Weight: Published weight in grains
Name: make and model
Length: measured in inches, may vary from published data, especially for plastic tipped LFPs.
G1 BC: G1 Ballistic coefficient from published data.
Cost: Published cost, mainly from Midwest USA web site.
Muzzle Velocity: Most values are estimates or extrapolated. To be updated.
Minimum Velocity: lowest velocities required for beginning of expansion in PermaGel.
Maximum Range: Range at which the LFP would drop to Minimum Velocity based on the estimated Muzzle Velocity.
The minimum velocities were determined using synthetic ballistic gelatin (PermaGel) at a distance of 10 ft. Loads were reduced to give velocities from 1600 to 2400 fps. Velocity was measured at the muzzle using a Magnetospeed chronograph.
The maximum ranges were calculated using the JBM Ballistics Trajectoryhttp://www.65grendel.com/forum/showt...389#post146389
I hope you find this thread useful. My personal thanks to BluntForceTrauma for enabling me to set up this locked sticky thread. And a special thanks to SneakyOne for providing cut down versions of many of these LFPs so that they could be captured in gels at low velocities.
Be safe,
