Somewhere along the line I was gifted a pile of 416 bullets, 300, 350 and 400 grains IIRC. I enjoy shooting my 375 H&H and the 416 with reduced loads of AA5744 and will continue to do so. I got the wondering if anyone has tried BP substitutes. My 375 will shoot good groups with 5744 and the 416 is as good as most 30-30's. Finding reduced loads is easy but what about a a 416 smokey joe???? TYIA
