I have used the Taipan 300 grain SP in my .375. I have shot a few pigs with this bullet and they were dead before they hit the ground. All pigs had minimal meat damage with small exit wounds.
My brother has used the Taipan 150 grain HP in his 30/06. He has shot many goats and roos out to 300 yards. These bullets hit hard and left massive exit wounds.
In my opinion they are a good cheap bullet and have always performed well and accuratly.
If you are planning on hunting elk or moose with the .303 the Woodleigh 215 grain RN would be a better choice.
