Little to no information is available to reload this round, Federal uses a 38 Super bullet other use the 9mm bullets, I read the historical post on this and it provided little information other than some people have had problems. I'm fanitacal when it comes to reloading I lube all cases then resize, I trim all cases, I run all cases through a simple green bath, then reload. I expect feed problems a first. I like the varity of 38 Super bullets but what are the problems because there is little reloading information. Let me know what you all know please?

Got an extra barrel for my Glock 27. I then went and bought 1000 pieces of once fired Speer 357sig brass. I regret it. Only way I can load for it and not worrry so much about driving the bullet back in the brass on a cycle is to use a Lee factory crimp die. I have to use a 40 cal and put a 9mm sleeve in it.

I love the 40 much more.

I got a .357 Sig barrel for my Glock 23 as well. Don't like the recoil impulse - very sharp and harsh. I'm also sticking with the .40 S & W.

Bigcountry, I know that problem with 357 Sig and the cure, but I need to know several things. Federal had the same problem

1. Are you using lead, lead copper washed, or copper jacket?
2. Whatcal bullet .355, .356, or .357?

I have tried Hornady XTP and Speer gold dot. All 9mm bullets. Tried the 147gr. and the speer was the one made for the 357 sig, .355".

Then you got to dump the 357 Sigpowder die for a 9mm powder die. You have to use .356 38 Super bullets for the 357 Sig reloads. Read below.


Hornady 124, an Remington 124 and a 115 Gold Dot; none of them can be seated to maximum COL without the ogive entering the case neck and reducing case neck contact. Of the three shown, only Hornady lists their product for use with the 357 SIG. Remington, Speer and Sierra (not pictured) specifically limit the 9mm selection when making recommendations or posting handload data for the SIG round. Each cites the problem of unacceptable neck contact as the reason for omitting certain 9mm bullets that may work well in other applications

Boy, you got to be careful with this and 40 SW cased rounds. They can build pressure very quickly and dangerously. Also, highly not to try .356" bullets in glocks barrels. There special rifling does not permit cast loads. So I sure wouldn't experiment with .001" greater diameter bullets.

Think I will be happy with the healthier 40S&W round. Makes a bigger hole and much easier to load, and no lubing of cases. Win, win.

Well all Federal factory 357 Sig uses .356, tell you what use your micrometer if you have a 9mm powder die and check it aganst the 357 Sig die.

Well, you may be right on target. I will let more info surface if it ever does before I go for it. I experiemented for months on this round and gave up.

The Speer Gold Dot ammo for 357 Sig uses 125 grain bullets right, here is the link to Speers Gold Dot bullets and calaber and weight. You will notice the only 125 grain Gold Dot bullet is for 38 or .357caliber, you may also notice they have a 147 grain in the .357 size also.

Remington uses a 125 grain bullet for it's 357 Sig ammo, and yes the only bullet Remington makes in 125 grain is .357.

Federal uses 125 grain, and the only 125 grain bullet they have is .357.
