45 win mag

I am curious if anyone has rechambered a blackhawk in 45 winchester magnum. I have a 45 convertable and thought about rechambering the 45 acp to the magnum. I know the its in the same pressure class as the 44 mag, so....... Any thoughts would help.

Why would you want to, when the 45 Colt magnum (+P) loads are available from Corbon and Buffalo bore? If either of these optiuns isn't powerful enough for you there is always the 454 Casull........Just say-n

Interesting thought... I love me some hand cannons, wildcats and oddballs so you have me curious. From what I could tell, you would be hitting the higher end of .44 Mag with .45 Win Mag, and I can tell you that a steady diet of heavy loads through a BH will lead to some serious wear and tear. From my experience the screws are the weakest part - I've snapped a couple. I'd like to hear the thoughts of some of our more knowledgeable/experienced members on this subject. If safe, I think it would make a great novelty for occasional grins, but I'd keep my regular cannon plinking to my Casull, Auto Mag, S&W 500 and others designed for it.

Considering how many BH were converted to 454 Casull,475 and 500 Limbaugh with no problem I see no problem.Can't see how a good screw would break on the grip frame

Since I know part number xr01900 and xr03300 for my .44 off the top of my head, I can attest to the fact that they can be broken by heavy loads, even when I check and make sure they are tight between shots. Also I have to be regularly tighten the base pin and tap the pin for the rear sight back in. It is along the same lines of saying that you may not blow your engine when you red line, but if you do it consistently you will eventually wind up with a higher maintenance bill.

Most of those conversions are done with a custom 5 shot cylinder. I would think twice about rechambering a 6 shot cylinder to .45 magnum. Even though the pressures are the same as a 44 mag. the .45 cylinder walls are thinner.

I would love to see Ruger make a 45 Win Mag autopistol...perhaps one with adjustable gas action and interchangable barrels calibers similar to the Wildey magnum!!!

At one time I had over 1500 45 Win Mag brass and looked for a 45 ACP cylinder to have re-chambered. Never found a cylinder so I sold the brass.

Blackhawk in 45 win mag

I have a blackhawk convertible 45LC with a 45 ACP cylinder and a 45 win mag cylinder. I thought I had the only one in the world. It shoots great but is redundant. I have about 300 pieces of 45 WM brass, I loaded them up about 20 years ago, test fired a few and put them back on the shelf. They are sitting there today still loaded. The loads are 255 casts gc at 1000fps and 250 jackets at 1200 fps.

You cant do anything with that that you cant do with another chambering that has more readily available brass. I have a blackhawk and a super blackhawk in 44 mag. that will do the same thing, brass is cheaper and easier to get.

If you want one go for it. It is fun to shoot but kind of pointless.

As an aside at one time LAR made a Grizzly autoloader in Win Mag along the lines of a 1911 pistol.

I had a 45 acp cylinder rechambered to 45 win mag when the round came out. I put about 3k of rounds through it. No problem. I stopped when the round became hard to find.
