No my only reference to the model 597 Remington is for a 22lr semi-auto rifle.
New they are between $150-170, they don't have a fantastic reputation...

You will have to contact barrel makers or visit their web sites to see if anyone is making them or would be willing to. Jarvis makes aftermarket "Bull" barrels for the Remington 597 in .22lr, but they no longer make the .22 Magnum barrel - I bought the last one a year ago
