I've hunted elk and whitetail with Freedom Arms 475 Linebaugh, limiting my shot to 35 yards. This really isn't much of a limitation because I was hunting in extremely thick woods. I got no shots, and the Model 83 was sold. I have access to a T/C 454 Casull with 7.5-inch barrel, 2X scope, and "hunting" bipod. Since I consider this combination to really be a short rifle, I want to extend my limit to 135-165 yards.
Using hard cast 300-grain Saeco (#058, 454 SWC-GC) bullet that leaves the barrel at 1400-1550 ft/sec, how high is the confidence level that this bullet will penetrate "through-and-through" on elk - including one shoulder - at 135 yards? At 165 yards?
