with apparently similar specifications. For

clay training and teaching, no one needs
more than 24gmin a 12-bore (21gm and
24gmworkwellina 20).
Finally, what about all the anti-recoil
gizmos? Hundreds have been marketed.
Muzzlebrakesandbarrelportingwereonce
infashion.Mercuryandmechanical‘recoil’
reducers may still be seen.You mayalso
encounter hydraulic,sprung orpneumatic
shockabsorbers,andpaddedorrubberised
cheekpieces(quitecommononoldguns).
Someofthesehavelittlerealeffect,some
arebetterproven(theIsissystemhasa lot
of fans amongst competitionshots). I am
notgenerallyanadvocateofgizmos;a well-
chosen, well-fitted gun and sound basic
technique will sort most women’s recoil
issues. The modern polymer pads work
well,asnoted,andsimilarmaterialmaybe

recoil. Available in all bore sizes, they may be

admirablysuitableforfemaleshotsbutare
not normally welcome on a driven shoot.

THESCIENCEOFRECOIL

fromthephysiqueoftheshooter,thatneed
tobetakenintoconsiderationincludegun
weight,muzzlevelocity,operatingpressure,
projectile mass and bore size. Recoil has
twophases.Thefirst,calledprimaryrecoil,

There is also upwards rotation during
recoil because the bore axis isabove the
shoulderline.It maycausethecombtocome

oftenhavehighercheekbonesthanmen, so
these considerations become critical.
