This is a Barnes 300gr TSX recovered from a Blue Wildebeest shot at approximately a 100m. The ammunition was reloaded by a mate of mine.

The BW was facing me and the shot was into the centre of his chest. It was later recovered next to his tail after penetrating the full length of the animal. I was disappointed with the performance of the bullet as the expansion was poor in my opinion.

I later pulled the heads of a couple of rounds and checked the powder weight. I discovered that the ammunition was under loaded to the extent that it was just under the recommended minimum starting load.

I surmise that the muzzle velocity was under 2100 f/ps and the impact velocity was probably under 2000 f/ps. The Barnes bullet still showed some expansion despite the low impact velocity, the penetration was outstanding!

Yes your muzzle velocity is quite low! Barnes factory 300 TSX ammo in my MRC is 2,529 fps. My handloads are over 2,600 fps. Velocity with monolithic bullets is critical.

I bought some bullets from Rimshot and he is good to trade with!
Greetings all! I've been a hunter for 50 years, but only now planning a trip to Africa. I was fortunate and successfully bid on a couple hunts for plains game in SA later this year and next. Also a rare Native Texas (5th generation) and USMC Vet. Hunt safe y'all!

I am looking for a Safari Express. Was yours made in New Haven or South Carolina? Any other details you can give me? I am very motivated to buy.
