New to this forum and have a question on Chronograph testing. Im shooting 160 gr.accubonds 59grs.IMR4350 cci magnm primers out of a model 70 winchester. With a 5 shot string and letting barrel cool down 10+ minutes in between shots I got.278.3 279.3 277.0 279.3 280.4. The Nosler 8th edition says my muzzle velocity should be 2943 +. Is this normal first time I had any of my rifles chronographed. Thx for any replys.
