New Goex Pinnacle

[Howdy Doody]

I tried out five pounds and used it all up. I just got a 12 pound case. I really like this stuff. I am shooting the 2f in pistol and rifle cartridge and C&B. This stuff smokes and is smooth. No flames, but everything else you could want. Cleanup is a breeze.
I know it is made in conjuntion with APP, but it is different. No clumps in one pound jars, black colored, does not seem to be as hydroscopic as APP. Price about the same as APP.
I tried it as half a 10 pound case and I am using the other 5 lbs of Cowboy for shotgun loads.
Who else has any reports on this new product?

I got a  pound at EOT . used it in my Cap and Ball pistols. I did like it , although in the SUPER HOT desert I found it to gain in power and recoil as the day got hotter. Remember it is not uncomon to reach 110 here. Not a problem in most pistols but I am shooting Brass frames right now and down want the extra power.

I do like the powder and its ease of cleaning up.

I would give it a thumbs up


Just my $ 0.02  worth

That is interesting Mason. I didn't take chemistry in school and don't know why that would happen to gain power like that, but if you saw the video of me shooting W3G then you can see that my 30gr loads were giving me a good recoil in heavy ROAs. It was hot there too, about 100. I didn't notice it when I was shooting, but the video of me dumping on a 5 round dump looks kind of hairy. Good observation pard, I will check that out when the weather around here starts to warm up again. 30gr sure gave the effect of a lot bigger charge I thought when viewing. While shooting, I don't notice anything. Too much concentration on trying to see and hit the target I suppose.

The chemisty behind the kind of performance Mason reports is that chemical reactions commonly happen faster at higher temperatures. One sees the opposite behavior with some powders that get really wimpy, even giving squibs, in cold weather when loaded too lightly. I have never heard or read anything about any vaiability in power of Pinnicle with temperature. All powders have it to some degree. Many of us have cold weather loads and hot weather loads for just this reason -- sometimes one finds that cold weather loads generate too much chamber pressure in really hot weather. There have been reports that some commercial premium ammo for big, high pressure cartridges produce too much pressure when used in Africa during really hot weather.

Thanks Lars,
I didn't realize that was so noticable in weather changes. I shoot in pretty even temps usually. Lows probably 50s and highs at 100. I just always load 30grs of anything except of course 777. I had been shooting the Goex Cowboy for a year, but I like this Pinnacle so much that I am going to shoot it for a while. I like the clean cylinder face and easy clean up a lot.
Lars, what you say makes a lot of sense. If I ever shoot in really cold weather or really hot weather I will keep the information in mind. I usually just like a breeze

Glad to hear about the powder.  I saw some in a gun shop that is a bit out of the way that I only stop by one every few months.  I bought a pound to see what it might do.  Figured I couldn't go too wrong given that it was from Goex.

Howdy!

When I was in Master Gunner school, we learned that generally, powders stored in hot conditions (over 70 deg. F, which is the optimum) for longer than normal time periods did get hotter.  The computer in the M1 series tanks (M1, M1IP, M1A1, & M1A2) has an input for ammo temps.  It compensates for this in the ballistic solution that puts the superelevation on the gun.  (And yes, the correct term IS gun when referring to US tanks.)  This point was re-enforced to me personally when I got home and started using a pound of Hercules (now Alliant) Bullseye that my buddy had stored for me in his garage while I was stationed in W. Germany.  That powder was indeed hotter, tho it had not deteriorated:  I just used about .5 gr. less powder than normal. 

As Lars and others stated, cold temps can also affect the performance of many powders, (some a bit, some much more) but it was a temporary change, not permanent, like the Bullseye was affected.
