Good morning Big Bore Gurus, Please allow me a question that may be stupid: Is there such a thing as a Beginners Guide to Double Rifle Building? Some website(s) or book(s) covering the basics: the different types of actions, barrels, stock design, putting it all together, regulating the barrels, etc. I've seen scattered information on this forum, but being slow in understanding and short of brain power that only confused me more. Something all-encompassing and comprehensive would be nice. Sort of a framework to guide me on more detailed investigations... Just curious... expanding horizons... trying to learn more about it...

there is a book that walks you through the process of building a double rifle from a shotgun frame. I think the guy who wrote the book lives in colorado. I also believe there is a member of AR who is curently trying to build a rifle using this book for refrence. ****************************************************************** R. Lee Ermey: "The deadliest weapon in the world is a Marine and his rifle." ****************************************************************** We're going to be "gifted" with a health care plan we are forced to purchase and fined if we don't, Which purportedly covers at least ten million more people, without adding a single new doctor, but provides for 16,000 new IRS agents, written by a committee whose chairman says he doesn't understand it, passed by a Congress that didn't read it but exempted themselves from it, and signed by a President, with funding administered by a treasury chief who didn't pay his taxes, for which we'll be taxed for four years before any benefits take effect, by a government which has already bankrupted Social Security and Medicare, all to be overseen by a surgeon general who is obese, and financed by a country that's broke!!!!!

Frans, Brownells has this book for US$50...jim BUILDING DOUBLE RIFLES ON SHOTGUN ACTIONS Mfr: BUNDUKI PUBLISHING W. Ellis Brown. 187 pages. 8½" x 11". Hardcover. Over 250 photographs and illustrations. Well illustrated, easy-to-follow step-by-step instructions guide you through the process of building a custom double rifle on a shotgun action and avoid the expense of a British double rifle. From defining the scope of the project to fitting the barrel to the action, proofing, regulating and finishing, Brown shows you the closely guarded steps of building double rifles, which are not beyond the skills of a good gunsmith. if you're too busy to hunt,you're too busy. | |||

I saw that one, thanks Jim... now the question is, would shotgun actions be strong enough for a .470? I think I might just order one anyway... Frans | |||

Talk to N'gagi who is a member on this site. I think he is building a 470 from this book ****************************************************************** R.

Frans, This sounds like a question for Harald! I think I would build a .450/.400 for this project. I shot one once, and it was a hoot. Very nicely balanced, not much recoil. jim if you're too busy to hunt,you're too busy. | |||

What kind of shotguns would handle the recoil? You dont need to beef up some of the internals? | |||

I'd say this is not a project for a beginner. I can't imagine a more complicated project in reality to do properly. Believe me, I've built about 100 rifles, designed DGR wildcats(including the .600Ok and 12 ga FH) and seen them through to completion and have all the machine tools and skills necessay top build a double rifle, however, I have not attempted it. Can it be done sure, Jeffe did a neat job on his 550 flanged, but there are major issues. To my thinking.I'd be better off buying one that works and won't blow up unexpectedly. Just my 2 cents, best of luck if you give it a go.-Rob Never underestimate the power of stupid people in large numbers to do incredibly stupid things- AH (1941)- Harry Reid (aka Smeagle) 2012 Nothing Up my sleeves but never without a plan and never ever without a surprise! | |||

I recommend you get the book. I am reading it now, and it's very interesting. It is a complex project, but at least you'll get a good idea of what's involved. The author talks about what actions are suitable for various cartridges. Maybe Jeffe will post here, but I believe he indicated in an earlier post that you want to match up total backward thrust of the new cartridge with that of the originally proofed load (pressure x case head diameter I think, haven't got that far yet). Before starting this book, I didn't really understand what the difference between chopper lump barrels and monoblock/demiblock was. Neat book. Highly recommend it. He also addresses using smaller, bushed firing pins for protection in case of primer blowback, etc. Steve | |||

I dropped Harald (Wolf) a line, to figure out how much a 12-issue subscription is these days, I found $110, $120, and $125 on the various pages of his site. Maybe a study of cartridges is a good starting point, and ordering that book... It will probably never happen, but it never hurts to acquire some knowledge about it... Thanks for all the suggestions.

********************************************** Steve, what are a couple of the actions he recomended?? Everyday I beat my own previous record for number of consecutive days I've stayed alive. | |||

Rob Has Jeffe ever posted pictures of his 550 Flanged. It would be interesting to get a look at it. | |||

Al, He recommends actions with "strength" features like third bites, double underlugs, cross bolts, bushed firing pins. He also looks at the cartridge they were originally proofed for compared to the proposed cartridge. He takes the pressure in psi and multiplies by the cartridge base surface (i.e .473 or .532 case head diameter halved to radius, then squared, then times 3.14 pi, then times original proof in psi) to get total applied pressure in pounds for original chambering and makes sure the same calculation for the new cartridge is less or equal. He avoids using BP proofed actions for nitro powder cartridges. He checks to see if he can use the existing set of barrels to make a monoblock, too. Steve | |||
