Big Jim 300 for me.
Thing is, I've nver had real trouble with penetration. I did shoot a big grizzly one year, and it did the job fine, in the dirt on the other side like they say. So did the eclipse, zwickey and stinger.
Then again, so were the razorcaps several years back, the VPA the last year, and woodsmans several times.
I've decided that any broadhead will do, flying straight and shasp.
SO, I shoot EFOC with heavy (800 grain) arrows and the biggest nightmare on elm street broadhead I can trust.
That would be a Big Jim 300. If it only barely pokes its head out, our stays in there cutting, or blows there to other parts of the world, so be it. Dead elk eith way.
