I need .40 S&W lead bullet load data!

I need load data for .40 S&W using a 170gr lead bullet. The bullets are actually "coated" bullet from Precision Bullets, but they advise to use lead bullet data.

The powders I have on hand are W231, WSF, AA#5, and AA#7.

Thanks!

W-231 from 4.5-5.4gr
AA#5 from 6-6.2gr
WSF from 5.5-6.3gr

I have no data on AA#7

They were from my notes and Reloaders digest 1997 or 96, they had an article on cast bullets loads in the 40. I don't have a 40 S&W anymore.

When I 1st started to load for the 40 with cast bullets(Mine) 170gr cast with WW(these were for a 38-40 I still have) I used 38-40 starting data with unique powder. The loads were from a Lyman manual.

My 40 S&W was a S&W 4006 and it shot the above loads ok. I never really warmed up to the 40 so I got rid of it.

Use the starting load I posted and work up. If you are shooting out of a Glock you may need to start a little higher to get it to function good.

There is very little cast bullet data for the 40 S&W. You may want to try the Cast bullet Forum over at Beartooth Bullets.

Good luck with the 40, mine never really impressed me with accuracy.

I can help a bit with published data for the AA#5 and AA#7.
I have two guides from Accurate.

From the 1992 Accurate guide:
Bullet weight is listed at 175 grains, which makes it perfectly safe for you to use as a guide for 170-grain bullets. Data is also denoted as LEAD bullet.

.40 S&W, 175gr Lead, AA#5, start: 6.2gr, 917 fps
--------------------- AA#5, max: 6.9gr, 1,030 fps

From the version 3.2.2 Accurate guide (2005, 2006?):
.40 S&W, 175gr Lead, AA#7, start: 7.5gr, 823 fps
--------------------- AA#7, max: 8.3gr, 925 fps

This guide lists a general COAL min of 1.095" and general max of 1.135" for all .40 S&W loads





From the version 3.2.2 guide (2005, 2006 or thereabouts?):
.40 S&W, Laser Cast SWC(L) 170gr, AA#5 start: 5.5gr, 868 fps
-----------------------------------AA#5 max: 6.1gr, 986 fps 35k psi 1.115" COAL

.40 S&W, Montana Gold SWC(L) 175gr, AA#7 start: 7.6gr, 892 fps
--------------------------------------AA#7 max: 8.4gr 1,014 fps 35k psi 1.115" COAL


NOTES!
--These are not my loads and I have never tested them. Neither I nor TFL take any risk for anyone's use of this load data-- use at your own risk.
--These are published loads from a powder manufacturer, but note that the first loads listed are from 1992 and the powder blends may have changed over time. In fact, I think Accurate has been bought and sold since that time.
--Yes, the loads do vary, for many reasons, and that's why they are guidelines, as is ALL data.

Check Accurate's web site for a downloadable PDF file of their latest published guide for more data or to double check this info.


Hope this helps.

Thanks guys. I'm loading these to shoot USPSA at major power factor so they won't be "light" loads. I'll use this data as a starting point and shoot them over the chronograph and watch for pressure signs.

They'll be shot through a Glock 35.

I've never shot competition pistol in any form at any level...
But if I did, my first inclination would be to ask some long established shooters with the same caliber what they are shooting and go from there.

Lyman #49 - Winchester SP primer, 4" barrel universal receiver, .401" groove diameter (yes, it really says .401" and not .400").

40S&W 150 gr Lyman #2 Alloy TCFP 1.090" OAL .401" sized bullet:
Bullseye 5.0 gr (1056 fps) - 6.0 gr (1202 fps)
W231 5.5 gr (1079 fps) - 6.5 gr (1195 fps)
AA #2 5.0 gr (1041 fps) - 6.4 gr (1192 fps)
N340 5.3 gr (911 fps) - 5.9 gr (1057 fps)
Zip 5.0 gr (934 fps) - 5.6 gr (1067 fps)
Silhouette 6.8 gr (1000 fps) - 7.2 gr (1108 fps)
Unique 5.0 gr (980 fps) - 6.3 gr (1196 fps)
Power Pistol 6.3 gr (971 fps) - 7.0 gr (1112 fps)
AA #5 6.3 gr (969 fps) - 7.5 gr (1195 fps)
N330 5.1 gr (927 fps) - 5.7 gr (1064 fps)
HS-6 7.5 gr (1038 fps) - 8.8 gr (1224 fps)
800X 6.8 gr (1085 fps) - 8.0 gr (1180 fps)
Blue Dot 8.3 (1033 fps) - 9.6 gr (1171 fps)

As others posted, you can use heavier 155 gr load data for lighter 150 gr bullet. More 155 gr lead loads in 2004 Alliant load data.
