My Guide gun shoot the 300 gr Sierra HP well and with good results. My load is 51 gr of H4198. I've taken 3 black bear with this load with as many shots. For the larger bears though, I would go with a FP and/or a heavier bullet like a 405 gr hard cast.
Thats a hefty load. I got horrible results and still do with 51gr. Only can go up to 46gr. But still getting 1950fps or more with 300gr.
Thinking of getting a new guide gun and trying.
