For that 'kinda' money, 'd look @ the Pedersoli or Uberti rifles & the other imports. Esp. if 'ya' want a rifle ASAP.
http://www.davide-pedersoli.com/http://www.uberti.com/Otherwise, I'd look for a Browning BPCR series in either .45-2.1" (AKA .45-70) or .40-65 WCF, which was probably the best BPCR rifle for the bucks. These rifles were designed & built for BPCR silhouette shooting. However, Browning stopped making them. While a previously owned rifle or a NIB are available every so often, they can be just about @ your limit. I've seen them on the various auctions sites & ads for anywhere from US $1200.00 -1400.00.
Sometimes, you'll see a Browning "Traditional Hunter" series rifles for sale, but these are NOT the same rifles. However, Browning did chamber one of those models for a .38-55 WCF & I believe a .45-2.1".
Do you have any reloading &/o casting equipment? Another cost factor that you must consider as these rifles have a large appetite for heavy bullets & @ store-bought prices, they aren't cheap.
A few days ago, there was a thread
