I hate to be the bearer of bad news but afforable and double rifle are two words that don't usually go together . Try Merkel out of Germany. Not cheap by any stretch but still somewhat below Holland and Holland, Westley Richards and Purdy and the like. Cabelas has a fine gun room on line on their web site that sometimes has a nice used double for a decent price but usually even they are priced at or above market value. I've allways wanted a nice double myself but my housepayment usually gets in the way!
Yeah, found the Bakail (or however its spelled). They do have a double, but only in some common US calibers, the biggest (45-70, 30-06, 308, etc.). Nice looking. Might do one for giggles, but not a supplier in big calibers.
Here is an inexpenive and effective deer feeder I made recently.
No batteries to go dead, no hoisting it up in the tree, plenty of capacity, very easy to fill - so far, I love it.
I have made two of these and they are easy to build.
An empty 55 gallon drum, some 2x4's, some PVC tubing and fittings, a little bit of hardware and some paint - and you are ready to go.
I designed it so you can stand on the lower rung and fill it - the top is about 6.5 feet above the ground.
It holds about 375...
