175 Gr 40 S&w Reloading Data

[rocky082259]

I'm trying to find reloading data for the 175 gr. cast bullet for 40 s&w. I can't seem to find anything on the 175 gr.

thanks

5.7 gr of AA #5 cycles a Glock 22. Max load for this powder is 6.1
I use this powder in 9mm and .40

Try Lyman's 48th Reloading handbook, it has loads for 9 powders listed for 175 gr cast bullets.

I've been loading the Lee 175grain TL SWC with 4.4 grains of WST at an OAL of 1.135" with very good results. Velocity is around 900 fps.

Use 180 gr lead data= Unique, IMR sr 4756 Clays, titegroup and you will find a load that works great. Using a 180 will give you a slight safety factor. The faurty is tough on the hand and hard on the heart.

[trickyasafox]

son of a gun I shoot a lot of those- I use unique for all my loads but don't have my books in front of me.

[randyrat]

I had some very reliable results with Unique, although dirty, you need to run Unique on the higher end for cast. I had accurate,reliable,clean results with the faster powders Clays, Titegroup. But if your going to use a progresive press with fast powders, case fillout/fillup is not good with most of these fast powders in the forty. REMEMBER THIS*** you don't have to worrie about the squib load it's the next round that could mame or kill you. Fast powders like Clays one can easily make a Squib then a double charge and KABOOM. There is no room for mistakes with the high pressure rounds such as the 9mm and 40. So phisical checking each case is a must. Now with a little caution have fun.

i used aa7 with 175/180 in my 40's

Seconds on the SR4756. IIRC it's around 7.0 grains. I don't have my booklet handy.

Just tested out a new 40 load with the 175gr cast SWC. It's a reduced IPSC load:

4.7gr W-231
1.127" OAL

Works good out of a USP and an XD.

Wow, the XD actually feeds the SWC reliably ? I have to feed my XD's either RN or TC cast bullets. SWC's have been a nightmare for me.

[tbtrout]

I use 5 gr of 231 with a 175swc in my XD. feeds reliably and shoots well.

[arclight]

Yep, the SWC works fine in mt XD subcompact. I'm using this boolit - sort of a trucated cone SWC with a bevel base:

5.5 grains of Ramshot Silhouette in my 4" XD puts a magazine worth into 1 5/8" at 25 yards. This is a start charge, and is very easy on the shooter and pistol.

I use alliant power pistol in my CZ40p. I use the data for the 180grain fmj(shooting 180grain cast bullets). IIRC the load is 6.8-7.2. I have tried that entire range and prefer 7.0. Cycles nicely and accuracy is good.

OAL has a lot to do with feeding problems with SWCs. Certain handguns - like the 1911 - have such a vast wealth of experience behind them that you can research most combinations of bullet, powder and OAL and find a pretty good starting point. With less common pistols, you have to do more research and personal experimentation. I'm just finishing working up a good 175 gr. LSWC load for a Taurus PT-840 (.40 S&W). Very small differences in bullet seating depth make this pistol reliably feed/chamber or experience endless FTF malfunctions. Needless to say, slightly different bullet designs can influence these things, too. With a 1911 it is common to use a LSWC seating depth where the driving band is "a fingernail's width" above the case mouth. On this particular Taurus my best seating depth is less than that, with the driving band just barely visible above the brass. Needless to say, this might not work as well on a different pistol...so again, you have to do your own experimentation. Also, as a (very) general rule for LSWCs you should err on the side of shorter OALs - being aware of increased pressure with short OALs - rather than longer ones.

A lot of experienced reloaders get this wrong. I recently spoke with the owner of a small reloaded ammo company on the southern Gulf Coast; he said some customers were complaining that his .45 ACP LSWCs weren't feeding well. I asked to see a sample round and he had most of the first driving band above the brass. I shared the "fingernail width" rule with him and the customer complaints stopped.

Best regards

I've been using 6.5gr of AA#5 for my 175gr cast boolits for quite some time, years in fact. Just picked up the latest Lyman Reloading Manual #50 at a weekend gun show and in that tome it shows 6.1gr as a starting load with 6.9gr being maximum for the 175gr cast boolit. The 6.5gr load works fine in both my Glock 22 and Taurus PT140. After reading this thread I may try backing off a bit and see if it changes anything regarding functioning and/or accuracy. Always interesting to hear what others are using.
