Pyrodex P ,Ignition and Velocity from Remington New Army ??
« on: December 16, 2019, 05:04:03 PM »
For those who use Pyrodex P does it give good ignition without Hangfires?
If you have a chronograph what is the velocity you are getting with a 30 to 40 grain charge behind a round ball ?

Same 2 Questions for Straight Triple 7 with no booster charge.

Below are some Pyro P stats from Pocono Shooting using .44 Remingtons.   Last time I got crony results was using a Pietta .44 Remington and Pyrodex P.  My average was around 950 fps with .454’s using 30 grains.  That seems to be a bit faster than what most folks clock.

For the longest time Pyrodex was the only available powder in my area so I’ve shot a lot of that stuff.  I’ve never had ignition problems using it.  Even in paper carts it has always ignited just fine for me.

Triple 7 is hot.  Penetration test on pine planks indicate that it produces significantly increased velocities over Pyrodex - grain for grain, volumetric.  Generally, I follow the 15% advisory just to be safe.  No ignition problems whatever.

Never used T7, but I've shot a ton of Pyro P due to availability.
Only time I've had issues was when shooting up the remainder of a pound that was at least 4 years old and had been opened that long. Kind of weak and lethargic. I dumped it out and opened a fresh pound and the difference was striking.
Also, Pyro P really likes the NEW #10 Remington caps (the hot ones).

I've used a lot of Pyrodex since it first came out. I mostly use RS(even in revolvers)since it's easier to find. I've never had any issues using standard caps on side locks and revolvers. It's good in cartridges too. I did have slow fires with my 63 Sharps because of the long firing channel with two turns but it never failed to fire. It was kinda like a poorly timed flintlock. It cleans up just as easily as real bp and I sometimes go several days without cleaning after using it. It's also the cheapest of all the subs and because it's lighter than bp and measured by volume you get more shots per pound.

Good to know that neither the Pyrodex P or the Triple 7 have ignition problems.

That is an interesting link
It Looks like it will be relatively easy to get 900 FPS with The Pietta Sheriff 5 -1/2 barrel I have  Along with the Hornady .454 balls I have.

Thanks

Good Information,Hard to tell right now but I think I will go through a Pound in 6 months or so.
I bought a 100 of the hotter Remington Caps the other day when I stopped by the store.
I bought just the Primers as I did not want to by any powder till I was sure what Kind I wanted .

When I go by the store next week I will pickup a pound of the Pyrodex P

Thanks

That is good,I had not even thought about using the RS,Good to know if I ever have an Issue finding the Pyrodex P
Good to know also about the cleanup and getting more shots per pound,that works for me !
Solves my issue of which powder to use ,cheap,More shots per pound and good ignition,available locally.

Thanks

I know there are 7000 grains per pound so dividing 7000 grains by 30 grains would be about 233 shots using Black Powder

What is the formula to reflect  the difference in amount of shots with Pyrodex P ?

This material from ssb73q may pertain and help solve the various differences in volume to weight.  He’s established the relative weights of some of the good stuff.    Pyrodex P when thrown from his 30 grain (volumetric) spout weighed an actual 18.2 grains.

Then it looks like using the Pyrodex P would result in about 384 shots per pound compared to using Black powder resulting in about 233 shots per pound ,both when using 30 Grains measured by volume.
Pretty Big Difference
