using 3.5 gr tite group ,124 gr lead rd nose bullet not much info in my books use lyman pistol data mostly ,any thought s have a lot 4#

Hodgdon lists a load online for a plated bullet with a starting load of 3.6 gr at an OAL of 1.15".
I'd say that load is OK depending on your OAL.
-
One of the cautions experienced reloaders point out here is the very small window from minimum load to maximum load you get with Titegroup.
Be very careful not to go over maximum or double charge with it.

I agree. The big "depender" is your OAL.
At 1.150" you're probably near Starting Load. At 1.050" you might be approaching Max Load. The 9x19 Luger cartridge is very sensitive to changes in OAL.

This subject may have been covered in another thread, but it's just what I've been wondering about- when working up a load, do you fix the o.a.l. first, then make a ladder of charges? Once the best powder charge is identified, do you go back and do a ladder of o.a.l.? I had heard that for 9mm there was an ideal bullet seating depth and if you can't use the resulting o.a.l., to choose the closest you can to that depending on the gun it's meant for and the powder manufacturer's recommendation. Or choose a bullet that with proper seating depth give you the o.a.l. you're trying to achieve? Is there a reason to stray from a seating depth in hopes of fine tuning a round?

Right now I'm loading 124 Gr plated round nose at 1.155 OAL and using 4.1 Gr of Tight Group. It's an accurate load but not quite hot enough to knock down the bigger steel. I'll be increasing powder weight by another 1/10th grain or two next time I load.
[Mods added the correction since the poster did not]
Thank you for the edit. A one grain increase would be catastrophic.

I think @ 4.1 gn you are close to max with a 124 gn bullet. I have a similar load worked up in Quickload and it tells me that 4.2 gn Titegroup is over pressure. Be careful and work up in 0.1 gn increments if you feel like you need the extra power.

All depends on OAL. You are correct, only 0.1 Gr at a time.

4.1 is the max load on the Hodgdon site.
The thing about Titegroup is there's only 100 fps gain between starting and max load. I don't think a tenth or two is going to raise anything except pressure.

This is a rather pointless thread.
• The OP has not told us the bullet he plans on using. The bullet determines the OAL. Without OAL information, any discussion of load is pointless.
• The Hodgdon load information is laughable. First of all they show 1 load for 124gr and 1 load for 125gr. So there's a lack of data. And all the recipes are shown at an OAL of 1.150" which is crazy because no one uses a long OAL like that, not the factories and not reloaders, especially in a CZ chamber.
• As Painter poignantly points out, there's simply not much to be gained with TiteGroup powder.
:P

I started to use TG because it was cheap, plentiful, and was not so full in the case to spill on rapid shell plate rotations (I had a 1050 and now have an automated press). At IDPA PF it’s dirty but I clean often enough.
I have too much of it not to keep using it but will prolly change after its gone.
With a Berrys 124 grain round nose plated Bullet I never went over 3.9 grain before I met my chrono goal, at lengths up to 1.125

Right now I am loading Gallants 115gr round nose coated bullets over 4.0gr of Titegroup at a COAL of 1.100" with whatever small pistol primer and brass I can find.
This has proven to be a very good range load.
Titegroup does have a small window between min and max for most loadings. Always double check and check the powder charge regularly.

You are certainly welcome.
• While TG is popular, it's also very sensitive and dense.
• It's a very easy powder to double charge due to the very small volume. Its volume is so small, you may actually see velocity differences depending upon whether you point the gun Up or Down just before the shot is taken. That is to say in small loads and/or large cases, the powder becomes "position sensitive". This should definitely be included in your testing.
• There's another thing you need to read between the lines to understand. Because of the requirement for fine metering, most of the guys using this powder are using high-end powder measures that are extremely accurate and repeatable. This is not a powder you want to use with "scoops" or other inaccurate or beginner equipment. This is not a powder you want to use if you do not understand how much your powder measure varies over 100 'drops'. You need to become super wary, quantify your powder measure output, and 100% checking needs to become part of your process.
Not trying to scare you. Just trying to point out the difference between 'inexpensive' and 'easy to use'.

Having a lot of it isn't really a good reason to use it if you're new to reloading(guessing you may be). I started out with Tightgroup, but quickly learned there are several other powders that are superior and safer. The only upside to TG is price. I would trade it off locally or put it up for the next shortage.
