505 Gibbs

Hi.
I was wondering if any forum members would have any idea on muzzle velocity and muzzle energy on the load I am using. 130 grns ADI 2213SC (equivalent to 4831) and Woodleigh 600 grn Protective Points. I don't have access to a chronograph, but that load works a treat on Australian Buffalo.
Cheers. Baz.

Woodleigh says that 121 grains of your powder (ADI's H4831SC/AR2213SC) with F215 primer, Bertram brass,
600-gr PP SN
in a 24"-barreled .505 Gibbs: 2125 fps.

They say that Norma loads that bullet in the PH line for .505 Gibbs: 2100 fps advertised.

You must surely be breaking the 2200 fps barrier.

And you say the buffalo die well from that?

I’d like to bring my 505 next time on a Buff cull over yonder. The 458 Lott worked great but I bet the 505 works even better......

I would have to agree with doing over 2200 fps, and a guy on another forum said the same, he says 6500 ft lb of muzzle energy. One thing I can say, is that it Absolutely flattens Buffalo.

Quickload says 2207 fps.

If so, then with BC = 0.360 and MV of 2207 fps
to stay within the impact velocity window of 1800 to 2200 fps with the .505/600-gr PP SN:

3-yard velocity = 2200.3 fps
4-yard velocity = 2198.0 fps
190-yard velocity = 1804.6 fps
195-yard velocity = 1794.7 fps

Safe bet, with proper shot placement: Buffalo in range window of 4 yards to 190 yards.

A bloke on Australia's biggest guns forum has a 500 Nitro Double and a 460 Wby. He said while he loves his double when it comes to killing power on buffalo the 460 is a cleat winner.

JohnS who used to post on AR a real lot has one of his Echol's Legends in 375 Wby. The reason he chose the 375 Wby was after seeing on two trips the 375 AI and standard 375 H&H in side by side action. It is interesting that Saeed's loads in 375/404s for several years have been at the 375 Wby velocity area.

Mike, I had a 460 Weatherby for 30 years, also a 500 3inch nitro express, and I would have to say that the 505, with the loads I'm using, is just as devastating as the 460.

Those loads would be going faster than 500 Double loads though.

If you loaded the 505 right up that would be something, might recoil a bit

I load 140 grains of Retumbo under both the 600gr Woodleigh protected point soft point and solid, I use it to take up the monstrous case volume, the loads run an easy and low pressure 2155-2170 fps, a nice shooting, accurate, and what I believe would be very effective on all manner of game worldwide.

Well your right up there with 130 grs, some would condem such a load, but if its working and no pressure signs, then you have a winner, be sure and pick up your teeth before you leave the gun club or bush..

Baz505

Ray, I do understand that some would think that the loads I'm using are a bit heavy duty, on man and beast alike, but to me, that is the reason you buy a big bore rifle, to extract the most out of it and for it to be still manageable recoil wise. I find it amusing that guys say that they own a big bore, and yet use extremely mild loads in them and brag about owning and shooting big rifles.

I worked up to 148gr of AR2225 (RETUMBO) with 6000gr PP , chrono read 2378fps.
Recoil was ridiculous, 150gr and speed jumped another 100fps, which is where I stopped.
Have since sold that rifle, even with a 1lb mercury recoil reducer it only weighed 9lbs, recoil was bothersome even while standing with shooting sticks.
I certainly wouldn't have wanted a scope on that rifle.

RE25 & RETUMBO gave me the best performance, 2213 and 2217 (H1000) were better than 2209 (H4350).

Cheers.

I have always found the 505 to be the most desirable of all calibres although I have never owned one. If I did it would have to be the right rifle and that does not mean a CZ based rifle.

For practical purposes a Mark V 460 takes a lot beating. No feeding issues with the centreline feed and with the brake you can use them for any shooting. Even with the old Pendleton Dekicker they were quite good. They do 2500 f/s with a 500 grainer in a walk.

Mike , on the 460 Weatherby, I had one for 30 years, and loved it.

You bet 416, and 146 grains of H-4831 will power either 600gr Woodleigh to a full 2450 fps, I did just that to test my stock, bedding, crossbolt relation, all is good, this rifle broke the cams in two 1.5-5 leupolds so loaded, plus, I believe the 600 grain Woodleighs will perform better at 2150 ish fps instead of ran full balls to the wall.
Just as well, my 505 will be used for shooting couch sized animals at 30 yards or less, it doesn't need a scope anyway for my purposes.

Baz,
I've seen you shoot big bores. That sounds like a mild load to me! Couldn't be any worse than eating barbequed Jalapenos! HEH HEH HEH.

Do a Google search and check out Ryan Breedings articles in two different gun mags on the 505 as they contain some HOT load data. I use it in my 505 with Jamison Brass and 600gr. Woodleighs both PP and Solids. I get 2650 with no signs of pressure. I wouldn't use it for a hunting load on any dangerous game because of slow follow up shots and exceeding the impact velocity of the PP Woodleighs. However, it clearly shows what the 505 is capable of with modern components. Great cartridge!

Love my Dumoulin .505. Have carried it for 30 yrs and it has saved my life four times now. 600 grainers - North Fork CNS's at 2140 fps are the ideal load for everything except bull elephant. With South African powders a mixed duplex load of 60 grains S 385 and 60 grains S 365 gives me this velocity from my rifles 25.5 inch barrel.

Do you stack one powder on the other. Thinking about that and the 505 capacity they would mix anyway.

Many years ago (1970s) I used to do a 50/50 mix of 4064 and 4350 for the 375 H&H.

Baz,
Your right when a caliber or rifle becomes nothing more than penis envy its usefulness is void...Too many big bores exist in the hands of folks that can't even start to make a good shot with them..Ive shot them all and my personal best, meaning I can shoot it as well as a 222 Rem is the 404, 416...I tried the others and I could shoot them all, but I had to stop and concentrate on the fact that it wasn't going to kill me, so I shot all my buff with the 40 calibers and a 470 double with a 500 gr. bullet at 2100 FPS, not a max load..Butch shot my 470 at 2245 FPS and it was an attention getter!! My 500 gr. bullet at 2100 hammered buffalo,so I opted to skip the punishment. Just my opine, and the limit of my ability I suppose.

That will be a stout kick. You will probably get about 2150 to 2200 fps with that, which will be plenty good enough for anything. I shot my first 3 water buff with a similar load, but using 2209, and it is very effective. However slow burning powders kick a fair bit. Now-days I use around 105 to 108gn AR2208 with a foam filler to take up the airspace. It gives me around 2200 fps and is lighter on recoil.

Great honesty, there, I believe. I think the problem is compounded by most modern hunters spending much more time shooting at targets than critters.

I suspect the old-time elephant hunters probably had a look at the sights on their rifles but rarely shot at targets. When seven yards from tembo, recoil would have been much less of a problem.

I use 105g H4895 in my 500 Jeffery (smaller case) no filler gets a 570g up to about 2400 fps. Kicks less than an IMR4350 load to get to the same velocity. Both loads will clear your sinuses though
