.44 Special too hot for gun?


Registered Users do not see the above ad.


I wonder if 8.5 gr. Unique behind a 200 gr. Hornady JHP XTP bullet is too hot for my .44 Special Rossi 720. The rounds are pretty tame in a Ruger Super Blackhawk, as you'd expect they'd be, but recoil is pretty hefty in the Rossi, a lot like full bore .44 Mags in the SBH. Fired shells extract normally, however, and they look OK with no signs of stress. Still, the Rossi is a 30-oz. 5-shot K-frame size revolver built in Brazil. It has a 3" heavy barrel and a non-fluted cylinder.

Judging by the data that Alliant provides for the 180 JHC bullet, your load would be near or above max for .44 Special pressure levels.

Would think that that is a bit much...doubt it will take the gun apart, but it will accelerate wear. Don't pay much attention to how a shell extracts, that's more a measure of the smoothness of the chambers than any real indication of pressure, and primers don't start to show pressure signs until well past the max. pressure that Rossi should be subjected to (by about twice).

Total weight doesn't have to equal strenght.. could just tape a bar of lead to it and shoot magnum loads if it were.

Might think on backing that load down aby 1.5 grains or so.

Back when the Charter Bulldog was new, friend of mine had to try the old Keith load of 2400. He survived a few rounds, but didn't finish the cylinderful as thse blood from those wooden grips made the gun too slipery to hold on to. Kind of amazing, but the little gun actually showed no ill effects from the 4 rounds fired. Doesn't make it a sane thing to do.

HOLY CRAP!!! Someone with the exact same .44 I've got! Yours is the only other unfluted 720 I've ever heard of. I thought (and still think) my unfluted 720 is pretty unique...and stylish. Now, on to the load questions...

I believe the 8.5gr Unique / 200gr load is from Speer's 13th, right? But I think the load is for a cast lead bullet, not jacketed. Definitely confirm that before you load any. I do use this recipe in my 720, but I use a 200gr RNFP cast bullet, which keeps the pressure within specs. I've used Unique and the Winchester 210gr Silvertip bullet, but I think the charge weight was considerably less than 8.5gr.

As for other loads in the 720, my primary load is a 250gr Keith bullet over 6.8gr Unique. This is just a hair shy of maximum, and according to the Lyman reloading manual, pressures are well within SAAMI specs. This load shoots a little high, but I've never adjusted the sights on my gun, just adjusted my aim.

Finally, Rossi's are much better than many people give them credit for. I've fired thousands of rounds through my M720 .44 special and M88 .38 special, and both are as tight, smooth, and accurate as the day I bought them....and I bought both used. Furthermore, the 720 is built on Rossi's .357 magnum frame, which is designed for much higher pressures than the 15,000cup that the .44 special generates. Just keep the loads within published specs, and your Rossi will last a lifetime.
