F.The best barrel twist rate depends on what type of bullet you are shooting. A fast twist rate such as a 1:7” twist barrel will work better with long-range modern bullets where as a shorter twist such as 1:10” or 1:11” twist barrel will work better with shorter bullets. Check the Quick Reference Sheets for our recommended minimum twist rates.The temp and elevation of the Berger Twist Rate Calculator are preset at 59 degrees and 0 ft. Under those conditions and at 2650 fps velocity, the 73 is predicted to have an Sg of 1.41, which is more than adequate. With the same velocity at 65 degrees and 500 ft elevation, the predicted Sg goes up to 1.46.The 7mm 190 Grain LRHT boasts a high BC, jump-tolerant hybrid ogive profile that is Doppler Radar verified with less than 1% BC variation.
