Single-shot spread with sniper range.

Single-shot spread with sniper range.
- dasm 8y agoUnfortunately, aligning different bores is very difficult. Putting them in the same chunk of steel prevents them from diverging over time, at least, but doesn't solve the original issue.
- qbrass 8y agoThey'll diverge as the gun heats up and the inner bores stay hotter than the outer ones. Both short term as you use the gun and the barrel warms up, and long term, when the bores wear differently for the same reason.
- dasm 8y agoGood point! Hadn't thought about the bore wear - if they don't force successive shots to cycle through the barrels, that would be a huge issue.
- paulddraper 8y agoMaybe. I'm skeptical that multiple simultaneous discharges wouldn't adversely affect the accuracy.
- dasm 8y agoThis is way too detailed, but describes how barrels behave while a shot is being fired: http://www.the-long-family.com/shock%20wave%20theory%20summary%20explanation.pdf http://www.the-long-family.com/shock%20wave%20theory%20summa... Based on this, it seems like multiple barrels probably wouldn't affect each other in different ways, leading to shot consistency as long as there aren't significant differences in ignition time or velocity.
- dasm 8y agoAlmost forgot: while not simultaneous, the AN-94 did not have issues with ultra-fast RPM in one barrel (https://en.wikipedia.org/wiki/AN-94 https://en.wikipedia.org/wiki/AN-94).
