A study by the Royal Military College of Science, sponsored by the Birmingham Proof House and the British Association for Shooting and Conservation, showed that an obstruction by 2 fibre wads (total weight of 4 grams) was sufficient to bulge or burst a 12 gauge barrel shooting a 28 gram (slightly less than 1 ounce) load. Peak pressure occurred 22mm (.866”) past the leading edge of the obstruction.
Any value for said pressure?
I'll bet a military ordnance engineer might have an answer. Don't you have any PhD buddies up in Huntsville who could help?
I do such as the >>Rocket City Rednecks<<. But we always preferred non-destructive testing. @ one point in grad school we didn't submit a proposal for non-destructive testing of prophylactics. Can't recall if it was the Government, Trojan or who???
