeah I know. However nobody produces a double chambered for a nitro cartirdge that is affordable for folks such as myself. Therefor, we're left to do it on our own. With a family, 3 kids, buying a house, getting deployed, vehicle breakdowns, piss-poor insurance at work, etc., etc. I don't see it being possible to spend several thousand dollars on a rifle for MANY MANY years, if ever. I truly envy those of you that are in a position to spend 10, 15, 20K or more on the double of your choice. Those that can afford to buy a good double aren't the ones that will be building themselves. They will and do spend the money for the workmanship that goes into such a gun. I can save enough to buy a donor action. Then save a few hundred more to do a little work and so on until it's complete. I know people will say that I could just keep saving until I have enough to buy a double but in my reality that isn't possible. Something comes up that takes that money away (see above). Besides, there aren't enough of us that do or would build our own guns to adversely effect the market. I just want to be able to do it safely.
