Kynoch (Kynamco) .303 MkVII Ammunition

[Alan de Enfield]

With all the talk about key-holing, boat tail bullets, MKVII and MkVIII ammunition I thought I'd do a little investigation into the 'new' (recently made) Kynamco MkVII ammunition.

Powder charge = 39.3 grns
Case = S&B
Bullet = 174 gr R.O
Primer = Boxer
Velocity (Muzzle) 2489 ft/sec
Velocity (at 100 mts) 2406 ft/sec
Energy (Muzzle) 2400 ft/lbs
Energy (at 100mts) 2238 ft/lbs

Bullet length = 1.286"
Bullet diameter 0.311"
Case rim thickness = 0.058" - 0.060"

Not a boat-tail bullet (with the 0.311 being at the base)
