You have some stuff to start with. You can get some of it from Shadow for different powders and Max pressures. Use colors to show which are at the extreme end or over.


Shadow what does the chart look like on that DT 135gr with 11.4-11.5gr's of Long Shot for pressure?

Certainly The_Shadow should feel more than welcome to chime in as he already has.  That said, I'm not sure what The_Shadow would have for different powders and Max pressures outside of what we know from the different powder manufactuers (which seem to vary a tad oddly to me) which is somewhat limited itself, and whatever QuickLoad might suggest that more commonly than not to me seems way off base.  Not to mention we would need to know what magin of error is to be expected.

I think at minimum, for us to be able to take anything meaningful at all from the data, would be for a single independant pressure tester to test all loads in question under the exact same controled circumstances.  Two would be better yet, but I expect that's asking waaaaaaaaaaaay too much.

Intercooler the pressure charts I posted were done by another person, I met thru the 10mm circle of forums, he used the Quick Loads program to crunch the data I supplied him.  I can't speak to the accuracy of what was the output and 800X was not in the powder list.

Still the only way to be sure is to send ammo to be test by a certified lab using SAAMI regulated and calibrated tools and test barrels.

I been shooting the Armscor(black,yellow and white box)in the compact witness,elite match and g20,no problems with brass after shooting and in the compact it packs a punch.Has punch for plinking knowing you got something.Of course not full load.

Kevin said 37,000. Rock on!

37,000 for all his 10mm loads?

I have limited experience with vendors, buying mainly Double Tap, Buffalo Bore in the past and Underwood recently. Buffalo Bore has their act together when it comes to loading. But, their product became "unsafe" when they placed bullets not intended for self-defense (Montana Gold) into rounds I wanted for self-defense.

Personally, out of a) .40S&W levels, b) Norma levels, or c) 'On the upper edge' levels, I'm looking for b). If I need more, I'll carry my .44 Mag.

If someone offered good quality rounds (e.g. Starline brass, GD or XTP bullets) that send 180gr bullets out at 1300 ft/s and 200gr bullets at 1200 ft/s with consistent mid-level standard deviations, I'd be a happy camper.

The only vendor I'm aware of that uses decent components and provides performance above a .40S&W is Underwood. I've bought nearly a thousand rounds of theirs to add to my stash.

Kevin seems to be still working out kinks in his loading procedures. One video showed his .357 Sig rounds performing far below box label specs. Kevin acknowledged the mistake and apologized. Then, there seems to be occasions where rounds go a bit over the upper edge.

These days, it's hard for a business to start.  Big government doesn't help. And Internet can spread the word about small start-up mistakes.

I'll continue to buy from Underwood. He wants to get things right and our feedback is helping him do that.

I'll second that. I really like the Underwood 9mm 124gr +P and +P+ loads for my carry gun. Good stuff, and very consistent.

All loads.

I wonder which way a range of psi from the 37,000psi heads, and to what extent, with the UW 200XTP between the velocity spread of -1240 to 1300 fps using 800X.

It's too much. Like Harry reiterated, we don't need upper edge level loads to shoot in our stock guns.

My suggestion....since Kevin is already specifying a downloaded 10mm for Delta Elite pistols, why not run some standard Norma level loads and then specify some hot stuff for the guy with the fully supported barrels and heavier recoil springs?

This will give all the 10mil customers what they want.

I don't want that. One can get that through doubletap.

Double Tap doesn't get you there unless you're using a 6" barrel, in a G20 anyway.

   I haven't put the billboard out yet for PBR Ammo because Anthony doesn't have his Starline brass yet. After I prodded him to do the 165's for us in full-power he agreed for $21.30 a box. Just no brass yet to order them. If you want something more mild his specs are from a Glock 4.6" all stock:

165gr- 1306 FPS/ 625 LBS
180gr- 1263 FPS/ 637 LBS
200gr- 1200 FPS. It isn't even listed on the page now so don't know where it went. I will ask.

**Also keep in mind the limited testing I did of his ammo it surpassed the sites specs in my 10's**

Keep in mind Kevin said you are safe firing any of his ammo out of a supported chamber even in stock condition.... Delta Elite is the one that shouldn't!! He honestly thought about dropping the Delta specific totally at one point. For those owners I guess good thing he didn't.

I am not sure what you don't want? Did you misread my post?

I suggested Underwood offer different level loads, ie,, some standard pressure (Norma level) loads for our stock guns, as well as some upper end loads for the guys that have the guns and desire to shoot these loads. Double Tap does not apply here.
