a much stronger case. There were still a lot of the old balloon head cases around when I first started working with wildcat cartridges so I stayed with the 44 mag.
Of course his .410 and .429 GNR's are on the .454 case

which is only an elongated and more robust .45 Colt case. Then he has the rounds on the .460 S&W which is the aforementioned lengthened even greater.
The .38-40 and .44-40 are very close to .45 Colt cases necked to .400 and .427, but not exactly. You can do wild and dangerous things hot loading them in modern strong firearms. Not a practice I truly condone, especially since I like the old antique guns too. I might mix them.
that 454 case was designed to handle extremely hot rounds

Bob Baker told me once they had tested the guns and cases up to 90,000 PSI. And if I remember right John taffin had done an article on the 454 and some of the ammo was hitting 70,000 PSI, and that is hot.
So my 410 GNR and 429 GNR are mild compared to those rounds. They are still too hot for a standard size 6 shot cylinder but a good well made 5 shot cylinder handles them very well. Nothing is idiot proof but using loads listed in the reloading manual your pressures are fine. Hot but OK.
I really like the 410 GNR. May add another one day

which work fine. I have a Super Red Hawk in .429 and I have tried small rifle primers which did not work. I think the Remington #7-1/2 small rifle BR primers MAY have worked but I can't really remember. Why risk it. Lot to lot primer cup hardness can vary, I have see that in years past. Using small pistol primers will give some sense of security.
I have a 356 GNR. With spare cylinder in 357

In the works in a Southern Pride package right now. Wanting yo move up, I have two Model 629's, one 5" and a scoped 8 3/8" bbl. Just use the equivalent of 44 Spl +P loads in them. Thinking my next one might be a 429 GNR with a 44 mag cylinder too. At the spring HHC in 2017 a couple of guys were having misfires with their 429 loads. Never did find out what the issue was.
the 454 case is intended to use small rifle primers

but if your revolver has has a smoother action job, the hammer fall might not be hard enough to set off a rifle primer which is much harder than a pistol primer. I normally tell people to use small pistol magnum primers in the 410 GNR or 429 GNR. The Freedom Arms revolver in 454 has a real stiff hammer spring from the factory which has no problem setting the small rifle primer off, but if we give it a slick action job, then we have a potential misfire problem. So if you load for the 410 GNR or 429 GNR and have an action job on your revolver, switch to small pistol magnum primers.
10-4, it will be one of your package guns so magnum

Pistol primers it will be. It will give me time to decide between the 410 and 429 while waiting on you to finish my Southern Pride eith Magnum grip frame. Gave Jr my Bisley 356 GNR csuse it kept hitting my arthritic middle knuckle.
