Hi all.so today i made few 9mm ammo and try it at the range.it was 124 grain campro tmj,with 3.8 grain tight group.shoot well, but i find the casings had dark fouling from powder, and it seems like waz more than it should be.does anyone has any thoughts about that?
First time 9mm reloaded and shoot toady.

That is the same recipe I use and same result. I just tumble them and use them over and over again, no issues.
Cool great to know someon else uses this recipe.do you taper crimp the brass? Im only using as last the bullet seating die , which so slightly crims the case, every where i looked it says that extra crimp is unnecessary for 9mm,except one book by Sweeney, Reloading for handgunners.also my OAL is 1.130

Also, i had little thoughts about this sealing issue.and i will speak here not from place of experience but just logic.if the base of projectile dont expand to fully to seal the barrel , than logi ally speaking the gasses would escape pass the projectile forward leaving the casing less dirty.on the other hand if the barrel is well sealed then part of the gas back up staining the brass.like i said this is just theory.maybe the actual science is different?
you got it. remember your powder drop never drops the exact same. could be 3.7, 3.9 4.1 even though you very thoroughly set it at 3.9gr.
You need to account for this when your loading bulk at minimum or maximum powder weight. Maybe 3.9 is enough to seal the brass in the chamber.. Maybe its enough for a Winchester case but not Remington, and etc etc etc.
Reloading is finding what works for YOU and Your pistol. Never ever 100% trust what is said by anyone else, use it only as a guide to point you in a new direction!

I know my book show's 4.3gr max for 124gr and titegroup. Personally i have loaded up to 4.8grains and shot 500+. (It was a mistake i made on the loading bench. Instead of pulling each bullet, i did a proper workup and the brass/primers showed little signs of pressure.) I deemed them safe to shoot in My pistol which i trust enough to put that much pressure through.
When you think your at maximum, check your brass as you shoot it and look at signs of wear or pressure.. Flat primer or bulging out(imprinting the hole for the firing pin), cracked cases or hard to extract.
Min/max loads in books are simply guidelines too.
Have fun!

i use the same projectiles with 3.8gr of titegroup as well. OAL 1.12", 0.376 crimp
i loaded 200 rounds at 3.9gr to try and see if the carbon fouling on the casing goes away.
i got to buy a chrony so i can check the velocity of my rounds.

I have been playing with this same load myself and this is the info that campro sent me
The data load for Cam Pro 9mm 124gr RN with Titegroup is 4.1 to 4.4gr
You can use lee data load for 9mm 125 fmj.
And the OAL is 1.120 and taper crimp 0.376
I loaded up mine using 4.1gr of titegroup and had no issues in my xdm9

This type of fouling happens all the time. If the chamber of the gun is a little oversized and the powder charge doesn't create enough pressure to fully expand the casing into the chamber, there will be a little bit of blow back. Unless you are getting noticeable gas coming out of the back of the gun I wouldn't worry about it but I might be inclined as others have said to bump up the powder by .1 or .2 grains to see what happens. Experimentation within the published limits is the joy of reloading.
I frequently see references to the max being 4.1, however if you look as Chef says, Campro says load as FMJ.
Then if you look up FMJ Titegroup data, range is 4.1-4.4.
I see many references to people loading at quite a bit less than that (3.8-4.0 being common).
I admit to that confusing me a bit.
Is what you see at the mouth, fouling or scorching?
I looked up some info due to seeing a burning effect, and it appears to be quite common and due to titegroup being very hot and fast.
It appears to simple burn so fast that some escapes before the case expands enough to seal, even with proper pressures.
Google it to find many references, but this one had photos representing what I discovered.

That's just what I've found as a novice, and I'll be reading along with interest.
Hodgdon makes the powder so I'd go with what they say. And the Hodgdon reloading website data matches what I've got in my Lyman 49th manual so I tend to believe that these two are closer to the truth.
Titegroup isn't the cleanest for soot inside the cases. But hey, it's not as bad as the 231 that I used one time only. I'm pretty sure that stuff left lumps of coal inside the cases.
Some powders leave the cases surprisingly clean while others soot up the insides. It means nothing at all as long as you're getting the correct muzzle velocity and low variation in speed and that the gun cycles like it should.

Hodgdon's site doesn't say that though.
You need to go with the only FMJ listed (according to Campro), which is a 125gr (close enough).
Formatting is lost, but here it is (4.1-4.4).
