Matt, these are some federal hulls I bought from BP that were primed. They have no marking except for headstamps. My goal is to find several combinations with a single powder (which I have a fair amount of) that work well and keep me in the same range on velocity and pressure. Component availability being what it is I figure it better to have more workable combinations and am "hunting" that 7500 psi area, certainly under 8K. Easy on aged guns and aging duck hunters!
I am also a student of the school that says the more consistent the velocity of the loads you shoot across all guns/gauges the better a shot you will be. Leads won't change. I want all to be in the 1250-1275 range making lead calculation the same whether I'm shooting doves, upland, clays, or waterfowl. Constantly changing velocities from one field to another can't help with consistent good shooting. It also appears from my efforts on the pattern board (butcher paper on a barb wire fence) I see patterns more consistent in slower velocity ammo. My average on long, second shot birds has definitely gone up following this train of thought. Doubt it makes much difference on the first bird over decoys, you're shooting him in the face at 20 - 25 yards as he settles. That second bird is winging it for all he's worth often out at 45 to 50 yards.
