Lets not discuss techniques used between the two(neck tension/ shoulder set back), but the actually firing method used.
I know some people prefer the optimal charge weight test.
Some prefer ladder tests.
While others like finding the velocity nodes/flat spots in a span of 10-20 different powder charges.
What affect can a gas system have on velocity and finding that velocity sweet spot?
I normally looking for a velocity node in my bolt gun reloading. Which tends to work reliably for everything I have done.
Never have actually tried getting a constant velocity load worked for a semi auto.
