I added one of these barrels .450 Marlin to my H&R Ultra .243. Very nice, has a crown and ejector. I put a Visionking 1.5x5 scope on it.
I can shoot cloverleaf patten at 100yards with Hornady Leverevolution, kicks pretty hard but I'am very happy. Shouldn't have any problems taking deer, bear or moose with the .450 Marlin.
The 450M isn't real popular, it's only available as an accessory barrel, and last I checked, is one of the few if any rifle barrels that H&R has that still has an ejector, at least until they run out of the current run of barrels. One of the 450M issues that most shooter don't care for is the recoil of factory ammo, there are no "trapdoor" level loads, they're all levergun or level two loads, the milder recoil of the trapdoor factory loads of the 45-70 us what make it very popular. The 450M's forte is stout factory loads being available, but for a handloader, the 45-70 can match it in levergun loads, or exceed it in Ruger data.
I have 2 450 handi barrels. One is 22" and one is 18" with a brake. They are both good shooters.
Posted by: dumgunny --->The .450 Marlin......one of those awesome solutions to a non-existent problem! Maybe YOUR non-existent problem, but I think a lot of people are in the same boat as me. I don't reload and I want the biggest bang for the buck. Sure you can load 45-70 shells to the same levels, but for people like me who don't reload, it is nice to be able to buy a box of 325 grain ballistic tip ammo that shoots 2250fps for around $30 a box. (the price on hornady's site says $39.95 a box, but it is still $28 at my local source) Commercial loaded 45-70 ammo with this kind of power (buffalo bore) costs 50% more. Commercially loaded 500s&w ammo costs almost twice that of the hornady 450marlin ammo with not much more power. Availability is the only downside to buying 450 ammo. If you don't live near a Gander Mountain or Cabelas, it may be hard to find.
The recoil is not for a gun-shy person. It is in the neighborhood of 12ga turkey load recoil. With a good buttstock pad, a heavy jacket, and offhand shooting while hunting it isn't bad. At the range, hunched over a benchrest with nothing but a t-shirt is a far different story. The first time I shot my 450 handi, I fired 3 rounds and went home with a purple shoulder. That said, a good scope is required on the 450.
So many people here rag on the 450 when ever it is brought up. I don't know if they ever owned one, but it is a fun gun and a lot more practical than some other calibers that have been made for the handi.
my 450 is my #1 shooter with are without factory loads. I do not advise shooting deer long ways with a 500gr pure lead bullet. I did this,this season and the hole out of one of the hams was the size of a soft ball. Hit the front and out the back of a big Doe.
