I ran side-by-side, rainy weather, all day long tests with APP and 777. That is how I reached my primer recommendations in my earlier post.

With three jugs of each powder (777-APP)that I used in three different tests using one jug of each for every test, I first tested these powders with the lids off& granules exposed to damp air- both driver & pasenger doors open-- jugs sitting on on my pickup centerconsoleduring a four hour light rain.

The next day with the same light rain & temps around 45-50 degrees, I loaded both guns with both powders & laid both rifles under a fully sheltered tree with muzzle upfor another four hours.

The 3rd day, I tested both powders taking them in & out of heated vehicles - back out to the elements - even into the cabin for an hour.

So that's how I derived that hotter primers may someday become a must to have in damp conditions with APP... even777.

My tests concluded 777 lasted longer without a hang/misfire ... but not significantly longer.

Idespise discussing anything withyou Mr. American Pioneer -- even though I like your powder - once I learned to how to properly use it. I shouldn't even had said this much to you -- in defense of my earlierpost.

How I reached the conclusions of my tests will not be available to you - only because of your poor attitude on what was written here before you arrived & read it.

You simply are notworth the explanation of my tests -- due to run-in's with you in the past.
See Ya.
