thehudge Posted February 8 Share Posted February 8 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 Share Posted February 9 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. Quote Link to post Share on other sites
Gpghost Posted February 9 Share Posted February 9 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. Quote Link to post Share on other sites
36873687 Posted February 9 Share Posted February 9 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 Quote Link to post Share on other sites
thehudge Posted February 9 Author Share Posted February 9 The only powders I have in stock are TG and WAC. I used to load 9major, I wonder if that would be safer? Quote Link to post Share on other sites
Gpghost Posted February 9 Share Posted February 9 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. Quote Link to post Share on other sites
HCH Posted February 9 Share Posted February 9 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. Quote Link to post Share on other sites
Aircooled6racer Posted February 10 Share Posted February 10 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 Quote Link to post Share on other sites
noylj Posted February 10 Share Posted February 10 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. Quote Link to post Share on other sites
stick Posted February 10 Share Posted February 10 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. Quote Link to post Share on other sites
RudyVey Posted February 10 Share Posted February 10 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... Quote Link to post Share on other sites

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 Quote Link to post Share on other sites
SteelCityShooter Posted February 10 Share Posted February 10 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. Quote Link to post Share on other sites

I can't find any information that says this is a safe load. but I like it. Seriously? Have you looked at any reloading manuals, or online reloading info? Everyone would show this load is above max. 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 by Postal Bob Quote Link to post Share on other sites
IHAVEGAS Posted February 10 Share Posted February 10 Anyone know how an overpressure failure from shooting several rounds of slightly too hot ammo manifests? Just curious. Quote Link to post Share on other sites
thehudge Posted February 11 Author Share Posted February 11 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 Quote Link to post Share on other sites

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 Quote Link to post Share on other sites
Aircooled6racer Posted February 22 Share Posted February 22 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 Quote Link to post Share on other sites
9x45 Posted March 1 Share Posted March 1 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? Quote Link to post Share on other sites

9x45 Posted March 19 Share Posted March 19 Any of these powders will work well. Quote Link to post Share on other sites
