Hodgdon Powder data.

Discussion in '10mm Reloading Forum' started by MCNETT, Aug 25, 2003.


  1. My first light practice load.
    Stock G-20
    165 Rainier plated TC/FP
    1.272" COL
    R-P nickel brass/CCI 300 primers
    5.3 grains Titegroup
    1,001 fps.
    Two failures to extract-slow slide velocity I'm sure.
    Excellent accuracy though, puts my G-21 to shame.
    My chrono (Shooting Chrony F-1) seems to read consistently about 50-75 fps fast, for example CCI Blazer 200 clocked 1,050, which is faster than most results I've seen from a stock G-20, other calibers are the same way.
    I'll edit this post as I work this load up, but I couldn't find any Titegroup data for the 165's, so I thought I would post.

    I am really happy with the consistency of the 8.2gr load, which is Hodgdon's listed max. I have 2k WLP's on the way, and I may pick up some CCI350's to see if that will help kick up my velocities. With a 1247fps average for a 200gr bullet, there's nothing really to complain about. But as always, I want more...

    I am pretty happy that 8.2gr of Longshot load beats DT's factory loaded 200gr WFNGC's out of my gun. Here's what DT's ammo did out of my G20L the same day:

    1199, 1220, 1173, 1227, 1216

    Nice report. Thank you for the nice information. Longshot has been one of those powders I have never gotten around to. Yet more evidence that I should pick up a can.

    Primers are starting to look more flat, but I think there's still room to grow. I'm still hoping I can average 1300fps with the 200gr WFNGC's out of my G20L with good precision.

    The only powder I use for the G20 with the 200 grain XTP is AA#9 I would start with 12.5 grains. I backed off from 13.0 and 13.5. 12.5 grains seems the best bang for the powder. I did not find much velocity improvement over 12.5 of AA"9 in a Barstow barrel.
     

  7. Merry Christmas! Nice report Wavesport! I've got some 9.6 & 9.8 grains Longshot, loaded in new Starline Brass, 1.258 OAL, CCI 350's and Speer 180 TMJ's to shoot either today or tomorrow. Loaded these on my NEW XL650 Dillon :) (thanks to my wife!) I'll post data soon.

    (End Of Data)

    Seeing significant high pressure signs - smiles, flattened primers and headstamps. Loaded over 100 of these on my Dillon, but after shooting about 20 rounds, I decided brass was looking too stressed. I'm going to back down to 8.0/8.2 grains of Longshot with same bullet, primers, brass OAL etc. next. I'm hoping to achieve ~1250 - 1300fps with a 180 grain TMJ bullet.

    I found 9.6 Grains of Longshot to be pushing what I'm comfortable with loading in my 10mm Glock 20. Smiles with primers and headstamps flattening. Nice velocities for a 180 Grain bullet, but IMHO seems to be at case limits - those cases are no longer in the reloading pile. The 8.2 grains of Longshot seemed to perform about as expected. I'd like to get 1250~1300fps, so an increase to 8.4 grains may be the ticket. Cases looked fine with the 8.2 grains of Longshot and appear to have room to grow.

    These loads were done on my Dillon XL-650. Velocities obtained from a CED M2 Chronograph with Infrared Screens.

    Hope this data is useful. Have a Happy and Safe New Year!

  10. Picked up some longshot and would like to do a little reloading while awaiting new barrel, spring, etc.. Out of a stock Glock 20 what would be the starting loads for 155 XTP and 180XTP using longshot. Experienced reloader and will take any and all advise at my own risk. Many thanx
     
  11. My data for a 180 grain TMJ is ~100fps more and brass looked stressed:

    Do you think it's the six inch barrel and sea level?

    I'm looking to develop a 180 grain CMJ/JHP at ~1300fps. I seem to be getting close to those velocities with 8.4 grains of Longshot (.1 grain less than minimum?). Go figure? Just puzzled... any ideas or suggestions? :shocked:

    Out of a KKM 4.6 inch barrel with 11.5 gr LS New starline brass CCI 350 1.257 COAL I got 1477ft/sec primers Ok but would drop to 9.3 gr for a stock barrel and work up slowly. Published data from Hogdon shows max load @ 9.3 gr 31500 psi so there is some room to go beyond.
     
  13. Here's Hodgdon Data:

    Cartridge: 10mm Auto
    180 GR. SIE JHC Hodgdon Longshot: Starting Loads - 8.5 Grains, fps 1221
    Maximum Loads - 9.5 Grains, fps 1287
     
  14. That's smokin' Tex! And, that's a stout load of Longshot! Did you get 1477fps with a 155 or 180 grain XTP or both?

    It is smoken. That was with the 155gr XTP. I only load lighter bullets because I don't hunt and very hot 180 and 200gr bullets are more for 4 legged threats and the chance of a thru and thru on 2 legged treats is greater. My last post I stated that Hogdon max load for 155Xtp was 9.3 that was for a .40 not 10mm but velocity for ths .40 load was 1283 ft/sec. at 11.5 gr in the 10mm 200 ft/sec is not big stretch. Someone else posted that they used 12.5 gr but From the numbers I got with 11.5 I would not go any higher. That load may be too hot for 2 legged threats with the XTP.11.0gr gave me 1420ft/sec and was more accurate and probably safer. Have not fired in a stock barrel so I can't safely recommend going that high in the stock barrel. Next time out I will see the condition of the brass out of my stock barrels.
    I use a 165gr Golden Saber in new Starline nickel plate brass with a 10.0 of power pistol (max published load) CCI350
    1.255 -1.258 1396 ft/sec 4.6 inch barrel SD 11.4 for my carry loads.

    Made my first workups with Longshot powder. Stuck with Hodgdon book data. My initial impressions are favorable. While I hand weighed each charge, it is a pwder that meters quite well. I have heard the nickname, "loudshot" in the past, but it did not seem noticeably loud. It was certainly not loud like Blue Dot. It burned relatively clean. Somewhere between 800-X and Accurate 9/7 powders in terms of powder residue and cleanliness.

    There is nothing too exciting here, but I thought I would add some data points to the sticky.

    Firearm: Gen 3 Glock 20 with 22# Wolff spring and steel non-captured guide rod. Stock barrel.

    Temp: 90F

    Brass: Starline
    Primer: CCI 300
    Powder: Hodgdon Longshot
    COL: 1.26"
    Crimp: .421" as measured at the case mouth

    Vel: 1038

    8.2 grains (Hodgdon book max)
    Vel: 1146

    Note that this load penetrated cleanly through five water-filled milk jugs.

    None of the loads exhibited symptoms of excess pressure. Maximum case expansion was gtg. Groups were all respectable.

    I have several strings of 180 gr XTPs loaded. I will post the results when available.

    Taterhead, thanks for posting the data...
    LongShot, does a good job and is one of the powders to use with the 10mm. I had used almost all of my 1 lb jug of LS for my 9x25Dillon project, but have just a little to test a few loads with.
    For me right now, I am trying to use my new 5 lb jug of Blue Dot. It may go pretty fast with a ton of 10mm, 40S&W and 357Sig to load.

  18. This data is posted in response to whenmonkeysfly's issue with his 9.6gr 180 load. Since I had almost the exact same setup, except standard (CCI#300) instead of mag primers, and my brass did not suffer at all. I measure case head expansion just above the extractor groove on the webbing of the brass. For my new Starline, my average is 0.4220".

    4/11/2011, 180gr XTP, 9.7gr Longshot, CCI #300, New Starline brass, 1.255" OAL, 62F, 22lb Wolff spring.

    Sd 8.02

    Notes: Case heads .4226 - .4232". Light to moderate ejector/extractor marks.

    Stock G20 barrel, same load, same day/conditions, using the 22lb Wolff spring:

    Notes: Case heads .4232 - .4240". Light to moderate ejector/extractor marks.

    My objective was to get 1300fps out of the stock G20 barrel without any signs of brass stress, and this load made that criteria easily. It also makes an excellent 1400fps hunting load from the 6" barrel.

    I know there are varying opinions on standard vs. magnum primers and when to use each, but comparing my data to whenmonkeysfly's load with a similar set up, main difference is primers, it would appear that .1gr more powder and a standard primer achieved the same result with much less strain on the brass.

    Hope this helps!

    Just wanted to post this data since I do not see a lot of info with the 10mm, Longshot Powder and the 155 Grain Bullet. This load could go hotter or milder, but I wanted a relatively soft shooting, accurate, full-power load with reloadable brass for my Dan Wesson Razorback Limited Edition. (This load seemed to fit the bill.) Power Factor of 193 +/-, so it's in the "majors" easily. You can get similar results from a .40 S&W, but I think you'll beat your gun to death in relatively short order IMHO.
