I have a Sharps Replica that I will be using your 530 Grain I bought on GB.
What load would you suggest, it will be using Smokeless Pwdr?
I have an assortment of Powders, having had two Trapdoors I let go to get the Sharps.
I'm a Highpower Shooter during the Summer Months, so I have access to a 600 yard Range with pits.
I would like to be able to shoot 600 yards, as it has a Vernier Sight.
Thx,
barman54

Take a look online regarding using Accurate Arms 5744 powder. I've used it in .45-70, .38-55 and .50-70 with good results. Western Powders and Ammunition Loading Guide is good reference. Shooting Buffalo Rifles of the Old West, by Mike Venturino, take a look. Also, look here: shilohrifle.com/forumsHope this helps get ya started... |

Thx for your Reply
I have 5744, RE7, 3031, Both 4198's, 2015, etc.
Just did not want to shoot 50 rds to find a recipe ?
I have the Lyman Cast BIG Book, just does not have a 530 Pt Bullet, has a 500, 525, 535,540, and the Consolidated 45/70 Caliber book
Had some 502, and some 526 RN used 5744 used, 25.0, and 26.5 respectively, left some Powder in the bore, bought them from a fellow Club Member.
Just seeing if any one had good results with a certain charge?
Thx again.

The 5744 load I've used since the 1980's in my Shiloh (Farmingdale, NY) military carbine in .45-70 has been 28.5 grs of 5744, 350-405 gr cast bullets. Might be a bit too much powder with a 530 gr cast bullet? Start with minimum loads and work up carefully. I also use this load in a .45-70 Peabody carbine. See Peabody rifle/carbine Post elsewhere in this Forum. As with any load information: it works in my carbine(s), use based on your own decision, k'. With the carbines I'm not shooting beyond 150-200 yards maximum. This load has harvested a few caribou in it's day, when I was in Alaska years ago. I'd recollect my longest shot at a caribou was 'bout 140 yards. In .50-70 I use 25.0 grs 5744 behind a 420-450 gr cast bullets. I'd speculate you could use the 525 gr listed load for your 530 gr cast bullets without any difficulties. If concerned, begin with the reloading manual Minimum Charge, then work with any increases in powder weight accordingly. As we all know, each rifle will decide what loads work best out of their barrel. Mostly a matter of 'road testing' various loads to see how it will perform? Again, there's a heap of information on loading the .45-70 with 5744 on line. This is from pdf.textfiles.com/manuals/FIREARMS/2003guide.pdf (L) 530 Bullet POST OAL = 2.950" b5744 26.6 1251 29.5 1360 |

Good evening
I agree with the use of 5744. Works great for low powered up to medium crushing smokeless loads. Start low and work up. But remember it has the potential to go beyond the strength of a BP rifles capacity. It will give near "magnum" power.
When we started loading for a 50-95 1876 replica I called then Accurate Arms and talked to a very helpful Tech. man. They had never worked up any info with 5744 in the 50-95 and wanted to help and add the caliber to their data base. They gave me some basic info based on case capacity, bullet weight & length, primer...
Gave me a very mild low starting load and suggested the amount to use as a step ladder trial.
So what I did was fire 5 rounds with my cast 350 slug using as much goex 3F 9with a cereal box wad0 as the case could hold to get 5 shots over our Chrono and have a 50 yard accuracy baseline. I think 84 grains 3F was the max.
The 3F load shot a under 2" cloverleaf off cross sticks. Refired it at 100 yards and got under 2.5 inches. Velocity was 1465 fps.
So I stated loading 3 rounds at a time with 5744 shot over our chrono at 50 yards. When the load reached my 3F velocity it was just 1/4 inch wider in diameter than the 3F load. Refired it at 100 and it was just over 2.5 inches.
Then tried the next step up with 5744 and group expanded. Tried 3 more same results at 50 yds. Loaded 5 more with the better lower load and again got the same hair over 2.5 inches at 100 yards. Repeated and got the same results.
Called Accurate and told them the long story and they were very happy with the info.
So my advice... Give 3F a whirl. you are very likely to discover real fast the accuracy potential of that slug. Then try to beat it with any smokeless powder. I have done this simple system with most our BP cartridge rifles. Usually there is no smokeless load that will beat BP. Some may tie but none have ever beat our BP best load.

One load that I use and has been in use longer than I have is 21gn 2400 in the 45-70 case with about any bullet weight. I use this load in Sharps and Trapdoor rifles. I do use a packing popcorn filler with this load. This is one of the loads I used last year for the Billy Dixon 1500 yard steel buffalo shoot. Maybe not the best for extreme range use but served well at the Billy Dixon shoot. I was shooting a 500gn paper patch bullet because my 1/20" twist rate will not stabilize a longer bullet like the Postell at ranges past about 500 yards. The faster 1/18" and faster twist rates will handle the longer bullets well past 1000 yards.

I have 2400, and Packing Material suggested.
How long do you make it between the Powder and the Bullet, to where it is Compressed, I understand I can roll it to make it to fit the case?
Also, on crimping, when I crimp to 2.950 OAL, there is Lube Rings exposed, never loaded a bullet this long, is that normal?
Thx,

Using any filler the space between bullet base and powder has to be completely filled. Amount of compression of the filler is not critical. As long as there is some compression of the filler you can be positive the empty space is filled.
It is perfectly normal with some bullet designs to have lube grooves past the case mouth outside the case. It depends on bullet style and chamber throating. I prefer to always have cast bullets at least touch the lands and to do this depending on the bullet design often requires that one or more lube grooves are outside the case. If the bullet design has sufficient lube volume inside the case the lube grooved outside the case can be left empty.
