Have a friend who loaded some 180 Scirocco's in his 30-378 Weatherby super banger. He will probably never use anything else. He took an elk at an unreal distance last year, much further than anyone should be shotting at one, and he loved the performance. I think the BC should be a little higher than the Ballistic Tips because of less lead content and heavier jacket, hence a longer bullet for the weight. I plan on loading these in my 300 Winchester Mag as an all purpose load. I am hoping the sturdier construction will produce minimal meat damage on whitetails at all ranges.
