Anyone have a favorite 9mm load using Promo powder?

[Matt Dillon]

Folks, I have some Promo powder that I would like to use, for 9mm loads, underneath either a 124 or 147 copper plated bullet. Does anyone have a good, tested load that you can recommend ? Thanks so very much in advance!

I like 124 grain Hi Tec Small Ball with 4.0 grains of promo.
Also generic124 FMJ with 4.6 grains promo work well in all my 9MM pistols.
Seems I have 2 eight pounders to use up so I have been testing for a common load that is accurate.

124gr Acme coated RN over 4.6gr Promo.

EDIT: While I like this load a lot, it is pretty hot (feel, recoil), and I recently cut back to 4.4gr Promo for general target shooting. Either load is good; you'll just have to find what runs in your pistols the best.

4 grains of Promo, under a 124 jacketed bullet

Livelife has posted Promo info in 9mm in a lot of threads here a quick search should turn up something.

I have only shot a little Promo but I was using 4gr with a MBC 124 cone. Seemed to shoot well, back before I had my chrono so no vels.

Promo ... 9mm ... 124 or 147 copper plated bullet.

Does anyone have a good, tested load that you can recommend?

This link has my load development for Promo with 95 gr to 147 gr 9mm bullets - https://www.thehighroad.org/index.php?threads/9-mm-loads.865271/#post-11429686

Per Alliant, I referenced 2004 Red Dot load data by weight for my Promo load development - http://www.thehighroad.org/attachment.php?attachmentid=182147&d=1364769070

• 9mm 115 gr FMJ Red Dot OAL 1.120" Max 4.5 gr (1150 fps)

• 9mm 125 gr Lead RN Red Dot OAL 1.130" Start 3.3 gr (888 fps) - Max 3.6 gr (1004 fps) *This is Speer load data and note shorter OAL and lower powder charges - https://www.speer-ammo.com/download...gun/9mm_caliber_355-366_dia/9mm_Luger_125.pdf

• 9mm 125 gr Lead (RN?) Red Dot OAL 1.150" Max 4.5 gr (1,145 fps)

• 9mm 125 gr FMJ Red Dot OAL 1.150" Max 4.6 gr (1,145 fps)

• 9mm 147 gr XTP Red Dot OAL 1.140" Max 3.4 gr (895 fps)

For 147 gr Z-Cast Lead FP at 1.155"-1.160" OAL, Glock 22 with KKM 40-9mm conversion barrel was tested with reference load of 3.5 gr W231/HP-38.

3.1-3.3 gr Promo reliably cycled the slide and produced light recoil. 3.3-3.5 gr produced greater accuracy with mild recoil and produced following groups at 10 yards

For 124 gr Z-Cast "stepped" Lead RN at 1.125" OAL, 4.0 gr of Promo. For 124 gr FMJ/plated RN, I load to 1.130"-1.135" with 3.8 - 4.0 gr of Promo.

BTW, for 115 gr FMJ/plated RN, 4.0-4.2 gr of Promo but loaded shorter at 1.110"-1.115" produced mild recoil target load. 4.4-4.5 gr of Promo produces firmer recoil on par with factory target load with greater accuracy.

I have only shot a little Promo ... before I had my chrono so no vels.

Here are some Promo chrono data (These are carbine loads so subtract around 200 fps for pistol velocities. BTW, Promo is reverse temperature sensitive - Higher velocity at colder temps) - https://www.thehighroad.org/index.p...n-9mm-40s-w-45acp.799231/page-4#post-10338994

115 gr Berry's HBRN 3.9-4.0 gr Promo @ 1.135": 1275-1261-1316-1287-1294 fps (59 F - PSA carbine)
115 gr Berry's HBRN 4.5-4.6 gr Promo @ 1.130": 1414-1377-1375-1420-1372 (75 F - JR carbine)

115 gr RMR HM RN 3.9-4.0 gr Promo @ 1.135": 1204-1276-1259-1273-1247 fps (59 F - PSA carbine)
115 gr RMR HM RN 4.0-4.2 gr Promo @ 1.135": 1331-1358-1346 fps (59 F - PSA carbine - ran out of test rounds)
115 gr RMR HM RN 4.5-4.7 gr Promo @ 1.135": 1351-1364-1363-1357-1342 (71 F - JR carbine)

124 gr RMR HM RN 3.9-4.0 gr Promo @ 1.160": 1231-1201-1210-1227-1193 fps (59 F - PSA carbine)
124 gr RMR HM RN 4.2-4.3 gr Promo @ 1.160": 1258-1263-1251-1244-1266 fps (68 F - PSA carbine)
124 gr RMR HM RN 4.2-4.3 gr Promo @ 1.160": 1298-1277-1261-1276-1293 fps (68 F - JR carbine)

Revised my post.
