Bob DuBois Posted May 27, 2014 Share Posted May 27, 2014 Bring your OAL out seems to me the longer you load the more accurate. I'm using Frontier 147 with 3.4 of Solo 1000 OAL 1.145. tight groups out of my STI Trojan. Link to comment Share on other sites More sharing options...
tac_driver Posted May 27, 2014 Share Posted May 27, 2014 crimp to 2x the case wall thickness + bullet diameter i was using berry's 147gr. plated bullets and winchester cases cases are .12x2 = 24 24 + .355 =.379 my crimp was ending up .377 - .378 oal is 1.150 titegroup 3.5gr ES: 14.25 SD: 6.24 2in groups at 15 yds PF 137 Link to comment Share on other sites More sharing options...
shotdown Posted May 28, 2014 Share Posted May 28, 2014 I'm loading range 9mm brass with 147 gr X-Treme bullets and I'm pretty happy with the grouping (I haven't measured though). They are through a G34 with a 13 lb ISMI spring. I'm loading: 3.3 gr Titegroup Win SP Primers OAL: 1.160 .378 after flare removed My chrono results: 976 958 957 953 956 Avg: 960 ES: 23 SD: 9 Link to comment Share on other sites More sharing options...
texasref Posted May 28, 2014 Share Posted May 28, 2014 Shooting the same loadings as Shotdown witht the exception of 3.2 grs and coated 147's. Chrono results basically the same (135 PF) I would seat a little longer 1.160 and see if that helps out Link to comment Share on other sites More sharing options...
FireNHole Posted May 28, 2014 Share Posted May 28, 2014 (edited) I shot a test load a few weeks back with 3.2 gr of TG with the .356 diameter 147gr xtremes at 15 yards and got .75in grouping with 10 bullets. The OAL was 1.150 and mixed brass with CCI primers. These were shot out of a Glock 34 Gen 4 with 13lb ISMI spring.

AdvocatusDiaboli Posted May 28, 2014 Author Share Posted May 28, 2014 I ordered a pro chrono digital. In not going to shoot any more ammo until I get it. I'm loading some rounds at 1.170 because they passed a plunk test in my gun. Link to comment Share on other sites More sharing options...

thermobollocks Posted May 28, 2014 Share Posted May 28, 2014 Do you get similarly poor accuracy with other powders and the same bullet/OAL? The only other thing I can think to check on might be some of Xtreme's .357 diameter rather than the .356, if that's what you're using. Link to comment Share on other sites More sharing options...

Factory ammo seems to group okay. Link to comment Share on other sites More sharing options...
thermobollocks Posted May 28, 2014 Share Posted May 28, 2014 A different powder would probably help you narrow down whether it's the bullet or the powder, since factory ammo (unless you bought it from Freedom, which uses Xtreme plated bullets in a bunch of their stuff) will likely not use the exact same profile of bullet even if it's the same weight. Whether you'd notice a difference between the Xtreme 147 and factory 147s, I'm not sure, since there are many factors that can contribute to poor accuracy. Do you have any factory 147 available or was it just the 115s and 124s you mentioned earlier? Link to comment Share on other sites More sharing options...

I haven't seen them in any local stores for a very long time. I could order some online, but it seems pointless to buy 1 box online for testing purposes. My chrono will be in later this week. I will do some testing over the chrono to see what I'm getting. I'm also going to tighten up the diameter at the mouth of the case .002" & see it that helps at all.

thermobollocks Posted May 28, 2014 Share Posted May 28, 2014 Looking a little closer at the nose of your loaded ammo, is it printing a ring into it, or is it flattening? My RCBS seater will flatten the tip just a bit, but since it remains concentric I don't run into any issues. Link to comment Share on other sites More sharing options...

shotdown Posted May 29, 2014 Share Posted May 29, 2014 One way to get rid of that is to JB weld the hole of the seating stem on the Dillon Die. You'll have to use a bullet so that epoxy forms to the bullet. Link to comment Share on other sites More sharing options...

Unfortunately, I'm sitting on 3600 of these. I'm not new to reloading... just new to reloading 9mm. I've never had so much trouble getting accuracy before. Usually, with my rifles, I can have a sub moa load in less than 150 rounds. I'm already double that with my 9mm and still no clear direction to go. On a side note, I was at the range last weekend and saw another shooter using blue bullets. No smoke whatsoever. He said the accuracy has been great and he prefers them over the bbi.

AdvocatusDiaboli Posted June 6, 2014 Author Share Posted June 6, 2014 I may be on to something here. 3.2 grains Titegroup 1.170 OAL .379 diameter. All shots 15 yards, 10 shot groups. 1st group (from L to R) chrono results High 974 Low 925 Average 948 2nd group chrono results High 976 Low 929 Avg 953 I did notice that all test loads seemed to tighten up significantly when I changed the diameter from .381 to .379.

Sandbagger123 Posted June 6, 2014 Share Posted June 6, 2014 measure some factory rounds and you will find that they use an even tighter crimp. many measure .375- .377. i would tighten up the crimp a little and see what happens. Also, have you tried loading a full mag with the 1.17 ammo. many times long ammo will work the first few rounds, but get stuck in the mag the further they go down Link to comment Share on other sites More sharing options...
AdvocatusDiaboli Posted June 6, 2014 Author Share Posted June 6, 2014 I loaded the mags with 10 rounds for the test groups. There were no issues. These are plated bullets. Are factory rounds with a diameter of .375 using plated bullets or jacketed? My bullet diameter is .355. The brass thickness is .012 x 2 = .024. Thus total diameter should be .379. Any tighter and I will be scuffing the bullet plating. Do you recommend that? Link to comment Share on other sites More sharing options...
FTDMFR Posted June 6, 2014 Share Posted June 6, 2014 Not sure if this helps, but here's my load data for Titegroup with X-treme 147gr RN CP .356" diameter, WSP, 1.150-1.155" OAL. M&P Pro. All data points are 10-round averages. Charge / FPS / PF 2.6 / 794.9 / 116.9 2.8 / 816.8 / 120.1 3.0 / 871.5 / 128.1 3.2 / 911.8 / 134.0 3.4 / 927.6 / 136.4 3.6 / 984.4 / 144.7 Best fit line FPS = 188.6 * Grains + 299.84 Grains = (FPS - 299.84) / 188.6 So I use 3.1gr to get 885 FPS / 130 PF.

Red Ryder Posted June 7, 2014 Share Posted June 7, 2014 Titepoop likes a 140 PF to be very accurate with tight groups in my G17 and G34! So I no longer use it. Link to comment Share on other sites More sharing options...

Got any advice on how to do this while still being able to flip the stem? It is permanent but I'm able to flip my stem. Maybe that person over did it with the JB weld and now can't flip it. It only needs a little bit of JB weld in the hole, then lightly oil the tip of the bullet and then put the stem on top of the bullet as straight as possible. the JB weld will conform to the shape of the tip of the bullet. I use both Berry's and X-Treme and have no issues. I did not seal the opposite side of the stem since I don't use it. Hard to see but the left bullet had a ring on the tip before I used the JB weld. The one on the right is after the JB Weld. Edited June 7, 2014 by shotdown Link to comment Share on other sites More sharing options...
