Lee 401-175-tc for 40S&W

[tazman]

Thinking about getting a Lee 401-175-tc for 40S&W. I have a few questions for those of you experienced with this mold.
What size does it drop with your alloy?
Do you like the performance you get with this boolit?
Do you like something else better?
Thanks for all your input.

Love that bullet. Mine dropped at .402.

I use it for 10mm. Accuracy is better than the accuracy of my old eyes. :)

Hi Tazman,

My M&P 40 loves them. Mine drops them right at about .401. I have settled on the 175gr TN, LLA tumble over 4 grains of Red Dot (NOTE: Standard Cautionary Verbiage = Start low and work up etc) for my go to plinking load. A real cream puff to shoot, very accurate, not a single FTF/FTE.

Be well

I have a 6 cavity that drops at .402 with coww. I tumble lube and run 'em through a .401 push thru sizer then TL again. Shoot them through a Hi Point carbine. They shoot great. It's the only .40 mould I have so nothing to compare performance against.

I love this mold. Using the 6 cavity mold with the Lee 4-20 pot, I can cast about 20 pounds worth of bullets in a couple of hours. I drop these into a towel lined bucket of water not necessarily for hardening, but because the pile grows so fast, I have a tough time pushing them aside when I drop them on a dry towel. This is about an hours worth of casting.

For me, they drop at 0.4025 to 0.403. I was tumble lubing them in 45/45/10 without sizing and seating them to where the cone meets the case mouth. Any taller than that and the bullet would get stuck in the throat of my M&P40. I still got a little leading in the center of the barrel, but would easily remove it with a couple of swipes of a bore mop with Chore Boy strands wrapped around it.

I have since been Powder Coating. This is a mixture of 356-120-TC and 401-175-TC bullets.

And the bore has had zero leading. The remaining soot in the barrel is removed with one pass with a bore snake or one patch soaked in Hoppes No.9.

I love mine. They drop at .4025ish using range scrap at 178.5gn. Quench, 45/45/10 lube. Load and shoot in my G29 as 10mm with LW barrel, or 40 S&W with LW conversion. I fire some FMJs after the lead, and that helps keep down the leading. Leads the snot out of the factory glock barrel, and keyholes. Stupid polyogonal barrel. That's the only down side. If you have a polyogonal barrel, like a Glock, this boolit is pretty much useless. If you have a LW barrel for your glock, it's a FANTASTIC boolit.

i have the stock barrel and I have not experienced any leading. I also use the stock 10mm barrel to shoot .40SW.

I have the six cavity in the TL-SWC version. Cast with a 20:1 alloy and sized to .401. This size gave the most reliable feed in both a stock barrel Glock 23 and a Hi-point. Though this rarely happens, the load demonstrated the same accuracy in both pistols. Shot hundreds of rounds in both pistols with no leading.

You will like the bullet that mold produces.

i have 2 of this mold the older 1 is a double cav older style . this bullet from what I understand people were having trouble with it chambering so lee redesigned the bullet . my 2nd mold is a 6 cav with the newer bullet design . when I 1st started this bullet I was shooting a hi point and never had an issue what so ever . i just casted ,lubed loaded and shot. so i casted up a bunch of them for my father inlaw and he had chambering issues with his s&w mod 99 . later on i dumped the hipoint and upgraded to a Taurus pt100 then i started having chambering issues myself if i remember right the bullets were dropping around 402 with wheel weight alloy . so i bought a lee 401 sizing die resized all my bullets then tried them out in the Taurus and in the s&w with no issues . i load these bullets over 5.6 gr of herco they shoot great from my Taurus i also have a s&w sigma and that load feels like its gonna rip the gun out of me hands so i load them over 4.5 gr of win 231 . ive also had good luck in the past with this bullet over power pistol .

Good design and ran well in a Glock both with a factory barrel and a Lone Wolf barrel. The lone wolf barrel I had to throat as it didn't have one really. Mine dropped at .4015-.4020 and is a more recent 6 cavity mold (about a year ago).

[petroid]

I like it better than the SWC mold. My 6cav drops a .402 with COWW or 50/50. COWW gives 180gr and 50/50 183ish. Shoots very well and hits hard. AC 50/50 pb/COWW expanded to 60 cal at 950 fps into dry sand.

[tazman]

Thank you gentlemen. I appreciate the input.

[harley45]

My 6 cavity drops at 402 also, I powder coat them and run them thru my 10mm. It's one of my favorite target molds.

My Glock22 leaded worse than snot with this boolit, I changed to a Storm lake barrel and this is a great boolit for it. My only complaint is the lead pot is emptied too fast.
It shoots quite well also in the Glock 35 (KKM).

I love mine. They drop at .4025ish using range scrap at 178.5gn. Quench, 45/45/10 lube. Load and shoot in my G29 as 10mm with LW barrel, or 40 S&W with LW conversion.

I like it for my 40's. They drop @ .403 get sized to .402 for the Smith and .401 for the Kahr.

[tazman]

Since everyone who responded liked it for a standard rifled barrel, I ordered one today. Should have it by the weekend.
Thanks for the help making up my mind.

[leeggen]

Tazman just seat them so you have about 30 to 50 thousands of the top band showing and I'll bet they feed well, mine does great and I have the TL-401-175-TC drops .4025to .403 with 50/50+2%.

Good information to have and I expect you are right. I use the same depth on a similar boolit in my 9mm.

What size does it drop with your alloy? .402 - .403 ( acww )
Do you like the performance you get with this boolit? Yes
Do you like something else better? No
