Re: For The Ballistic Gurus A ?

See if these numbers make any sense:

357-- Federal Nyclad 158grn--1110fps = 432 fpe

Winchester Silvertips 145grn--1187 fps = 453 fpe

Hornady XTP 125grn--1196 fps = 397 fpe


44-- Winchester Silver Tip 210grn--1039fps = 503 fpe

PMV Starfire 240grn--1022fps = 556 fpe

CCI Blazer--240grn--903fps = 434 fpe


I figured these using a standard formula:

Bullet Weight (Grains) X Velocity (Feet Per Second) ^2 X 0.000002218 (constant) = fpe

(fpe = Foot Pounds of Energy)
