Hodgdon Powder data.
Use this thread to post Hodgdon powder data.

Here is some info from my work with Longshot. Always start 1.0gr lower and work up in .2gr increments until you see pressure signs. (Waters' method):
Starline Brass, CCI 350 primers, 1.26" OAL. 10 shot avg. G20 85F and 5000ft elevation.

135gr Nosler 13.2gr LS - 1542fps
165 GSHP 10.4gr LS - 1356fps
180 GSHP 9.6gr LS - 1294fps
200 XTP 8.2gr LS - 1172fps

These are loads that I have worked up to and are under 37,500psi when I had them tested. I hope this helps!

Mr. MCNETT, I got my KKM[5 5/8"]Bbl and a 4lb jug of Longshot Horn 180 HAP bullets loaded 9.0 CCI350 Horn cases They click. Used a rear Protekor leather bag for a rest at 50 yrds 10 shots were sub pie plate easily {I'm still getting used to this g20} Several double touching holes.Empties kick about 15-20' at 4 0'clock. The KKM chamber leaves the fired cases nice and straight. No bulge to speak of I'm happy. Now; a g29?

Oh yeah the HAP recovered from soft rock free dirt about one third mushroomed sorry the measurements are elsewhere. Looks to be a great penatrator bullet.

Titegroup reloading info
Does anyone have any data for loading Hodgdon Titegroup with the lighter 10MM bullets? Their website only shows info for the 180 and 200 grain bullets.

Titegroup is one of my favorite powders in 9MM and .40 and I'd like to use it in the 10MM as well.

Hodgdon H108 - Has anybody tried this in 10mm?
It is a very fine 'ball' powder. It is supposed to be faster than H110, and I read somewhere that it was approximately the same as AA #9. With AA#9 you seem to get pretty good velocity, and you can't get too much powder in there to cause too much pressure.?.?.?.
Powder valley has 8lb H108 for $50....I bought it for 458 SOCOM, but it seems to be decent (and safe) for 10mm.
A 10mm casing will hold approximately 23.0 grains of H108 full to the rim.
I was able to fit about 18 grains of H108 behind a Rem 180 FMJ FP bullet. This was an extremely compressed load. The FMJ did not deform, but some bullets COL was springing back to ~1.270+
I was able to fit about 14 grains behind a 200XTP without deforming the bullet. Up to 16.5 grains would fit, but the HP was swaged nearly closed.

Looking at my notes back in May:

Both of these sessions, I didn't know about Waters' Head expansion measurements. All I know is that NONE of the brass had smileys!

I have recently re-visited this powder, and I have built, but not shot, up to 18.0 grains behind a Rem FMJ FN. I will report on these loads the next time I break out the chronograph.

Has anybody else played with this powder?

spongeman66 03-20-2004 23:03

Using the Waters' method these show similar or less head expansion than DoubleTap in MY gun.

12.9 HS-7 Lo=1209 Hi=1255 ES=46 A=1237 SD=18

Doesn't beat 800X, but not bad.
I did load workups from 10.2 grains. I do NOT recommend HS-7 for downloading. It doesn't seem to burn cleanly at the lower pressures. It leaves powder in the barrel and if you had a tight chamber you might have difficulty.

BTW, if anybody is interested:
17.0 grains of H108 behind a Rem 180 FMJ CCI-350s produce similar head expansion to DoubleTap. From a 5" 1911 produce 1308 FPS. This is an compressed load, and will deform 180 hollow points.

I just got back from shooting 180 gr XTP's over 9.6 gr of Long Shot through my G-20 with a stock length KKM barrel. This is now the most accurate full power load that I have shot with the G-20.

Most of you can shoot better than me, but for what it is worth, shooting off hand this load put 11 of a 20 round group inside a 3 inch circle at 60 feet. The balance of rounds were within a 7 inch circle on the same center. This is definitely a load to try in a G-20.

More HS-7 Data. I am a little disappointed at how dirty it is, and the low velocities I got.

HS-7 burns cleaner with Magnum primers. Bass Pro didn't have a full 1K of Federal 155s, so I bought 1K of CCI-350s.

I would choose 12.0 because 12.2 had a velocity drop, and 12.4 had a slight smiley.

I was running out of powder, so I didn't get to shoot very many rounds with 200XTPs:

Longshot works for me!
I just started using Longshot for my G20 and S&W 610. I realy like the powder and it's very clean for me. In the S&W 610 I'm using 10.0 gr Longshot under a 180gr JHP and have no signs of pressure. That is one of the things I have noticed about Longhshot is that it runs lower pressure than most other powders at higher velocities. I'm loading 44mag rounds with it now and think it's great. Going to place an order for an 8lb. jug this week for it at, possibly 2.

G-20er 08-28-2004 13:53

Learned something very interesting today while using LongShot Powder. For starters it doesn't even come close to Mikes DoubleTap 200gr. XTP loads. See other post for details.

Also I learned that I can actually get the same velocity out of 8.2 grains as I can get out of 9 grains. Note: 9 grains is not worth the extra pressure. Check out 8.5 grains...the velocity actually is lower than the 8.2 grain load. What the heck over? Keep an eye on the ES also. Looks like I'll keep the 8.2 grain load. I tested it twice because I couldn't believe that the 8.5 was actually slower than the 8.2

G-20 with standard length KKM barrel and 22 pound recoil spring with tungsten guide rod. All bullets fired were 200 grain XTP with a OAL of 1.270. New Starline brass and CCI 350 Mag primers. Note: all brass still flew 10-12 feet to the right. Wish I would have ordered the 24 pound spring.

By looking at the E.S. this load prefers the 1.260 length.

Below is at 9 grains with slight change in OAL:

1) 1183.0 5.6
2) 1156.0 -21.4

Low: 1121.0
E.S.: 89.0
Ave.: 1172.6
S.D.: 32.6
95%: 41.0

As you can see the E.S. got worse with this load as the bullet was seated closer to top of powder charge. Do not recommend this load due to no real advantage in velocity over the 8.2 grain load.

BuffaloBo 09-05-2004 17:51


Didn't our esteemed colleague Clark over at the "Reloading forum" have some warnings about blowing out a case using Longshot? I thought I read his words in a post of how just a slight variance in charge caused a case blowout? Would Longshot be the Hodgdon powder of choice in 10mm? I ask because I have zero experience using Hodgdon pistol powders.:)

G-20er 09-05-2004 23:25

I didn't have any signs of over pressure up to 9 grain with the 200 gr. XTP. So I don't think there is a problem to go over max listed. However, I don't see any reason to either. The more powder I added the velocity never really went up. This speed of powder with the heavy 200gr. bullets is at it's limit at 1170-1180 fps out of the standard length barrel.

My experience is that I need to go to a slightly slower burning powder to get a little more velocity. Using max loads of LongShot with the 200gr XTP I still had about .090 gap between top of powder and base of bullet which tells me I can and should go with a slower powder (takes up more room). I prefer 98%-100% load density.

My next powder to try for this 200gr XTP bullet is 13-13.5 gr. of AA#9. I hear it meters well and load density should be perfect. CCI Mag primers will be used. Looking for a goal of 1200 fps.

If your happy with 1170 fps from a 200 gr. projectile, I would say LongShot is a great powder. Meters very well, burns clean with mag primers and is the only choice I would use from Hodgdon in the 10mm with heavy bullets. I hear HS7 burns dirty which is not what I want when I'm shooting 300 rounds in one day at the range with tight clearances on a KKM barrel.

Still can't wait to reload using AA#9.

G-20er 09-19-2004 21:14

Did more testing with LongShot this past weekend using slightly more crimp to match factory crimp specifications. I was very surprised at the increase in velocity.

Some observations:

I didn't expect much from this powder and frankly I wasn't disappointed! In some samples, pressure signs manifesting themselves in "smiley's" came on quite early. So, I had to scrub a few samples for safety.

The 10mm cartridge was tolerant with this powder, but it was not the case for .40. For the 180 gr 40 SW, don't look beyond about 1050 fps, or else you're flirting with bad pressure signs. The numbers for 200 gr 40SW are too low for serious velocities, but showed no signs of pressure either.

I've heard it said that Universal was the answer to the aged and decrepid Alliant Unique. To be honest, I didn't notice any cleaner burning and certainly didn't notice better velocities with Universal. To its credit, it does meter somewhat better than Unique, though.

Well, my results show that this powder is well suited as a mild plinking powder as it was intended to be. I have been surprised with certain other powders with supposedly similiar burning speeds and have exploited them with no signs of sacrificing safety.

G-20er 09-23-2004 22:05

oh my gosh...I read the entire post...not that I gave a care about the cheasy powder your wasting your time with, I was hoping to hear some good stories. This post is way to this your other personality? It has got to be....hello, BuffaloBo where did you go.


Can't you see your going the wrong direction on the powder burn speed chart? I'm still curious as of what powder is your favorite and why.

BuffaloBo 09-24-2004 17:29

Can't you see your going the wrong direction on the powder burn speed chart? I'm still curious as of what powder is your favorite and why.

Well, the reason why I checked this powder out is not to exclusively see what it can do in 10mm, but to see what it can do in a variety of calibers. I shoot a total of 5 pistol calibers. I check out powders not primarily for raw speed, but more so for versatility, or in this case "Universal-ity" (pun intended).

It is argued that Universal is the heir apparent of the "lowly" Unique. Since they are similiar, I thougth to see how they compare. I wasn't straying but a tiny bit the other way of the burn rate chart. I hope you don't think that I'd be crazy enough to push this powder to extreme limits to show that it's "possible". If YOU don't feel comfortable in pushing where it seems possible, I certainly won't call you a wuss.;)

No, I don't have another personality. I believe, however, that certain powders that I've worked with previously had the ability to be pushed farther than what are listed by conservative compilers of data.

What kind of stories were you hoping to hear, anyway? I consider myself to be a thorough and safety conscious field tester. I examine EVERY case thrown from a pistol for signs of trouble. BTW, I know that you're being humorous. :)

My favorite powder? -Don't have just one. Included among them are (not in any particular order): Blue Dot, Winchester Super Field, AA#7, Unique, and Winchester 231. If I get a single powder to perform well in at least 3 cartridges, I am well pleased. All of the above, with the special exception of W231, which is relegated to low pressure plinkers for powder puff 40's and 38 specials, leave me feeling well pleased.

If I was to be given the choice of a single powder to use, I'd give the nod to either Unique, or then to WSF.

Oh, and by the way, to anyone who may be interested, MY results show that Unique trounces Universal.;f ;a

G-20er 09-29-2004 13:51


What does Unique or WSF powder have over the 5 powders I listed as my favorites? I Would like to hear why these are your top two choices for the 10mm?

BuffaloBo 09-29-2004 18:05

I thought I made myself clear in my previous post?:)

I honestly couldn't contrast or compare your five choices with anything I've used because I've never used any of your choices.

My choices come down to a compromise between versatility and velocity.

In 9m using a 124 Gold Dot:

Unique: 1180 fps @ 6.0 gr
WSF: 1260 fps @ 6.2 gr

In 40 using a 180 gr FMJ:

Unique: 1107 fps @ 6.9 gr
WSF: 1086 fps @ 6.6 gr

In 357 Sig using a 124 Gold Dot:

Unique: 1401 fps @ 8.0 gr
WSF: 1418 fps @ 8.4 gr

Finally, my results for 10mm are recorded in this forum for inspection.

As you can see, these are very good numbers. They may not be the absoulute TOP numbers to be had, but it shows you that these 2 powders are capable of excellent results.

Remember, I also mentioned Blue Dot and AA#7 as favorites also. Blue Dot is excellent in all except 9mm. AA#7 has given extraordinary results in all of the above, with the exception of 2 little things. First, it requires more charge than any other powder I've used for similiar effect. Second, I noticed slight "smilies" when I started to push the 40's.

Won't you share your reasonings with us?:)
