Maybe this..........
What does putting your scap in your back pocket mean?
Why are we forcing a scap load anyway? Launch the barrel and feel the scap retract on its own...All of this FORCED MOVEMENT! Long and slow!
Can you clarify what's launching the barrel? What happens during launch that causes the scap to retract on its own? Is it retracting from a relaxed / static position, or was it stretched / extended by something pre-launch?
I've always viewed it as a conscious (deliberate?) movement, are you saying it's more of a byproduct of other movements?
