.40 S&W Suggestions

[Glenn H]

So, just got a .40 4006 TSW. I am reloading 10MM now and with an easy peasy change I can do the .40 with the same die.

So far, so good.

Now I need to find out the 'right' bullet for POI. I imagine that the 180 gr is the standard that the pistol was built to but...always looking for suggestions.

I'm going to go to the range with a variety of store bought rounds, 155, 180 etc to see what works but thought I'd ask if anyone here has particular success with anything.

My 1006 seems to like 180gr moving around 1050fps or so. I'm using HS-6.

I'm also wondering about the 'belly bulge' on .40, is it mostly with the Glock unsupported chamber or is this something I need to manage with the 4006? Do I need to buy a pass through sizing die or no?

Thanks for any and all suggestions

The buldge is from the unsupported Glock chamber. If your gun fully supports the case, no need to get the buldge buster die.

My wife just purchased a 4006 tsw and we are shooting factory 165 gr bullets. I was trying to lessen the recoil for her with the lighter bullet. I loaded some 5gr bullseye wuth that bullet and it wouldnt function only had the gun a week and one trip to range. The gun is very touchy about getting the case flare to original spec I had a few wouldnt chamber had to put more taper crimp on them. My 45 and 9 mmare much more forgiving good luck

165 grain bullets and Power Pistol.

No need to worry about bulge.

suggestion for 40S&W

I reload for a M&P 40 and a 4006, and after lots of testing my favorite combination for accuracy and comfort is Ranier Ballistics 165gr flat point round shoulder plated bullets, 5.0 gr of Hodgdon Tight group. This works out to about 1,012 fps.

This is way over the power factor required for IDPA competition, but it works so well for me it is not going to get changed. If there is any issue, it would be that the 4006 starts to put some soreness in my elbow and wrist after about 100 rounds. I have not experianced this with the M&P.

You may need to vary the bullet seating depth to find what allows for the best feeding in your pistol.

Let us know what you settle on.

145-155gn are often the most accurate.
If working towards a light load, don't forget that you can switch out for a lighter recoil spring (I put a little yellow tape around the front of the trigger guard so I know by looking that the gun has a light recoil spring). As you go down in velocity, move up in powder burn rate--AA2 and Am. Select are very good for light target loads.
POI is determined by the bullet weight and velocity, where lighter recoil (lower speed or lighter bullet) lowers the POI. To be pedantic, where ever the bullet hits is POI. You are trying to match POA.

Thanks all

Thanks all for the suggestions. Ordered a 1000 loaded rounds (can't reload for the cost of the loaded ammo) so I'll have lots of room to play with building loads.

I appreciate the help, this is a great forum for information.
