I understand this may be different in certain rifles... what is the original Kynoch ammo bullet diameter and did different British makers also offer their own ammunition to go in rifles so chambered to fit the slight changes in bullet diameter? I have seen Westley Richards proprietary loadings for the caliber and Kynoch, any other houses load for it? On the plains of hesitation lie the bleached bones of ten thousand, who on the dawn of victory lay down their weary heads resting, and there resting, died. If you can talk with crowds and keep your virtue, Or walk with Kings - nor lose the common touch... Yours is the Earth and everything that's in it, And - which is more - you'll be a Man, my son! - Rudyard Kipling Life grows grim without senseless indulgence. | ||

On the 3 1/4" case I have pesonally seen diameters form .408 to .410. I have heard as small as .406.

I have a box of original Kynoch 450/400 3.25 but don't want to pull one apart to measure. I suspect somewhere that info is on a forum. On my Webley built William Evans 450/400 3.25 from the 1920s the bores measured .408. | |||

They used some tapered bullets way back as well, to keep pressure down so only the heel might be at full groove diameter. | |||

I have slugged the 6 that I have or currently own. The BPE Rigbys are .408 and my Nitro run .410 on average with one barrel .411 on an early A&N while the other barrel was .410. | |||

I had a few boxes of old Kynoch 3"years ago. Shot most up chronoing it (1950-2025fps but barrels grouped well, topic for another time) and pulled, measured, weighed, and reloaded a few. Most were .4105" and that only at the base. Complete speculation on my part but that probably would be a good way to compensate for varying bore diameters amongst rifle makers and also likely kept pressure down, especially with solids. Those guys were really, really, good at what they did!  Bob DRSS "If we're not supposed to eat animals, why are they made out of meat?" "PS. To add a bit of Pappasonian philosophy: this single barrel stuff is just a passing fad. Bolt actions and single shots will fade away as did disco, the hula hoop, and bell-bottomed pants. Doubles will rule the world!" | |||

Interesting. I will check my ammunition if they are the same. | |||
