T7 3pellets or pyro3 pellets chrongraph tests?
 

Has anyone tested 3t7 pellets out of a chrongraph and 3 pyro pellets to see the difference in the ballistics, I'd like to see the results cuase I hear that t7 pellets are not the same power as t7 powder, and I would like to try them. I use 3 pyro pellets with 240PR deadcenter and this year I have had very good results with this combo, using an encore .50 cal with a muzzle brake on it, definitly helps with the recoil like shooting only 2 pellets.

Yes,I did.
With 150 grains of each(pellets) and 240 grn XTP bullets out of a 700 ML Remington,it shot 2246 with 777 and 2218 with the pyrodex.But the 77 was having bad hangfires,so I'm sticking with the pyrodex.

Eb, as you recall, I also had the "double-bang" or "hang-fire" problem with the T7 in my Remington 700 smoker, but for the record, I tried the Trip 7 in my TC Encore 209x50 ml rifle and the stuff worked fine.

Boy, this is interesting!! WORSE ignition with 777 than Pyrodex?? WOW! Just the opposite of what I would have expected! Guess I'll still stick with loose powder!! (No improvement in ballistics either, I see!!)

It would also be interesting to conduct the same tests using loose powder. Due to safety reasons, we would not want anyone loading 150 grains of loose Triple Se7en in the rifles, but perhaps 120 grains of each and then do a load of 150 grains of Pyrodex to see if there is any real advantage to the powders being tested.

Hodgdon purposely "toned down" the strength of the T7 pellets to closely approximate the Pyrodex variety. I think their purpose was safety as well as making the transition easier for pellet shooters. Figure the cost of a weighed pound of either powder's pellets vs loose powder and, after you pick yourself up, go buy some loose. :)

Loose powder comparisons will yield a different result - considerably different. T7 is much more potent and will deliver significant velocity gains for equal volumetric loads of similar granulations.

For the sake of your shoulders, I would suggest no more than 100 grains of loose powder for any tests.

T7 has its pluses in that cleanup is a bit easier and it is more energetic but the hardness of the fouling and the problems that creates make good ol' Pyrodex a better choice for lots of uses.

I suppose both of you guys are using the Remington 209 conversions??????

If you are, then I suggest buying the ones from Cabelas. They are designed different & the 777 hangfires will disappear. Lots of complaints about the Remington conversion kit... they're not designed to fuel enough fire to ignite 777... which needs a higher temperature than Pyro and Black.

Yep,that was with the remington 209 converstion.I'll probably try that cabelas nipple for next year,because the cleanup with the 777 would be well worth the switch.
