Running Titegroup and 175 LSWC in my SAM. Shoots very nice. Load on a 550 and highly recommend the Lee carbide factory crimp die.
Reloading the. 40 s&w

The "Glock bulge" is not limited to only Glock pistols and can happen with any barrel/feed ramp that leaves too much of the case unsupported.
I have a newer Glock .40 and do "NOT" have a bulge problem. And after the problem developed Glock changed the angle of the feed ramp deceasing the unsupported area of the chamber. This was followed by the ammunition manufactures making the cases thicker in the base.
Below "actual" Glock .40 barrels and the changes made.
I buy bulk once fired brass in .7.62, 5.56, .40 S&W, and 9mm and throw out any ,40 S&W cases with the Glock bulge. You are warned not to reload these badly bulged .40S&W cases with the "smiley face" because the bulge and sizing will weaken the case and it can fail. This does not apply to cases with a slight bulge around the entire base of the case
I also pick up any .40 S&W brass I find at the range, and visually inspect it for defects or bulged cases.
Also remember you have SAAMI minimum and maximum chamber and cartridge diameters. And any time you have a chamber on the large size and a case on the small size you will have a bulge around the entire base of the case..
Example below, these two British .303 cases were fired in the same No.4 Enfield rifle. The Prvi case is larger in diamter and .010 thicker in the base than the HXP case. And there is nothing wrong with the HXP case and they are noted for being good cases and long case life.
Below is a "Glock bulge" Google search in Google images and it covers more than Glock .40 S&W pistols.

The "Glock bulge" story/myth is spread by people who do not own a newer Glock .40 S&W. They also do not know that Glock will replace these older barrels. And the vast majority of the cases I find at the range with the bulge are fired by people that do not reload.
NOTE, all my bulk once fired brass I buy is run through a small base rifle die or a Lee bulge buster the first time I size the cases. This returns the cases to minimum SAAMI dimensions, thereafter a standard sizing die is used on the cases fired in my firearms. Also remember chambers and dies vary in diameter and you can over resize your case diameters making them extremely Coke bottle shaped.
And you do not need to load any of your ammo at or near maximum for your practice loads.

If you're picking range brass that you aren't 100% sure came from your gun - you should assume you're getting some old Glock 40 cal's left-overs and at least check for bulged brass in the pile.
I'm wary of anything on the range floor that didn't come out of my gun; regardless of the caliber. "Free" isn't always "free".
I have a newer Glock .40 S&W and most Glock bulge stories are spread by people who do not own a Glock.
I have only ever picked up 3 or 4 Glock cases with the "true" Glock bulge at the range and "none" of the bulk once fired .40 S&W I buy has ever had a true Glock bulge.
I have seen cases that expanded more around the entire base of the case and a Lee bulge buster will return these cases to minimum SAAMI diameter.
And my .40 Lite loads never bulge a case and size easily in a Lee carbide die.
800X(I think 7.2 gr?)
"I think, with a question mark" doesn't make for confidence building reloading data.
Anyone reloading should check and recheck load data from many sources!!??
