Suggestions for a 200-ish grainer mold for a 10mm auto (about .40 cal)???

[Russel Nash]

Sorry, only get to this site once a week or so.

I push those 200 gr. WFN's to 1,250 fps.

When I used to shoot USPSA/IDPA matches, we would go by "power factor". PF is bullet weight in grains times velocity in feet per second.

It usually gives a number in the 100 or 200 thousands.

You drop the three digits on the right and just keep or use the 3 digits on the left.

In your case, the PF is 250.

As a comparison, Winchester White Box .45ACP is a 196 power factor out of my 5" 1911s.

So you all's 10mm loads pack quite the wallup.

They should be good med'cin for bowling pins.

I went with a 40-200G from Accurate. I think it is very sim to the 40-200F.

The 40-200F is close to your "G", but quite a bit narrower in the meplat. Yours is pretty nice boolit!





Here are the "F"s.

Another vote for the MP 402-200 "Oreo" mold.



These are dropping right at 200 and .402. Used the cup point on these.. Coated and sized to .402. Center is 50/50 lead/WW +2% tin and the outside ones are 20:1. Both at 1165 fps out of my G20. They feed well when I'm not screwing around with recoil springs. Finding out that Glock factory works just fine. I don't think I need to squeeze every bit out of it. These will do just fine. I gas checked these, but I'm finding that while they help gas cutting some, the barrel remains clean without them....

Oh, these were shot into Clear Ballistics 10% gel at about 15 feet. Penetrated the whole 16" block and caught in the rag box behind, so not sure about total penetration.

Those look great! Very nice expansion.

I agree on the RSA. When I tried a 22 lb Wolff sssembly, I had slide-over misfeeds with hot ammo. The stock RSA is reliable for my ammo in the G20.

+1 on the MP Oreo, does well in my HK USP compact, my brother’s XDM, and my wife’s Sig Pro SP2022.

NOTE: I saw this thread was still going and my previous post had the pics go away. Couldn't edit it so I decided to repost.


WFN means Wide Flat Nose, a nomenclature that Veral Smith of LBT uses.

I shoot 10mm from various autos and a revolver.

Since I also shoot .40 I have various lighter moulds for that that also work in 10mm. I use the cheap Lee 175 gr. 6 cavity to make shooting loads for steel plates, I have a pair of the Lyman 200 gr. TC moulds, I have a NOE 200 gr. mould TC mould for making heavier bullets that I can load long in the .40, I also have that NOE mould posted above to make heavier loads and lastly I have a LBT 200 gr. WFN mould to make my full power everything loads.

A few pics:

Here is a pic from L to R :

200 gr. bullet I pulled from some doubletap 10mm ammo
the 200 gr. WFN CG from my LBT mould
the Lyman 200 gr. TC bullet with only one of the two lube grooves filled up





Here is a pic of the WFN bullet loaded in between a 9x25 and a 180 JHP in 10mm





Next is that NOE 200 gr. TC bullet below you see it unloaded, loaded to .40 length, loaded long in a .40 case and loaded in a 10mm.





I also make my own .40 jacketed bullets using fired 9mm cases as the jacket. I can make some interesting things that you cant buy in the store just by using the right combo of fired case and bullet core.

In the Pic below L to R:

195 gr. JHP using 9mm case
195 gr. JHP with cannelure for revolver shooting using 9mm case
210 gr. JSP using 9mm case
240 gr. JHP using a longer 38 super case as the jacket
