Yes, I remember those pics, Ron. I have the entire series, and need to get them out and reread them all this winter to refresh my memory. I had some correspondence back then with Bell, by letter, and he always impressed me as being both thorough and courteous. I should reread those letters at the same time.

My example of using bismuth in lead data published data 22.5 gr 800x 1oz shot AA hull w209 p 1215 FPS 6500 Lup. Load number 2 22.5 800x 1 1/8 oz shot waa12 wad 1200fps 7100 lup I put 1 oz bismuth in the 2 nd load the waa 12 wad accommodates the 15 percent increase in volume which is about 9 pellets the crimp is perfect. I may be playing with danger ,I have been shooting this load for decades , very soft recoil. Disclaimer this is my personal load and I certainly do not suggest that anyone uses this data . Just adding to the mix . Thanks don
