Summary

[edit]
Description

Author: Metroplex, Source: Misc data.
Note that the ballistic coefficients used for SS196SR and SS197SR come from Hornady for their 40 grain .224" diameter V-Max bullets (0.2) The ballistic coefficient used for SS195LF was guesstimated from the Berger .224" diameter 30 grain Hollow Point (0.193), since the actual SS195LF bullet is a 28.3 grain .222" diameter aluminum core hollow point. The velocity used were derived from PS90 figures (16.x" barrel) and the scope height is approximately 3.75" (from center of MC-10-80 optic to center of bore).

A 50 yd zero was used since almost every outdoor rifle range will have access to a 50yd range and it also allows for a rather flat trajectory out to 150m-200m, near the max range of the 5.7x28 cartridge and the P90/PS90 weapon systems.
