Parker Blow Up

[Harry Collins]

Thanks Drew, The VH belongs to me and I've resurrected it with Damascus barrels that had belonged to my fathers first cousins,

Bell tested 2 10g Parkers; with 2 5/8” and 2 7/8” chambers, using 3 1/2” Proof loads at 19,840 PSI. Neither of barrels showed any dimensional changes even with the long shell in short chambers.

That's crazy

[Drew Hause]

On the topic of crazy, in the Birmingham Proof House Trial reported in 1891, the five barrels tied in the 2nd Phase failed at 12.5 times the Definitive Proof load or 11.34 Drams with 2.82 oz. shot. That is in the range of 140,000 psi

The Trial is reviewed about 1/3 down here
