Lee 358-105 SWC in 9mm

[tazman]

What is everyone seating these to in your 9mm? I am having feed problems with mine.

I needed to seat mine a little deeper than I would have expected to get them to feed. Only a little of the top drive band exposed. Similar to the large picture posted above.

I casted up 850 of these a few weeks ago loaded 50 of them in 357 cases 10 each with 5 different powders . herco and 2400 seemed to shoot the best out of my s&w 686, I also used 4227,700x,and bullseye . I loaded 50 of them in 9mm cases (sized at .356)with 3.8 gr of pb and attempted to shoot them from my sr9c . it was a jam o matic every other shot jam I attempted 2 mags full it was pointless . they did however shoot great out of the 9mm cylinder in my ruger blackhawk 357-9mm convertable

I tried and tried to get these to work in my gun. I played with the length and crimp all over the place. As long as I only loaded 6 in my 13 round mag, they would work. The gun is a clone of the CZ 75 compact.

[tazman]

What did the ones that didn't load correctly do exactly?

I haven't had any success with these in 9mm, tried some that I hiteked the other day feed fine accuracy was still terrible 25m groups could be measured in feet but they were at least all on the target this time.
Out of a 686 revolver using 38 cases I can keep 10 shot groups under 2" at 25m.
In 357 cases from a marlin 1894 pushing them at around 1100fps 50m groups are 1 1/2".
Shot a few rabbits with this combination and it works well.

Stove piping. When they made to the chamber they shot good. But I don't like my handguns to be a single shot.

Work perfectly for years in a Browning HP.

Is there a commercial bullet that this is close to for using a base starting point to work up a charge from for 9MM? I've got bullseye and unique and will start casting from this mold very soon and would like a good starting point in both of those powders. Will be shooting through a walther 9mm.

This is the only thing I can find (from Handloader Issue #255). It has load data for a 104gr bullet (close enough) but I see some stating 3.0 to start which is well off 4.0 below.

Warning! Notes: Test gun was a SIG Sauer P226 9mm Luger with a 4.4-inch barrel. All velocities measured approximately 10 feet from muzzle using an Oehler Model 35P chronograph. Ambient temperatures varied from approximately 65 to 85 degrees Fahrenheit. Loads assembled using Winchester 9mm Luger brass and CCI 500 standard Small Pistol primers. No reduction in overall cartridge length (OAL) is recommended. Any change in components requires powder charge reduction. This data is intended for use only by persons experienced in the proper and safe practice of handloading ammunition. (Handloader Issue #255 - October-November, 2008)

Wt.	Bullet	Powder Manufacturer	Powder	Charge	Velocity (FPS)
104	Lyman 356632	Alliant	Bullseye	4.0	1128
Remarks: overall loaded length (inches): 1.03
104	Lyman 356632	Hodgdon	Titegroup	3.8	1115
Remarks: overall loaded length (inches): 1.03
104	Lyman 356632	Accurate	AAC-5	5.5	986
Remarks: overall loaded length (inches): 1.03; poor accuracy

Those look like max loads

This is a page from the Lyman cast bullet handbook 4th edition. It is for the Lee 102 rn boolit but should be reasonably close since it is only 3 grains difference.

Thanks, Tazman!

Would be if the Lee came out at 105gr mine are 110 or a little heavier and a few others I know with the same mould get similar weights.
Given this I just start with 115gr data.

That works too.

Thanks for the data, guys, on bullet weight.

For what it's worth, a gentleman that goes by the name of FortuneCookie45LC and makes a TON of videos on Youtube, stated he's getting 111 to 112 grains for clip on wheel weight from his 358-105. As you've stated, I think I'll find 115 grain recipes for LSWC TC and go with that as a starting point as there are tons of recipes for that in Bullseye.

For Example:

9mm Luger / 9mm Parabellum (Lyman Cast Bullet Handbook 3rd Edition) Reloading Data	Printable Version
Warning! Notes: The trim-to length should be adhered to closely. A short case or crimp on the mouth can cause problems with headspace. Most popular cast bullet for this caliber is #356402. Cases: Federal (except where otherwise specified in remarks); trim-to length: .751"; primers: CCI 500 (except where otherwise specified in remarks); primer size: Small Pistol; Lyman shell holder: No. 12; cast bullets used sized to .358" dia.; firearm used: Universal Receiver; barrel length: 4"; twist: 1-10"; groove diameter: .358"

Wt.	Bullet	Powder Manufacturer	Powder	Charge	Velocity (FPS)
115	Cast #358345	Alliant	Bullseye	3.8	1035
Remarks: sugg. start load; OAL: .997"; case: Win; primer: Win 1 1/2-108; 22,800 cup
115	Cast #358345	Alliant	Bullseye	4.9	1200
Remarks: max load; OAL: .997"; case: Win; primer: Win 1 1/2-108; 31,000 cup

The 358-105-swc sized to .357 at OAL 1.000 in lead feeds fine in my Glock17 but stovepipe jams in my Beretta 92FS. When I powder coated them they still don't work in the 92FS and now occasionally stovepipe jam the G17. I think the OAL is too short to kick the nose down and chamber the round. The plain lead must slip better when the nose hits the chamber and the PC sticks a little bit more.

Except that swc's generally seat much deeper than RN.

When you compare these 2 boolits, I don't think there is going to be a significant difference in seating depth. Both boolits are very short.
My seating depth was only about 10-12 thousandths different.

[sigep1764]

Is this boolit similar in length to the Lee 356 120TC? The tc is fairly accurate in my 9s but I am looking for a second mold to test accuracy and punch cleaner holes.

[tazman]

The Lee 120 tc measures .574 from my mold.
The Lee 105swc measures .534 from my mold.
However, the bearing surfaces are identical in length. This is the part that would be inside the case.
The nose on the 120tc is a bit longer and heavier than the 105swc.

Thanks Tasman. That info and pic was exactly what I was looking for.
