Ammo MFG's you consider unsafely loading 10mm offerings

[REDLINE]

I wouldn't choose any.

The only load inexistence that gives me pause is Underwood's 200gr XTP load.  But I wouldn't check them in a poll like this as I have no issue with any other load they offer to my knowledge so far.

   I'm confused about it all. I thought we wanted high performance ammo but now it seems we really don't. I need to look at Buffalo Bore and DoubleTap because I don't think they put any warnings out. I sent Kevin a note on the pressures and all. See what he says maybe he will take them backwards.

My 2 cents is the shooting public wants 10mm loaded to the original spec full power velocities.

For example, a 200 grain load @ 1200 feet per second. Nothing fancy or extreme, just a good 10mm load.

Here is what I think, Underwood is using IMR800X for his loadings based on what I have seen from other peoples pull downs.
His 800X powder loading is at the 37,500 psi SAAMI pressure and fit the MAP, full spectrum.  Also the original IMR data shown was as follows;  WARNING this is the old published data!

Nosler 135gr. JHP with 14.5 grains Hi-Skor 800X yielded 1670 fps @ 33,100 psi
Remington 155gr. JHP with 11.6 grains Hi-Skor 800X yielded 1475 fps @ 32,900 psi
Winchester 180gr. JHP with 9.7 grains Hi-Skor 800X yielded 1320 fps @ 34,200 psi
Hornady 200gr. XTP with 8.4 grains Hi-Skor 800X yielded 1190 fps @ 33,900 psi

It has been said that the newer 800X powder doing a little better velocities with slightly less powder.

Underwood's has tapped into this using quality powder metering devises in his operation. (because 800X doesn't meter that well)  Many people are put off by 800X for this reason, but in my hand weighed testing I have found it to be very repeatable results. 

Now for the twist...800X and LongShot are nearly identical in velocity results by the same charge weights in 10mm from my test but LongShot tends to develop more pressure.

Do you have that sheet of the different powders and pressures?

Based on this they are all within spec of SAAMI.


Anyone know Clark in here:

He has shot double charges and still has his hands

[The_Shadow]

I have read many post from Clark...he is out there...way out there!  One he mentioned he blew up a barrel once and welded it back together.    That was the end of following his work for me!

Here is he older data from IMR

[REDLINE]

If you are posting to me, no, I don't have a sheet of the different powders and pressures.  I would like to see it.  Can it be seen in a link?  Or is this a google doc or something?

I see Clark said;  I have shot 14.2 gr 800X with 200 gr in a Glock 20 10mm Bar Sto barrel repeatedly.

I'm not sure 14.2gr of 800X would fit at a COL length of 1.260.  Does anyone here know?  If it's possible I would expect it's compressed to the extreme.

Let's argue it is possible.  I'ld be VERY curious to know what chrono results show for that load.  Clark talks of shooting it over a chrono for bragging rights.  Doesn't say if he actually ever did, let alone list any velocity.

What I do know is that some powders simply poop out from any or too much compression, at which point velocities can simply flatline at a certain level, or even drop.

Does anyone here have further knowledge on this with IMR 800-X?

[Intercooler]

Yes double compression. Bullet tear downs show Kevin's loads near what is listed here.

Never saw Clark's Chrony numbers. Don't really care to either.

[The_Shadow]

I noticed in that post that Clark doesn't have pertanate data to the load he is shooting either...
NO Velocity readings for repeaded shots!
No COAL listed...
NO primer info...

Personaly I consider him the kind of guy if you did something he did it bigger, better, more, faster....there is a term for that!

What is, or how does one attain, double compression?

Does that mean max uncompressed for a given bullet at a given COL, times two?

Or what?

[Intercooler]

Who's pulling down a DoubleTap and Buffalo Bore to see what's inside?

Redline you should work up an Excel sheet compiling all the weights and powder types by bullet weight with the known. Didn't look like BB was identified but Long Shot for DT which is what I heard.

[REDLINE]

I somewhat considered something like that, but don't feel I have data for enough different 10mm loads overall to warrant it.

[The_Shadow]

I'm not sure but the Buffalo Bore looks like Power Pistol, I'd need to have a sample to study then have to test to be sure the results match!

[Intercooler]

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?
