To address the "solution" part of your query . . .
I was concerned that the second barrel's projectile from my Kodiak Safari .72-caliber rifle would be recoil-jarred to a dangerous position. Here's what I did.
1. Ruled out patched RBs as being too easy to move with heavy loads.
2. Bought a custom conical bullet mold. Mold drops 775-grain bullets @ 30:1. Three driving bands and two lube grooves, driving bands [from base to point] ascend their diameters. Bullets are pan lubed with SPG. Bullets are mallet loaded.
3. To verify bullets were not moving from recoil - or, for that matter, from magic spells - I loaded left/second barrel then I and a friend fired 20 full power shots from the right barrel. After every shot I checked for left barrel's bullet movement with marked rod. No movement. The following week we did the same, reversing barrel tested. No movement.
4. After verification process, I adjusted propellant charge downward and regulated the barrels.
5. When hunting from the ground, I take my short starter, mallet, and stainless steel loading rod kind've stuffed into my belt. Although I have not yet reloaded in the field, from my range experience, it would be a five-minute job - that is, no possibility that a third shot would be at an animal I missed with the first two.
Hope this helps.
