.577 NE 3" Loads

I have a .577 NE rifle coming in shortly, and I am just now starting to load up some rounds. I am looking for a load that will produce about 2000 FPS at the muzzle using 750 grain Woodleigh bullets and Federal 215 primers. I am not interested in using dacron fillers, etc., and am looking for a powder that will more or less fill up the case. Thus far, I have loaded 20 rounds using 150 grains of Reloader 22, which, on paper , produces the desired result. If anyone could suggest some alternative loads, (maybe using Accurate 4350, etc.), I would be grateful. Thanks in advance for any advice. Cheers. Chip.

Ross's data will get you 1900, maybe -- Larry at superior has the data richard hill and I came up with..

fillers are a non-issue - USE THEM -

rel22 is a bit slow

There is lots of info on the internet. Here's some.

Also Quick Loads internal ballistic software has lots of capability. The .577 NE comes in more than one length. You need to be precise. At a cursory glance I don't see the 750 grain bullet listed there but I will look further.

Word of caution. Some websites have extremely erroneous loading data. Turn around and run the other way from them.

Here's some load data from this websites loading pages. Check your length.

Maybe check your bore too. The .577 is listed as having a .584 - .585 bore ???

That's the old black powder cartridge.
____________________________________________

The A-Square load manual has 3 powder recommendations: H-4831, IMR-7878 and RL-15. These fill the case quite a bit and vary from 132 grains to 167 grains. Velocities are from 1,889 to 2,128 and pressures 21,000 to 34,000 psi.

Starting load for H-4831 is 153 grains; for IMR-7828 160 grains and RL-15 132 grains. These loads have been checked with a piezo transducer. Allowable pressure average 35,588 psi. Max ind 40,900.

A roll crimp 0.008" is recommended as well as a long drop tube. Powder compression is necessary for consistent ignition.

Case capacity is said to be 185 grains.

You should check your rifle for proof marks and regulated for 100 grains of cordite with 750 grain bullet if it is a doubles rifle.

wetbbe: thanks for that information. My .577NE is of new manufacture from Heym in Germany. It is chambered for the 3" brass. Thus far, I am relying on 3 different sources of information. 1). Graeme Wright's "Shooting the British Double Rifle", 2).Pierre Van Walt's "African Dangerous Game Cartridges", and 3). Art Alphin's "Any Shot You Want" Mention is made, in these publications, of Reloader 22, H-4831, IMR-7828, IMR-4831, IMR-4350, IMR-4007SSC, and AR-2213SC. All of these loads are referred to in conjunction with 750 grain Woodleigh bullets and would not require any fillers. I was wondering about what other powders and weights might be appropriate. Thanks for your help. Chip.

Chip:

Fabulous. What a fantastic firearm.

I knew Art Alphin back in the old days briefly. He was rock solid and way ahead of the pack in intelligence and knowledge. You can put your chips on him.

I was always a great fan and aficionado of Mauser. I collected many of their rifles dating all over past to last.

Heym dates back to the 1870's as does Mauser. Mauser folded much to my great consternation and disappointment.

Heym seems to prosper manufacturing their own brand of quality and I am laboring to understand the whys and wherefores of these two excellent manufacturers.

I would like to hear more about your experiences if you whack a rhino, elephant or hippo.
