Anyone with Data w/ 10mm, Power Pistol, and Sierra 150gr jhp




Looking for data for this load. I found a couple on handloads.com showing 9.7gr PP and 150gr JHP. I just like to see it published somewhere before I go and use anything I find on the internet. I done a quick search here and google but didb't find what I was looking for. I didn't see anything for 150's with PP on the allient site or my Lyman 49th. If you have a load with different powder and don't mind sharing that would be great too. All imput is appriciated. I just have aquired some 150's that I would like to use up. Thank you.


Doug

That would be the best source a going as far as I know. I take data from there and then cross reference from a good burn rate chart, like this one. http://www.lapua.com/upload/reloadin...echart2011.pdf

Start a grain or so off and work up.

Alliant does show 9.0 gr of PP with the .40 S&W using 155 gr GDHP, albeit a max load. Given the 10mm's larger case volume , and your using a slightly lighter bullet weight, your 9.7 gr 'should' be workable, but I dislike 'guessing'. (It seems as though Alliant simply didn't bother with PP for the 10mm for some unknown reason.

Are you positive PP is a suitable 10mm powder, the reason I ask is lack of punlished data. I don't like guessing either, I value my pistols and fingers.

My bad Hornady #8 shows Power Pistol loads for their 155 gr XTP's starting at 8.4 max 10.0 1.260 COL WLP primers.

If the link works there is a ton of 10mm loads there.

They say PP is a good powder for the 10mm I just can't find data for the 150's I can for other weights though.

My Modern Reloading 2nd Edition lists a 150gr jacketed bullet 9.0-9.7gr of PP @ 1.250" OAL. It doesnt list a JHP.

Yes the Power Pistol can be used successfully in the 10MM

Is there some urgency or special need regarding what appears to be suggested as a maximum or near maximum charge weight?

Is there a race or some contest involved we are not aware of?

If you just took the time to perform even the shortest of work ups (5 – 8 cases) you could solve this for yourself.
(5 – 8 (preferably 10 as a minimum) per charge weight “work up”)

Make five to eight starting at 8.7 - 9.0grs and work them up in two or three grain increments
When you get close to the ~ 9.5gr. area maybe increase in one grain increments.

If I had the powder, cases, primers and the bullets it would take me all of fifteen minutes to make this little group up.

I don’t know about your guns but I have guns that reach there “maximum” before many of the published maximums depending on the bullet and loading I’m working with.

How the hell can we tell if 9.7 is safe in your gun with your brass using your scale etc.etc.
Only the work up can tell you this.

I or some other idiot can tell you it’s fine because they use 9.9grs. or even 10.1grs.
It makes no difference without the work up

Good Luck

SDMC, your welcome.
OP Gerk is 1000% percent correct you've got to do a proper work up

Use some caution with this (and any other internet) data.
I glanced over only two pages and found errors in the presenation.

Don’t assume that because the compilation “looks” right that it is.

ALWAYS base your loading decisions on “known reliable” sources.
(As in published developers data as your primary source)

Good Luck

Oh, absolutely Gerk. I see my load in there and I think their performance is a little under rated/under stated according to my personal experience. But I wouldn't make the same assumption for every, or anything in there. But there are a lot of possibilities in there. Start off a grain and work up is my motto.

One other thing re-loaders for the 10mm in the Delta Elite should do is measure the base expansion of the brass. This where over pressure signs for your weapon that are less conventional, can show up. Bulges at the base can happen exponentially from a few tenths of a grain

Contact Alliant and ask them. They sent me a nice little PDF with the information I was looking for.

I will try that route. I was thinking about that earlier but forgot when I noticed I was running late for work. Thanks.

10-4….
But you know the rule on data

Junk in….equals junk out

Excellent point you raised regarding the unsupported barrel loading aspect of (Delta Elite, etc) guns by the way.
The full (and safe) 10MM experience can only be realized in supported fully ramped barrels.
Attempting this in unsupported barrel guns can lead to more than “disappointment” quickly.

(Colt should have rectified this when they reissued the gun a few years ago)

Good Luck

I received an email back from Alliant Powder. They said for my load in the 10mm with power pistol and 150 grain sierra hollow point. Starting point would be 8.5 grains to 10 grains to be close to max. Just thought I would share.
