Anyone used PP 1200-r to load Grendel? More inside.

[Ludeconduct]

It seems that the 6.8 loaders are using it with no issues and I can't find any info on it being used on Grendel. I cannot find the burn rate for it but from reloading sites info about it being faster or slower than another powder it seems to fall between a lot of the common powders that are used to load this round. From the posted 223 data (which is all they give on this powder) the manufacturer's data shows high speeds for relatively low charges with it. I called them and asked about any data for the 6.5 and they quickly told me there was no data for anything except 223.

Alliant shows loads for the .222, .223, 22-250, 30-30, and 7.62x39. Note that the bore capacities and operating pressures in this collection of cartridges spans that of the Grendel.

Alliant 1200R is a ball powder very similar to Reloder 10X, an extruded powder. 1200R reportedly meters better for progressive reloading.

Reloder 10X seems to be rarely used in the Grendel.

Haven't heard of anyone trying 1200R in the Grendel.

It is a very good metering powder in a progressive setup. I have a good bit of this and due to lack of powder options I may have to start low and work up and see what it will do. It seems fast with relatively low charges on the 223 and is very dense so you would be hard to put enough to have a compressed load. Maybe this is the Unicorn powder I have been hunting.

Ok I found the other calibers it is being used with on Alliant's site. I was looking with product description. It does seem to be fast for low charges though. Look at this 30-30 chart.

We thought Reloader 10X would be the 'Unicorn' powder as well. It is dangerous in the Grendel with bullets over about 85 grains.

The pressures will go up dramatically when you reduce the neck size and you are reducing the neck size significantly if you go from a 6.8 or .30 caliber down to a 6.5.

If you can't find this powder listed in any of the numerous loading manuals for the Grendel, you best stay away from it.

Makes sense. This is a new powder so I guess it's a wait and see game with alliant to see if they come out with a load for it.

Hornady and Nosler both have published data for their 100gr bullets with 10X.
Pretty sure they would not publish load data if it was indeed "Dangerous".

Here is my quote. "If you can't find this powder listed in any of the numerous loading manuals for the Grendel, you best stay away from it."

You found it listed so no problem.

My warning was for powders that are not listed. Like Reloader 10X when it first came out.

Alliant's response on this powder.

Charles, this powder will not work with the 6.5Grendal the bullets are too heavy for the case capacity.

Yet they have data for the 7.62 x 39 with 1200-R with 123gr bullets. That's a pretty poor excuse for an explanation of why this powder is not suited for the Grendel if you ask me.

[JASmith]

The 90 gr 6.5 TNT has almost the same (0.183 vs 0.184) sectional density as the 123 gr 7.62x39 bullet. The case capacities are almost identical

The 170 gr 30-30 bullet has a greater (0.256 vs 0.246) sectional density than the 120 gr 6.5 mm bullet. The 30-30 has a skosh more than 44 gr H20 to the approx 35 gr for the Grendel.

In other words, while we respect caution and the suggestion to not use the powder in the Grendel may be sound advice, using faulty logic to support the blow-off tests patience.

It would be interesting to see how the fellow who made that statement responds to these comparisons. The fellow may have been clueless about the case volume of the Grendel and assumed it was .260 Rem or larger.

[Ludeconduct]

Raises my curiousity. And why do you find powder companies skipping the 123 amax in their test ?

[JASmith]

In the case of Alliant, the 123 AMax is not one of theirs.

Actually you said "It is dangerous in the Grendel with bullets over about 85 grains."

That's a far cry from "if you can't find the powder listed..."
