Hello,
I recorded the following results for my second series Warrior and ABAS Major pistols during a 10 shot string .
Pellet H&N Pistol Match Wadcutter Wt= 7.56 grns.
Warrior
Average Muzzle Velocity = 350 fps Muzzle Energy = 2.05 ft/lbs
ABAS Major
Average Muzzle Velocity = 410 fps Muzzle Energy = 2.8 ft/lbs
Both pistols are in good functional condition, are fitted with all original parts and punch nicely grouped, clean holes in the card at 10 metres.
The above values compare with average muzzle energy results from my Webley Premier / Senior / Mk1 of about 3ft/lbs.
Hope this helps.
Regards
Brian
