I was wondering if anyone had an estimate on the velocities that I am getting out of these loads. I dont have access to a chrony. They are all very accurate out of my rifle. Below are the specifics.
Rem 722 .257 Roberts
OAL 2.833
Win LR primer

1)Sierra 87gr Spitzer
42gr IMR4350

2)Sierra 87gr Spitzer
46gr IMR 4350

3)Sierra 100gr Spitzer
43gr IMR 4350

4)Sierra 117gr SPBT
43gr IMR 4350

Thanks for the help

Velocities calculated with internal ballistic calculator with barrel length of 22 inches. Your mileage may and probably will vary, depends a lot on fast barrel or slow barrel. Have seen that software be spot on or off by 100 or more fps. The best way to know for sure is a chronograph.
