pyordex and triple 7

[robm1093]

I shot 150gr pyorde but the gun shop onley had triple 7 so I got sum. If i go with the triple 7, 150gr will my accuracy be the same? I do have sum pyordex but it's one or two years old.

No telling without shooting. Try 135gr of the T7 if you want velocities roughly comparable to your pyrodex.

120gr T7 2f = 150gr pyrodex RS-select 2f.

depends on if your using loose powder or pellets...if using powder reduce powder by i think 13% maybe its 15%...if your using pellets theres no difference between brands, so no need to reduce, drop in three 50grain pellets.

If you are shooting 150 grains of Pyro Pellets, then 150 grains of T7 pellets is roughly the same.

If you are shooting 150 grains of LOOSE Pyro, then 120grains of T7-2f should be close to the Pyro load.

If your Pyro has been sealed with the lid tightly it will probably be just fine.

Thanks. I am shoting pellets.

Probably not the same, you can get the same velocity but the potential energy and burning rate of the powders are different that changes two things the position of the bullet will be closer to the breach plug because 777 has more energy in less volume and since the burning rate is different the whip or vibration of the barrel is different.
So literally impossible to predict the difference or how much, best plan on sighting it in. Lee

No time to sight in. I will be hunting in the am. I have two ryordex loads that wer in the plastik speed loaders. I am thinking theys should be good. Or mabey I should just try the triple 7 and hope for the best..........

I think I will go with the one year old pyordex pellets with new 209 primer. The pellets wer in a closed box. in the past I have had delyed ignishon is this do to the primer or the pellets?

Hmmm, I guess it could be a combo of old powder and a weak primmer, but would lean more toward's a dirty breech plug. Get all the carbon build-up out of the flash hole with a drill bit, and clean out the little hole w/a bread wrapper tie. Just burn the plastic end off an run the wire thru a few times. This should help it egnite faster.
