Hi,
I'm going black bear hunting in a month and I'm going to be using my Husky 8x57. I have Sierra 200 gr Pro-Hunter and Speer 175 gr Hot Cor soft point bullets to reload using PPU brass.
I've only shot the 198 gr FMJ Prvi in this rifle and it was dead on using the factory irons, and I was hitting the gong at 200 meters if I did my part. I want to mimic this FMJ performance using a soft point hunting bullet.
Firstly, if I used the Sierra 200 gr bullets, anybody know what kind of powder would give similar performance to the 200 gr Prvi ammo?
This is Prvi's data: 8 mm Mauser FMJ BT 198gr;665m/s; 2840J; 610mm barrel length tested
Secondly, will 200 gr SP penetrate and expand enough to kill a black bear without it running off? I suppose I'm asking, will it transfer enough kinetic energy while breaking bone and tissue to basically drop it?
The other option I have is a 150 gr 30-30 Marlin but I don't want to risk being underpowered. I have some 170 gr Rem Cor-Lokts as well, but my rifle is sighted in using the 150gr, do you think POA and POI will vary significantly as 100 yards?
Thanks!
P.S. How long are the usual engagements with black bears?
