I can only mention of experience in five species of deer that have been taken under my aim and do agree that Sambar are as tenacious as anything.

eagle27 as you probably know, earlier in the thread i wrote the below.

As most members would know I have been touting factory Win 150 or 175 Sp`s forever,yes I have used Hydros/Partitions/round nose and whatever else that I cant remember. Gee they work extremely well in 7mmrm format.
I dont know why they dont work as well (presuming its the same projectile?) in the `57.Perhaps its the lesser power of the `57 I suspect.

About a week ago I took my summer meat.I used my 7mmrm with a 150 Win SP and it was a DOTS deer.Bang! DEAD! Shot through the shoulder at 150 yards I reckon.

Emphatic! And a deer that believe or not probably went well over 500 lbs,his arse end cut off at the last rib and hocked went 150lbs,his miserable head and neck a further 68lbs.His front end I didnt weigh.
His arse realised 30 kilos of mince plus the scotches and the eye fillets.
He was the smallest of the three stags and I initially thought he was a big spikey but he is prob a three yr old.

Anyway I`m very happy to use the Win ammo as outlined above.
