Hello,
I was wondering if any other owners of the John Ross 500 Magnum are having tight throat issues? My throats pin at .499 and my bore is .5014. I sent the firearm back to S&W and they said it's within there specs after firing a full cylinder threw it. I'm wondering if I should have the throats reamed so the bullets aren't undersized going down the barrel. Thanks for any comments and advice. Boats

From what I have heard, this is a common issue with the JR 500s. I got mine 2nd hand, but the previous owner said the throats were originally .498". He had Jim Stroh ream the cylinder throats to .5005". Fermin Garza (2Dogs on this forum) would be another who could take care of this for you.

Maybe the pressures are high enough to obturate the bullets in the forcing cone of the barrel and keep them from leading, in spite of being undersized, but reaming the throats is always a good idea. I met John several times in the early 1980s, as we both used the same gunsmith. He truly loved the big bores, and hunted in Africa with a Manton 4-bore double rifle that weighed 24 pounds, taking buffalo and elephant with it. Another interesting thing about his reloading is that when he wanted to download the 500 S&W, instead of using a lighter load of a faster powder he just filled the case with a slower powder. He liked 100% density in his loadings.

Smith & Wesson's reply to my issue.
thank you for the inquiry, Unfortunately we cannot provide the specs as to the measurements. It is though, designed in the way you see it, This does not mean you should be using anything other than factory ammunition per what the caliber calls for. Please use a .500 magnum caliber bullet, with 440 as your max grain. We do not recommend you attempt to put an undersized or oversized bullet through the barrel.
We only recommend using SAAMI approved factory ammunition in our firearms. The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) is an association of the nation's leading manufacturers of firearms, ammunition and components.

I had one of these guns a few years back with narrow throats and it loaded horribly with the light loads that I used and I couldn’t get the accuracy that the gun should have been able to produce., it soured me on the revolver and I ended up selling it. Send the cylinder off to the guy that hones the throats and it will shoot great afterward.
I will say that I found the recoil and weight oppressive which was another reason I let it go. They are a beautifully made revolver.

Yes, that letter sounds to me like they're saying, thanks for buying our product, but we already made money on it, and we're done here, deal with it.

I wonder if he got a tracker to carry it for him.

I'm not sure about that, but I know he liked to shoot it sitting, resting on both knees drawn up. The recoil just rolled him over onto his back, making it very comfortable to shoot . . . so he said!
