Remmy 700 SPS Tac 20" BB Velocities

[winxp_man]

I did search for 20 inch BB velocities and i cant seem to find good info...... anyone one that has cronoed there remmy 700 20 inch barrel and can share there info i appreciate it.... type of bullet,type of powder and amount. thanks again for info...

[ar15barrels]

They are about the same as 20" AR-15 velocities.

Using Quickload, I can tell you that 25gr of 748 under a 69gr SMK would get you the following velocities:

16 2811
18 2891
20 2960
22 3020
24 3072
26 3119
28 3161
