Another solution to a fast 357 is 356 GNR. A 41 Mag. necked to 357. Starline 41 mag cases, Swift 158gr. bullet, 22.5 gr. H-110, CCI LPM primers. 1650fps from 6.5 Ruger Blackhawk.

Alcorn is right about this. We actually hunted together in Africa in 2018. I took my 356 GNR on that trip and took a nice Impala at 122 yards using the 180 grn XTP Bullets.

Thanks for chiming in everyone. Sounds like it's Freedom-Arms-Only loading. That's fair enough. Cant afford one at this time so I will listen to Mr. Taffin and stick to normal loads unless I hand over the cash for a Freedom Arms. I love hot loads but have no interest in blowing up a revolver... Or myself. Special thank you to Mr. Bradshaw and Mr. Taffin for contributing to the thread. Mr Taffin, the article on the .353 was a hell of a good read! The BFR can handle those levels as well and long cylinder allows for long bullets. The new 6 shots can handle it?

I would think so, the bfr cylinders are about the same size as my oversized blackhawk cylinder which I run 353 level loads without issue. I just tested some way above book max aa9 loads with the 180xtp at normal 357 OAL. 16g aa9 with a cci400 in fed brass @ 1.580" and got 1539fps/946lbs without cases sticking. Pretty impressive load.

When you say oversized cylinder, is it a custom cylinder? What length barrel is that out of? Is 16 grains of AA9 a compressed load? That's 4 grains over max by my reading!

I just got an email back from Magnum Research and they said they don't see an issue with their new 357s shooting 353 Casull loads. This was a customer service rep telling me they had talked it over with one of their gunsmiths, not me talking directly to them.

Yes it's a 6.5" gun with custom oversized 6 shot cylinder from Gary Reeder (it's pictured above in the thread). Yes it's way over book max and is slightly compressed at 16g. Also for fun I worked up to 22g aa9 with a 125xtp and got 1966fps/1073lbs loaded at 1.582" OAL. Loading long (1.805") with a full case of 296 I ran a 180g cast WFN at 1806fps/1303lbs from the 6.5" barrel which has been the hottest load I've run and probably wont try for any more. Cases were a little sticky at that level, but I had dirty chambers by then so that may have contributed to the sticking. All my loads are with small rifle primers, CCI400s with the aa9 loads and CCI450s with the 296.

Oh, sorry I just saw the picture but didnt put two and two together. Do you mind if I ask what that ran you as far as cost? Those are some screaming numbers for sure. I've always been a little timid when using AA9, it's always seemed a bit spikey to me. Very impressive nonetheless.

Now that I bought a FA 357 the link to Taffin's data isn't working. Anyone have the info that they could share?

Pressure climbs as we pour on more powder. This includes slow powders. With faster powders PRESSURE SPIKES much faster. From pressure spike we go to DETONATION, which is not at all a PROGRESSIVE BURN. The distinction between BURN and DETONATION is a no-man’s land with less distinct edges than the barbed wire bordering an East German mine field. A delineated minefield is one thing, an unmarked minefield quite another. There is no reason to turn a loading bench into an unmarked minefield.
Just as the cartridge case is the head gasket of a cartridge firearm, the bullet is the piston, or relief valve. If the bullet (or piston) cannot be set in motion fast enough to cushion pressure rise, pressure finds another way out. Thanks to design, mass, metallurgy, tolerances, guns vary in strength. These dimensions and mass determine how well a case holds up. Reloading life of the best brass shortens when we redline our loads. The best brass in the tightest chamber withstands only so much pressure before its shock-absorbing structure embrittles, or flows.
Cartridges have been developed outside any consideration for reloading. The brass is a one-shot deal.
I was astounded at some of the pressures we fired in Ruger SRM prototypes. Remington couldn’t believe Bill Ruger, Jr., and I were shooting this stuff in hand-held revolvers! Remington even turned down Bill’s offer to send a revolver or two----or more----for ammunition development in Lonoke, Arkansas. Some of the brass could not be reloaded. And don’t ask whether it drops out of the chamber!
On Singleactions we have a diverse group of firearms folk, representing collecting, custom, hunting, gunsmithing, marksmanship and, of course, hand loading. Always, there is an individual who wants more, more bullet, more velocity, more of both in a smaller gun, etc. Our own Ronnie Wells has pushed the envelope in nitro funny car drag racing, where combustion pressures run so high, so hot, so erosive, that most of the motor is turned to junk in 4-seconds! Think of rebuilding your revolver after ONE SHOT!
I try to squeeze each shot like it’s the only one I have. To keep the bullet between the goal posts, as it were. Some of us, and I know personally it includes the likes of John Taffin, Dick Thompson, Lee Martin, and this shooter, know we can have guns & loads which take the beating better than our bodies do....
For this shooter, it all comes around to the target. Permit me to define that abstraction----“the TARGET”----as a challenge to be repeated, over & over. Consistency is not a one-shot deal. David Bradshaw

Mr. Bradshaw,
As expected, your very insightful response is very much appreciated. I honestly was curious about the .353 Casull after reading Mr. Taffin's article. As usual, it was a fascinating read. But, even if MRI says their BFR in .357 can handle the .353 Casull, as you illustrated, it is really pushing the limits. It's not something I want to test at this point without brand new brass each time, and most importantly, a Freedom Arms revolver. I think I'll just skip it altogether.
I love seeing what something can do, but if I've learned anything from reading you, Lee, and Mr. Taffin, knowing how to stay safe is far more important. There are safer ways to get more performance without unnecessary risk.
But you have to admit, reading Mr. Taffin's article on the .353 Casull was a really exciting read!

But you have to admit, reading Mr. Taffin's article on the .353 Casull was a really exciting read! ***** Quick Draw McGraw.... thank you for the kind words. Dick Casull helped ratchet the pressure caper with his revolver and cartridge. Dick as much as exhorted me to mound slow powder over the case, drag a poker card across the case mouth, and “seat” a bullet. This was for my .44 Mag, the first Model 1983 that wasn’t a .454 Casull. I took Dick’s word for the strength of his 5-shooter, my hand still in the shock stage of shooting anti-aircraft loads in his 12-inch octagon .454. There is no point push velocity without a tight cylinder/barrel gap. Other details which kill velocity include excessive forcing cone and this biggie----oversize chamber exits. And then there is barrel length. If the pressure dome spills outside the muzzle, either the barrel length, bullet weight, or case itself is wrong. Head-cracking concussion results----without velocity payoff. In my humble opinion, theses sound waves don’t need ears to enter the body. Given revolvers of equal dimension, and aside from bulk, a longer barrel provides free velocity. with Freedom Arms, just having the revolver gives us free velocity. David Bradshaw

[quote author=" bradshaw" source=" looked up “.353 Casull,” could not find diddly. Freedom Arms chambered the Model 83 in .357 Mag and called it the Model 353. Quite a far cry from a “.353 Casull.” My 353 is labeled as 353 Casull as I believe all the early ones were. But the cartridge markings are 357 magnum.
