I am working on a load for my Tikka T3 in .30/06 with a stock barrel (1 in 11" twist, 22 7/16" barrel) and synthetic stock. I am using the following load data
COAL 3.25"
Winchester brass, full length sized
CCI 200 LR primer
h-4350 53.5 grains
Swift Scirocco 165grain bullet
I am looking for estimated velocity on this load, as I don't have a chronograph. I am using Swift's load data for the scirocco bullets as a start. I found a great node using a ladder test method at 300m in the 53.2, 53.5, 53.8 grains that put bullets into 0.53" at 300m. If someone would point me in the right direction of a ballistics program, that would be great. I realize the advantage of a chrono for load testing, and I will be borrowing one in a week to test some group loads at the above load ranges.
Thanks in advance
