I hope one day in the next few years to purchase my first double rifle. I have pretty much decided on a 450/400 Chapius but I occasionally see a vintage British 450/400NE 3in in a similar price range of the Chapius. My question for everyone is if you don't reload your own ammunition, does factory specifically Hornady ammo tend (emphasis on tend) to regulate decent in older British 450/400s? Thoughts?
