Default Accurate Arms: XMP5744 Data (and others)

In another thread there was a mention of Accurate Powders including XMP5744 or simply 5744 as it seems to be called now. I inquired of Accurate Powder's techs as to the proper .30 Carbine reloading data to use. They furnished me the following which I simply copy pasted to this thread verbatim. The formatting is as clear as I can clean it up. The data for 5744, 4100, and No. 9 is below:

Caliber: .30 Carbine. (M1)
Barrel length: 17”


Powder: Accurate -- 5744.

Bullet weight: 110 grains.
Start load: 13.5 grains (1700 - 1800 ft/p/sec)
Maximum load: 15.0 grains (1900 – 2000 ft/p/sec) Full case

Powder: Accurate -- 4100. (1st Choice)

Bullet weight: 90 grains.
Start load: 14.0grains (2100 – 2200 ft/p/sec)
Maximum load: 16.0 grains (2300 – 2400 ft/p/sec).

Bullet weight: 100 grains.
Start load: 14.0grains (2000 – 2100 ft/p/sec)
Maximum load: 15.5 grains (2200 – 2300 ft/p/sec).

Bullet weight: 110 grains.
Start load: 13.0 grains (1900 - 2000 ft/p/sec)
Maximum load: 15.0 grains (2100 – 2200 ft/p/sec)

Bullet weight: 125-127 grains.
Start load: 11.0 grains (1425 - 1525 ft/p/sec)
Maximum load: 13.0 grains (1700 – 1800 ft/p/sec)

Powder: Accurate – No 9.

Bullet weight: 90 grains.
Start load: 12.0grains (2000 – 2100 ft/p/sec)
Maximum load: 14.0 grains (2200 – 2300 ft/p/sec).

Bullet weight: 100 grains.
Start load: 11.3 grains (1900 – 2000 ft/p/sec)
Maximum load: 13.5 grains (2100 – 2200 ft/p/sec).

Bullet weight: 110 grains.
Start load: 11.0 grains (1800 - 1900 ft/p/sec)
Maximum load: 13.0 grains (2000 – 2100 ft/p/sec)

Bullet weight: 120 grains.
Start load: 10.0 grains (1525 - 1625 ft/p/sec)
Maximum load: 12.3 grains (1800 – 1900 ft/p/sec)

Bullet weight: 125-127 grains.
Start load: 9.7 grains (1425 - 1525 ft/p/sec)
Maximum load: 11.5 grains (1700 – 1800 ft/p/sec)

NOTES:

It’ important to note that SAFETY is our prime concern therefore we strongly recommend.

1. TO ALWAYS BEGIN LOADING AT THE RECOMMENDED MINIMUM “START” LOAD and develop loads in 2% increments towards the MAXIMUM load.

2. If at all possible, measure the velocity and correlate with our data.

Steve, did they give you any primer data as to which type they used??

No case or primer data. I copy pasted exactly what I received. My old computer could not open their Adobe.pdf website data system for all reloading all calibers and I asked for the .30 Carbine info only. If you access their website and get the entire .pdf it may have more info.

That said, I have always mixed cases and used what ever primers I can find as long as they were standard small rifle. WSR and CCI small rifle by choice. I have never detected a difference between one case type and another or one primer or another as far as reloading the .30 Carbine goes. When I would shoot factory ammo to start accumulating 500 cases per batch, whatever new ammo I shot went into the batch.

I do not claim that to be the "best" practice, but if you shoot a lot it makes things simpler. When the rims are too chewed up to function correctly, the cases get pitched as a batch. Before then, perhaps 2 or 3 cases will split from the mouth rearward which is just brass hardening from resizing. The rims get chewed up before the primer pockets get loose. Likewise with excessive stretching, the rims go first.

Default Steve: You might check and change the extractor

Both my carbines NEVER mark or cut the rims. They actually leave no mark whatsoever. Perhaps someone has shot a lot of steel cased ammo and distorted the extractor? My brass never splits either. I don't even track number of loads with the carbine, I simply trim when needed, which is infrequently.

Thank you for the helpful reloading advice. Steel cases ammo is not used and no extractors are used, worn, or distorted. The extractors get replaced when I get a new carbine along with all the other small parts in the bolt. With any number of carbines over the years, by 7-8-9-10 reloadings, the rims are a dinged, dented, scruffed mess. 2 or 3 out of a 500 batch spliting lengthwise is a regular occurence, but with no pattern. Infrequent trimming is not my practice if you have read the top page sticky here. I trim them every reloading to make very sure the ones that decide to get long this reloading don't jamb my bolt half locked the next firing. Properly trimming everyone is easier and faster than measuring everyone and trimming some.

Steve, thanks for the additional powder data.. I'll try getting the pdf and if anything additional is available I'll add to this posting...
First look, no .30 Carbine in the load data pdf

Thanks. Some day when I am rich I need a faster computer. Odd, though, no Carbine data in the .pdf manual. Good thing I asked for .30 Carbine data specifically. The techs at Accurate are very very helpful with consumers and questions.

They do have a good looking powder in the 4100. I would be curious as to the pressure to achieve those 110FMJ velocities.
