thehudge Posted February 8, 2021 Share Posted February 8, 2021 I've been trying to reach mid 1200fps with TG and 115jhp. I did it using 5.6gr of TG and 1.125oal for a 1258fps average Glock19. While my spent primers are a little bit flat there is no other evidence of over pressure. Q: Does this sound safe to Y'all? I can't find any information that says this is a safe load. but I like it.

CClassForLife Posted February 9, 2021 Share Posted February 9, 2021 All I know is that the casing will explode at 7.8gr and you'll have to buy a new extractor and magazine release. Possible small cuts and embedded pieces of brass in the hands too. I think most people will recommend you use a slower burning powder to avoid the Titegroup pressure spike. At 4.0gr, I think it's already near or at the recommended pressure limit. Link to comment Share on other sites More sharing options...
Gpghost Posted February 9, 2021 Share Posted February 9, 2021 I'm a huge fan of tightgroup, but it is not the powder for this job. Does not sound safe to me even at our lax attention to reloading data most of us live by. Link to comment Share on other sites More sharing options...
36873687 Posted February 9, 2021 Share Posted February 9, 2021 Try to find slower burning powder. I did this also wanting 1200 FPS 115 jhp. I used imr4756 but that powder is discontinued . Silhouette would be a good one to do this with Link to comment Share on other sites More sharing options...
thehudge Posted February 9, 2021 Author Share Posted February 9, 2021 The only powders I have in stock are TG and WAC. I used to load 9major, I wonder if that would be safer? Link to comment Share on other sites More sharing options...
Gpghost Posted February 9, 2021 Share Posted February 9, 2021 WAC.. Winchester Auto Comp? I know there are 9major guys using that with 124s, not sure about 115s. It is a slower powder than TG it is right between HS-6 and 3n37. Probably a better choice. Link to comment Share on other sites More sharing options...
HCH Posted February 9, 2021 Share Posted February 9, 2021 Max according to hodgdon is 4.8 for a velocity of 1158 out of a 4" gun. Like others have said, look into another powder. 6 grains of longshot or 7 grains of HS6 looks like your best bet. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted February 10, 2021 Share Posted February 10, 2021 Hello: WAC will work fine with your 115's. I have loaded thousands of them for my open pistol. I am not sure why you want it that hot though? Thanks, Eric Link to comment Share on other sites More sharing options...
noylj Posted February 10, 2021 Share Posted February 10, 2021 Let's take a very fast and hot burning powder, known for pressure spikes, and let's overload it to achieve some random velocity goal. Next, ignore about the only pressure sign you'll get before kaboom and then ask if it is safe. You move to slower powders for more velocity and to faster powders for less velocity/increased controllability. Link to comment Share on other sites More sharing options...
stick Posted February 10, 2021 Share Posted February 10, 2021 The bigger question is...why do you want to push a bullet that fast out of a glock 19? Use a slower powder or risk a kaboom. Link to comment Share on other sites More sharing options...
RudyVey Posted February 10, 2021 Share Posted February 10, 2021 When I used TG, I think to remember my load was around 4.1 for 115 and 3.8 for 124; but then, I do not measure anything with a chrono. Just a basic shooter... Link to comment Share on other sites More sharing options...

Yes, as I said, I am just a plain simple guy who enjoys shooting and rolling my own ammo, don't compete. Using the data that are provided. I do have a chrono somewhere, but it is always a pita to set up in a public range with a lot of others around Link to comment Share on other sites More sharing options...
SteelCityShooter Posted February 10, 2021 Share Posted February 10, 2021 According to the Hodgdon web site the maximum load for TG with a 115 gr jacketed bullet is 4.8 gr so the OP is 0.8 gr or 17% above the recommended max. That's getting into dangerous territory and is probably quite a bit above +P pressure. As above, find a more suitable powder. Link to comment Share on other sites More sharing options...

And just guessing here, you're testing your loads in cold weather, based on your location. Titegroup significantly looses velocity and pressure in cold weather. Shoot those loads in the heat of Summer, and let us know if you still have your hands. Edited February 10, 2021 by Postal Bob Link to comment Share on other sites More sharing options...
IHAVEGAS Posted February 10, 2021 Share Posted February 10, 2021 Anyone know how an overpressure failure from shooting several rounds of slightly too hot ammo manifests? Just curious. Link to comment Share on other sites More sharing options...
thehudge Posted February 11, 2021 Author Share Posted February 11, 2021 Thanks for all replies and rebukes. I will take heed of the warnings. And yes I have loading manuals but decided to venture a bit. I have loaded 125 and 115gr to USPSA major with no issues using Winchester Auto Comp which is a bit of a venture in itself. And that's why I asked. Thanks Link to comment Share on other sites More sharing options...

I have a boat load of WAC and PD 115’s that I would like to run major out of my PT Honcho. Thanks in advance Link to comment Share on other sites More sharing options...
Aircooled6racer Posted February 22, 2021 Share Posted February 22, 2021 Hello, using 115 grain JHP Montana Golds and loaded to 1.170" OAL with Winchester small rifle primers I was using 7.4 grains of Auto Comp giving me 170-171PF out of a Schuemann 1:32 twist 5.5" barrel with my comp. I would start at 7.0 grains and chrono to see what you get. Thanks, Eric Link to comment Share on other sites More sharing options...
9x45 Posted March 1, 2021 Share Posted March 1, 2021 When the case looks like the one on the right, you are getting too close. But why are you trying to run so much higher over the Minor floor? Link to comment Share on other sites More sharing options...
