Needless to say powder's been tough to find locally, so I'm trying to make do with what I have on hand, which like he title says is IMR4320. I'd just like to get some opinions before I go out shooting an unfamiliar load. Here's what I've got:
Shooting an AR type rifle, 20" 1-9 barrel. Using Hornady 55 gr. fmj with canalure, seated to OAL of 2.200
I have 4 loads starting at 23.5gr working up to 25, in half gr increments, using a combination of info from both Hornady and Hogdon manuals.
The OAL of 2.200 puts the canalure completely beneath the case mouth. I know that in itself won't hurt anything, but find it strange that Hornady made the bullets, and recommends a seating depth that far off the canalure. On the other hand, they do fit well in the magazine, where a dummy seated to the middle of the canalure is really tight.
The 25 gr load fills the case to the bottom of the neck, so I'm going to proceed cautiously, and inspect the other cases for signs of pressure before I fire the max load.
Any experiences with this combination, or advice and opinions would be appreciated. I won't be headed to the range for about a week, so I've got time to change things if need be. Thanks guys.
