12 bore Round Action over and under, colour hardened

The colour hardened round action over and under is the unification of new and old epitomising Boxall and Edmiston as a company, our ethos and aims. The modern engineering of the round action over and under, its design and engineering, is combined with the beauty and art of the colour case hardening, reminiscent of British guns of old.

The gun has a classic trigger plate lockwork system. This system is central to the action allowing maximum impact of the main (leaf) springs force as it pushes the hammer into the striker. Furthermore, the central location of the lockwork allows minimal striker angle through the action body to the breech face which delivers the cartridge detonation more efficiently as it hits the detonator almost straight on.

The colour hardening process was carried out by some of the British gun trades finest colour hardeners and one of the oldest family businesses engaged in the gun trade today, who work with Holland and Holland, Boss and Co. and Purdeys to name but a few. The colour case hardened model is an aesthetic change to the round action over and under.

The use of leaf springs, a must on classic British guns, gives a faster detonation time as it’s energy can be released more efficiently as it is uncompressed as the sear releases the hammer.
