To answer part of your question, I think that $1000 for a 2006 1895 Marlin is a lot of money. These rifles have gone up in price, however not that much unless this rifle were a "vintage" 1895 I wouldn't buy it for a $1000, "vintage-mint" I would probably go $1200 +-. The ammo itself will probably sell for $500 a box on Gun Broker, but not the rifle!!! Also I believe that Remington took the Marlin factory over in 2003 (?) and Remington lowered the standard on their quality control. It would be good if you had stated what the rifle is going to be used for, but......... I started shooting an 1895 Marlin Guide Gun in 45-70 around 4 years ago. lt was a "JM" stamped 2002 vintage gun with an 18 inch (?) compensated barrel. I fired it once at the range, **** near rattled the fillings out of my back teeth, took it home and tamed it down with a "KickEez recoil pad. That rifle was a nice rifle, however I wanted a vintage on, finally found one of Guns International for around $750. That gun was early vintage, came with the 1/2 magazine and a 22 inch barrel. The bluing was good so I left that alone and refinished the stock on the rifle. Both of these rifles were extremely accurate and would shoot better than I could shoot one. I black bear hunt so my shots are not that far of a distance, my rifle is sighted in at 50 yards to hit point of aim. With that said what I have found is that point of impact with a 300 grain bullet, sighted point of aim at 50 yards, will hit point of aim at 100 yards, and from 100 yards to a 200 yard target the bullet will strike 11 inches below point of aim at 200 yards. I don't know about the 45-90 or the 45-100, what I can state is that I cannot imagine needing anything larger than a 45-70 for any game hunted in the U.S.. I shot my first black bear this past season using the 45-70, using a Barnes 300, flat based TSX bullet; the bullet is a hollow-point bullet that looks like a 5 gallon pail sitting on top of the casing. The shot was around 60 yards, broad side shot just behind the shoulder an out the opposite side. The performance of that cartridge and that bullet was total carnage on that bear. I usually hunt black bear with a 35 Whelen with the 225 grain Barnes TSX, the 45-70 has me questioning whether I ought to be taking the 1895 Marlin out instead. I've attached a photo of the exit hole on that last bear that I took with the 45-70, take note of my hand compared to the exit hole.
