I have been using Titegroup recently which chrono'd great at 3.4 gr with a MBc 125 g LSWC; very low SD. I have tried 2 different OALs (recently) : 1.095 and 1.075 " I think the crimp is right at the sample bullet in Lymans.

I can't seem to get good accuracy from this combo though it might be the gun a Springfield A. 1911 in 9mm, with a 2.5 pound trigger job for Bullseye. I'm shooting at 25 yards and comparing to the accuracy I get from my stock 1911 Dan Wesson 45. The 9's just don't perform that well. I shot them out of a Sig 225 which isn't meant for targets but it almost performs more consistently than the SA.

Thoughts - OAL, crimp, do I need more powder?

I use 3.6-3.7gr titegroup wth 125gr TCTL lee boolits in a g19 as far as I can seat them out, cant remember the exact number, aint at home, but have 2 tumble lube grooves showing
works fine, no leading once I started pushing em harder.
working with lead in 9mm can be tricky, quite a bit of factors to hammer out.
try seating them out a little bit further closer to the lands
 
3.4 works well for me and others who tried it. I shoot unsized LEE 125 RN at about .3565/.357.
 
I haven't heard from anyone using Missouri Bullets 125 LSWC yet. I'm very curious about your OAL and crimp if you are out there.

I had started with a longer OAL (1.110 if I remember right) but shortened it because the 9's have been shot from 3 guns and the longer rounds had some issues in the 2 Sigs I shoot. I could make 2 sets, longer for the 1911 and shorter for the Sigs.

Thanks for all the replies...
 
Are you having any leading problems? TG burns extremely hot to be using with lead. If your leaded up you will not have any accuracy. Inspect the barrel for leading and clean out if needed.
 
Yes barrel had lead. The Missouri Bullet is BN 18. Most of the lead was on the chamber side of the barrel with a bit reaching out into the rifling. I've seen threads where many members use lead with Titegroup.

To eliminate leading loosen the crimp or increase the load, or both?
 
The area of leading is due to both the hot gases and maybe undersize. TG burns too hot for lead in my book and leading will be expected. I would confirm your bullet fit is 0.001"+ over your bore. I would probably go 0.002" if I was forced to use TG in 9mm. The tighter you can get this to fit will help cut down on gas cutting. Run minimal TC, just enough to remove the flare. With the harder 18BHN you may need to run near the upper end.

Good luck. A lot of people have trouble with leading in the 9mm.
 
I will try to correct if possible.

I was hoping to shoot the Springfield in 9mm, which I use for Bullseye with a 22 conversion, as it would save me wasting 22 rounds on practice. I can make the 9mm lead rounds for the same cost as a slightly better 22, which are hard to find.
 
Dardas 124g LRN using 3.9g TG, OAL 1.125. great accuracy in G17 and P89. No leading.
 
To eliminate leading loosen the crimp or increase the load, or both?

I would increase the load. Hodgdon's on line data says between, 3.6 and 4.0gr with a 125gr LCN so take it up a bit to the start load and go up if the leading doesn't disappear or accuracy is poor.

Correct sometimes about the low SD.

When I compared accuracy to SD for Green Dot using a Hyskore rest, my SD was never higher than 20 and shots grouped 1 1/2" at 25 yards using a Baer Wadcutter. The occasional high or low fps shot when compared to the group was either about 1" high or low outside the cluster.

I have measured Titegroup with a chrono and it had an SD about 10 for several strings measured. I will include a pic of shots this weekend from the hyskore rest and the Springfield Armory 1911 in 9mm ain't no Les Baer - combined with questionable accuracy with the Titegroup - it's hard to say one or the other is more responsible. I need a 9mm accurate to 25 yards to test the Titegroup. Anyone want to send me their CZ75? :)
 
As others have suggested, your load seems too lite.

Bump it up by .2, .4, .6 gr test rounds.

Mine is much closer to a max load & it's more accurate than I can shoot.
 
I did an accuracy test with my .40 M&P using Berry's plated 165 Gr. and Unique. I used data from Lymans manual which does not specifically list that combination. I did get a good starting point and made 12 of each powder weight. I actually went above the Lyman suggested but was just below max for jacketed. What I found was that particular combination gained accuracy with increases in speed. the groups shrank with the increase. Then the max load opened back up in grouping.
Ok ... I know this aint 9mm and Titegroup but, point is I found the sweet spot for that loading with my pistol. and it just took time and patience.
 
Thanks for the info. Don't know if I mentioned OAL is 1.095 and crimp about .380 and the bullets are LSWC not plated. I don't have my manual but isn't 3.8 'ish tops for lead at around that weight?

I will try higher, I also thought of trying lower like for Bullseye shooting but Titegroup may be too fast burning.
 
I tried using Titegroup powder with lead bullets once. They leaded terribly. I think if I were to try lead bullets again I would use 125gr .358 bullets with softer lead, around 10-12 brn, and resize them to .357 before I ruled out lead bullets/Titegroup recipes all together .

With the right recipe I would think that Titegroup would work as well for lead bullets as Bullseye or any of the faster pistol powders. It's a matter of figuring out why your leading. May not be related to the powder at all.
