I ran across this tonight, and it appears to be a fabulous resource.... ... ojectiles/

It has over 3900 bullets, including many cast bullets.... You can access the data by caliber, and sort by manufacturer, weight, length, or other factors.... It gives the Sectional Density (SD), and the Ballistics Coefficient (I assume G1) at different velocities (if known).... As an example, here are the results for the popular Lyman 257420....

SD = 0.148
BC above 2200 fps = 0.129
BC above 1800 fps = 0.152
BC above 1300 fps = 0.18
BC above 800 fps = 0.20
BC below 800 fps = 0.15

I have only just begun to explore this database, but wanted to share it with all of you....

Too many! Springers, Pumpers, CO2, but I love my PCPs and developing them!
