A lot of sambar have been shot with the 303 over the years.
I used a martini 303 loaded with 215 gn woodleigh's last year in the NT with brilliant results.
Half grown buff one shot kill.
Front on shot on pig also cleaned up its mate standing behind it..
Woodleigh gave me a load which is as follows:-
303 win brass,fed primer,39gns 2208,215 gn woodleigh projectile,overall length 3.05 ins
I have shot a lot of scrub cattle over the years with a 303 and seldom ever had to deliver a finishing shot.
