That is why you always start with the starting load and work your way up watching for indications of pressure.Ĭlearly you are free to use whatever powder you choose, but using a slower powder (where you have already seen there are lots more choices) will give you a greater safety cushion while you perfect this new skill.To bad you are so far away or I'd sell you some 3N38. So even though your 124 gr matches the load if it is a different bullet and a different length the pressure could be different. The other issue is that bullets of the same weight may vary in length due to the profile. So if you don't have adequate neck tension because you expanded the case neck a bit too much and the bullet gets driven deeper into the case when it hits the feed ramp, suddenly the pressure goes up 40% and your pistol is overpressured. Have you looked at the Powder burn rate chart? The issue with using a fast powder on the 9mm is that it can make changes in seating depth result in some pretty dramatic pressure changes. Especially for someone just getting started into reloading. But what you are seeing is that Titegroup is a fast powder and that isn't necessarily the best option for 9mm. There are some loads listed on the Hodgdon website. I won't use a powder with the possibility of a double charge of powder. Typical loads come up to the base of a seated bullet or even lightly compressed. The nice thing about Unique for me is that with typical charges there is NO WAY that a case could be double charged. I do see several discussions in searches where people do use Titegroup in 9MM. A chronograph helps working up powders when specific bullets and powders aren't published. I seat most 124 FMJ's to 1.150" oal but Winchester 124 FMJ's I seat to 1.160" as they have a more pointed tip shape. I've seen no issues with 5.1 grains with the 124FMJ's in different pistols with various cases but all using CCI 500 primers. For several different 124 FMJ jacketed and plated round nose bullets I've loaded 4.8 grains of Unique for a milder load and up to 5.1 grains of Unique for more velocity. No experience with Titegroup powder, I use Alliant Unique for 9MM 124 gr. ![]() Also you are reluctant to use others on-line recommendations. Finding proven data in a manual for your bullet choice and powder preference is sometimes not easy. It seems to me the Lyman guide doesn't contain that much on 9mm, which is a bit of shock, I thought it would contain more data. In the Lyman guide I see 115gr JHP and it show Titegroup, I also see that it recommends Power Pistol as the powder of choice, but I don't see any options for 115gr FMJ. Does this mean for for 124gr & 115 gr FMJ that Titegroup is not an option? I want to make sure I understand what this is telling me. The powder that I was thing of using is not listed for the 124gr bullet weight Titegroup, however it is listed for 115gr Lead and 115gr XTP. In the Lee manual I can see 124gr Jacketed Bullet ( I will assume this is equal to FMJ?) and it shows a number of powder options. To get the load data, I went to my Lyman 49th edition page 341 looking for 124gr FMJ, but I don't see any data for it, the only data I see for FMJ is 95gr. ![]() To start with I plan to load for the range, I have been shooting 115gr FMJ factory loads, but I would like to hand load 124gr FMJ which is what I have for my SD loads. I'm just getting into reloading and I will be starting with 9mm and have some questions on looking up loading data for the 9mm.
