Anyone have any data for CFE Pistol?

Post by DHKnecht » 08 Jun 2014, 16:50

Ramshot True Blue is next to impossible to find, as are most of the other powders with data. However, I was able to pick up a couple of pounds of the new CFE Pistol powder from Hodgdon. It is used in everything from .380 AP, 9mm, .40 S&W to .45 AP. Hodgdon shows its burn rate in the chart below (The number on the left is the powders ranking on the list, with the lower number being the faster powder, but there is no set increment in burn speed between the numbers). In any event, it looks like CFE Pistol burns somewhere between HS-6 and HS-7. So, has anyone tried this in the 5.7x28mm cartridge yet? If so, what were your charges and what were the results?

29 Winchester 231
40 Ramshot True Blue
41 Accurate Arms No. 5
42 Hodgdon HS-6
43 Winchester AutoComp
44 Hodgdon CFE Pistol
45 Ramshot Silhouette
46 VihtaVuori 3N37
47 VihtaVuori N350
48 Hodgdon HS-7
49 VihtaVuori 3N38
50 Alliant Blue Dot
51 Accurate Arms No. 7

Using a powder's burn rate is not a good criteria to use, by itself, to load a cartridge. I don't know enough about interior ballistics to offer an alternative, but that very question about using True Blue for use with a .17 Hornet load came up. I asked Hornady if True Blue would be OK for .17HH because it's close to AA1680 in burn rate. (AA1680 is recommended for .17HH, but apparently not available). Hornady replied that TB wasn't suitable....

I suggest you call CFE and ask them if they have any data or could suggest a starting load.

By itself, no, but its certainly a valid question, and seeing as hodgedon doesn't have any data for this round, I doubt they're going to offer any for CFE Pistol... I'm also curious if anyones worked anything up yet.

CFE Pistol in 5.7?

Post by Wagonbacker9 » 17 Jul 2014, 10:29

Like most, I'm putting my hands on whatever I can find, and I was lucky enough to acquire a pound of CFE pistol. I see NO one out there in internet land that has attempted it in 5.7x28, and though the burn rate is in range, I have no idea if it would be an appropriate powder in this cartridge.

Anyone care to offer advice?

I have 25gr and 40 gr vmaxes available as well as barnes 36gr hollow points.

Merged w/original thread.
I'd assume a lack of response here means no one has tried it & no one wants to steer you wrong.

Have you contacted Hodgdon? I checked their website but they don't even have the 5.7 listed on their data pages.

I contacted Hodgdon.

This is what they said:

We have no data of any kind for this cartridge. FN does not wish to participate in the American standards for ammunition (SAAMI) so there is no standard for pressure, velocity, dimension nor is there reference ammo to calibrate transducers and barrels. There have also been several instances of ruptured cases resulting in damaged firearms and a couple of injured shooters resulting from the lack of standardized ammo. Until such time that FN joins SAAMI and works with US Ammo standards, you will not see anything in the way of data from reliable sources.

I resent that! If I say my loads are reliable, they are! :laugh:

Thanks DoubleJ

Funny how the holy grail of 5.7 powders, HS-7, happens to also be a Hodgdon product. I also sent them an email about bringing it back, they didn't respond...

Maybe someone with QuickLoad could run the numbers on CFE? I think the idea of copper fouling in my 9mm is silly, but it's totally plausible if you're shooting light stuff in your FSN or 90. I've also found CFE to be cleaner and quieter through my Tirant than AA7, while I've found Longshot to be as loud as a deck gun on a battleship through my FSN. Another powder choice would be nice.

Once my brass is finalized I will start the process for SAMMI certification.

Longshot is definitely the louder than any powder I have loaded in fsn BUT it is the most reliable gun powder I have ever used for this cartridge. I just got done loading 500 of My 2000 round case of SS198 with Longshot and I have no complaints at all.

Apologies, I thought this thread was on another forum.

So I guess that makes Western "unreliable"?

I'd take it on trying it myself, but the only thing I could even imagine for a starting point would be to use an equivalent ratio of starting load for AA5 or AA7 based off a 9mm case, and that sounds FAR too risky to me, seeing as I have only a fundamental understanding about what makes a powder suitable or not.

I've been using Longshot in my 500Mag as well, and the concussion from the comp is retarded, although the velocities are modest. Not sure why we needed Autocomp when that stuff was already on the market.

I would have no issues with experimenting with that powder after comparing its posted loads to other posted loads from powders already tried and tested that are used in the FSN. I have been looking for some to test with and have not found any yet.

I will put this out there as an option for anyone who has this powder or access to it, I will trade you 1 lb of True Blue or Hodgdons Longshot powder for 1 lb of CFE pistol. Send me a PM if you are interested. If I find some or someone trades me for some, I will test it and post the loads for all.

Shipping being difficult, if you want to educate me on how you'd go about development I'd take it on.

Heres a quick table, I used 9mm because theres a full compliment of data, and 380 because its also a tiny sensitive case:

| 40gr vmax 5.7x28 | 115 JHP 9mm | 90Gr XTP 380Auto
Longshot | 5.2-6.0 (my load) | 5.0-6.0 | ~4.9 (estimated, unpublished)
AA5 | 5.1-5.7 | 5.4-6.3 | 4.3-4.8
AA7 | 6.1-6.8 | 6.4-7.5 | 5.9-6.5
CFE | ??????? | 4.9-5.4 | 3.7-4.2

So using the AA5 data (closest burn rate), I get a 4.4-5.0 range... but change powders and the ratios don't come out anywhere near close.

I ran a bunch of calculations and comparative data and based on that it should be able to be taken up to 5.4gr.. But I personally would start start it at 4.0gr shooting 5 rounds and increasing it in .1gr increments. Alot of the cross calculations came close to the 115gr 9mm LRN data. But to be on the safe side I would start it at the 4.0gr...

If anyone decides to try based on this, Please be safe, DOUBLE check your loads, cases, and seating depth. It would be best to use factory fresh cases.

I'll load up a set, no idea when my next trip to the range will be though. I should have just enough 40gr vmaxes left to cover that range. I'll probably load up some 25gr pills as well. I'm thinking a reasonable start load for that may be about 4.5? I personally see no reason to go over 5.4 max as that round will already be smoking.
I'll bring the chrono with to see what they run.

I have CFE Pistol powder, but currently use Titegroup. I can run a load of CFE and see how it turns out. I use a magnetospeed with a rail mount for my testing.

Just for the record, some of us did try CFE, and it worked, I can post my data if anyone is interested.

Just for the second record, I spoke with Hodgdon about HS-7, and found that it was discontinued many years ago as it was expensive and inefficient to produce. Seems that we're the only ones that want it back, everyone else is happy with HS-6 and such, although I still see old load data where it trumps everything else, in several different calibers.
