Hello Tom Leoni,
Beauty !
Yours truly once owned the Army & Navy hammer gun shown in my Avatar.
Mine was a .450 No2 NE.
The 28” barrels would put 4 shots (480 grainers, 2 softs & 2 solids) inside 2” @ 50 meters, easy breezy.
I couldn’t help but notice that, when hunting with it, if I shot it straight, then reloading it quickly was not necessary, LoL.
I suspect mine was made for A&N by J. Manton, because I once saw an identical rifle to mine except in caliber .470 NE and marked by that maker (no A&N markings like mine).
Sadly, being of modest income, I had to sell it to pay my safari bill, when I returned home from a combination Buffalo and so called Plains Game hunting trip.
I can either have a tall stack of guns or, I can go hunting in Africa now and then.
I choose Africa.
Anyway, man like the other fellows here, I am way impressed with your new rifle.
And, I look forward to you posting information on how it shoots.
Hopefully there will also be stories and photos of hunting with it as well.
I repeat … Beauty !
Best Regards,
Paul
