40 S&W load data

[BMS]

I am looking for help with high and low loads for 40 S&W 180 grain lead (Bayou Bullets) using Titegroup. I called Titegroup today and they refused to give me any load data cause I was shooting lead they were pretty much cut and dry. Any help would be greatly appreciated.

What kind of gun?
3.2gr @1.135 works for minor with a 135 power factor
4.5gr @1.200 for major with 170 power factor

You will need to stay on the short side with the XDM. Start with the load given above (3.2 gr @ 1.135" OAL) and increase your charge 0.10gr until you are happy with the load or you begin to see pressure signs, then back off a tenth or two. Yhere are much better powders out there than TG for 180 gr 40s&w. the pressure can spike really fast with TG. Be very careful whiile working your load up.

I found that at 1.135 OAL, about 4.0g with 180g BB gave me ~930 FPS with a G35 and KKM barrel. Start below that and work up. TiteGroup is not very forgiving if you go too far over too fast. I use N320 for my major loads, as I found it softer shooting for the same velocity as TG. Now for minor loads, TG had a much smaller standard deviation between shots than N320 and grouped better.

As mentioned, Titegroup is sensitive toward max loads. It is also pretty temperature sensitive. I don't have any experience with it in 40, I use N320 and Clays when I can't find Vihtavuori.

What is it about the XDm that requires "the short side"?

Usually it's the magazine that limits OAL. 9mm and 40 XD's are built on the same frame, the 1.20" OAL is closer to 45acp length. Custom 1911 pistols are built on 45acp frames and have their chambers cut deeper to allow for longer ammo. Longer OAL is much more fogriving which is why many that compete with 40S&W do so with the 1911 platform.

I just started reloading I tried the 180g bayou bullets in my sig2022 with 5.0g bullseye at 1.136 OAL- shot fantastic. Well i can't find any bullseye so I got clays and unique. Any users got data to try. Also have 158g .38sp is there a thread for that?
