My .375 fly at 2.950 fts. with this bullet and impact in less of 1" at 150 Meters. Excellent performance, buy I never hunted with this bullet. I think in Red Deer (200 / 250 kgs.) in the mountains of the south of my country.
I appreciate any hunting experience with Sierra 250 BT.
I'm sorry for my bud English.
Best Regards for all and my best wish for the new year!

Hector,
Your english is one hell of a lot better than my Spanish. Unfortunately, I have not used the 250 Sierra. Your load seems fast, and because Sierra is not noted for particularly stout bullets, I'd be concerned about it holding together. However, that said, if it were at a distance, I'd not worry about it.

You may want to check Sierra's web site and see if they publish any operating ranges for the bullet. You can plug in your starting velocity and see how much it has dropped at 200 and 300 meters. This will tell you if you are too fast. Kudude

Ask this question on the Big Bores section and you will get plenty of help there.
Good Luck

I have taken eland, impala and wildebeest with the 250 sierra bt in 375. I would recomend slowing the bullet down to about 2400 - I seem to get best performance and expansion at that speed. On all the animals where I have recovered the bullet - at these speeds - I have had excellent weight retention and expansion. On a fully grown bull eland weighing in at around 750kg's the sierra knocked the animal flat with a heart lung shot. Kudude is correct, the bullet may have trouble holding together at 2900.
