Jumping crimp

[Scott Tschirhart]

Yesterday I was shooting some old factory .454 Hornady 300 grain factory ammo.

You know you have something that is just not right when the first four rounds make the fifth jump crimp!! Fortunately I had a brass drift and a small brass hammer that I used to re-seat the bullet.

Scott, you are a far tougher guy than I am burning up Casull rounds. I doff the Stetson -- and I'm glad you had that hammer and drift.

No comment on the ammo except to say 300gr 454 is a lot of power. Since the 454 topic is on the table, I have studied the ballistic tables and convinced myself there is no advantage with the 460. The 454 seems to be seriously under appreciated as hand cannons go. It is incredibly powerful in a normal size handgun. if you consider something like a Redhawk normal as opposed to an almost comical X-Frame.

Probably to be honest for a minute, anything beyond 44mag is more a net negative than a plus for me. Within that upfront, the 454 revolvers are sized right and seem like they really push the limits for human capability even if lacking the extreme bragging rights of the XFarme options. One can down load the 460&500 but the gun is too big. It seems to me a 454 with 250 xtp handloads would provide a nice step up from 45LC or 44mag.

My thinking on a cold winter morning.

fourbore ... that is exactly why I liked the Freedom Arms 454 and the Linebaugh guns. They weren't any larger than the Super Blackhawk. And my old FA 454 with fixed sights was about like the standard Blackhawk. I could carry it all day and it didn't need a wheel on the front of the barrel.

I did not care for these loads and I’m more than happy to top out with a .45 Colt and a 270 SAA over 13 grains of HS-6. Remarkably accurate and consistent without punishing recoil.

I wonder how many bullets jump crimp and are never noticed because the bullet doesn't get past the end of the cylinder. My buddy had one jump crimp in his 38 Special, and only noticed because it tied the gun up. Didn't phase him, and he kept shooting soon as it was cleared.

Good reminder that I should check all of my loads. I've substituted bullets and not checked.

Glad you had the tools handy to remedy it.

I have a 454 SRH 7.5" and 460 X frame 8.375". 454 is a better all around for anything revolver.

But the 460 has it's place. It will tack on several hundred fps for 200 gr bullets for longer ranges. And once you get over about 325 grain bullets, the 460 will blow the doors off a 454.

If I could only have one of the two, it would be the 454. But my scoped X frame is actually more pleasant to shoot that my SRH, as long as I am wearing ear plugs AND muffs.

But my S&W 25 six inch is better than both.

In short, you just need one of each.

While hunting with my FA83 .454, I will always empty the cylinder of the extra rounds, and reload 5 fresh, to fully inspect the unfired rounds. Last thing you need is having a bullet jump it’s crimp, in the middle of a sporty situation!
