Anyone have a velocity for 335 gr WFNGC using 16.5 gr Alliant 2400 in Redhawk 45 colt
5 1/2" barrel?

1062 fps - Quickload, assuming a .780" bullet and a COL of 1.580. The Lee .750 bullet is .750 so I added .030".

If you tell me your bullet length and cartridge overall length (assemble a dummy round) I can give you a more exact figure. Otherwise that should do it.

Thanks Frank,
Bullet is .850 and COL is 1.665. Don't know if Quickload asks for it, but WLP primers.
Curious now on how much it'll change with the bigger bullet and COL.
Does it give pressure also?
Thanks again.

1049 fps

25735 psi


Note: I think you are around max pressure at 16.5 grains. The Hornady load when put into quick load shows 25697 for their 300 XTP and 18.0 grains. So use caution and work up.

Also as a reminder, these loads are for Ruger or TC only.

I've got a question. When you take one of your slugs and drop it into the cylinder, do they stay in or fall through.

[steely]

Frank,
They stay in cylinder about flush from exiting.

Frank, I know im up there in the pressure dept.
Can you check a different powder for that bullet?
20.5 gr H110. Everything else is same as before.

either one of those load are relitively mild in a large framed ruger. Ive shot loads that make those look like plinking loads in rugers back in my younger days.

'Relatively mild' might be an understatement. According to Quickload, 20.5 grains is 88.7% load density. I think you need to be > 90% or you might get a stuck bullet in the barrel, right? But I would verify any load above with a reloading manual.

steely,
Here is what I come up with:

335 grn
1.665 COL
.850 BL
20.5 grns H110
1023 fps
22603 psi

Lloyd, what loads would you recommend?

[steely]

I actually got the 20.5 H110 load from the Hodgdon manual. Although it is the starting load.
A lot less pressure then the 2400 load.

[dubber123]

How thick are the chambers? Assuming, (theres a good word), equal thickness, material and heat treat, max pressure should be the same. For example, if your Redhawk has the same thickness chambers as say, a S&W .44 mag, I would feel comfy running up to SAAMI max .44 mag pressures.

Redhawks are not Colt SAA copies. They are tanks. Safety is good, but you need to add some reason occasionally. Buffalo Bores factory 325 gr, load is advertised at 1,325 fps.

My most accurate load with the 335 gr boolit out of my old model Vaquero is 21.5 gr of 296 and the Fed 150 primer.
I have worked higher but groups open past 21.5 gr. Also if I go lower.

Dubber123, the Redhawk cylinder is much different than that of the S&W. The S&W has the bolt notch directly over the chambers, so the cylinder wall is extremely thin there--it's always the point of rupture when the gun blows. The Redhawk has the bolt notch offset to the side in a thicker part of the cylinder. Also, I don't remember the numbers, but the Redhawk cylinder is physically larger than that of the N Frame S&W. The Redhawk .45 Colt cylinder is significantly beefier and better designed (the bolt notch location) than the S&W .44 Mag. I don't remember the issue, but Brian Pearce wrote an article in Handloader on .45 Colt loads, and mentioned that the .45 Redhawk will handle over 35,000 psi. John Linebaugh has written some excellent stuff here: http://www.customsixguns.com/writings.htm

My heavy load in my .45 Redhawk is a custom 320 grain bullet over 22.0 grains over 296 with a CCI mag primer. I have no doubt that my Redhawk will take a lot more punishment, but I also have no doubt that it'll take a steady diet of the above load over the long term with no problems.

I think you just said the same thing I did...[smilie=1: If a Smith .44 will take 35K, I figured a .45 Redhawk would at least take the same in stride.:-D
