I used to buy old 80's and 90's plastic stock ADL 700's in .270 and .30-06 for $200-250 all day long. I'd snatch them apart, order the BDL conversion parts and a barrel blank, take it all to the gunsmith and let him do his magic. Then I'd bring it back home, and do a trigger job myself on that old Walker/Remington wide-shoe trigger, and never have to spend a dime on that part of the build. I'd be all-in for less than $1,000 for a custom rifle. I miss those days... That was just 8-10 years ago things were like that. Now everything is ridiculous.
You might stumble upon one in a small mom & pop pawn shop in a small town for that cheap. If you do, buy it and build you a .25-06 AI, but make sure it's the 40º version. If you do, shoot me a PM, and I'll be glad to help share some tips and tricks for making your life MUCH simpler when prepping brass and fire-forming brass the easy way. I spent years with that trial & error, but I don't mind sharing the knowledge.
