velocity problem

hey men, im shooting a 6br and my load is
lapua brass
cci br4
33 gr's of vv n135
65 gr vmax .010 jam in a 14 twist hart.

i got the load info from this site and it claims it will shoot 3350 fps and im getting around 3670 fps. is this correct or could my chrony be wrong. Thanks, SPM
 
Although I haven't used VV135 in a 6BR, your velocity sounds realistic. In my rifle with 3 different 65gr bullets and either AA2230 or Reloder 15, accuracy has been from as low as 3370 to as high as 3710 depending on the combination. The loads I'd be using with AA2230 clock 3675 and 3684. Barrel is a 24" Hart 14twist, .271" nk, no freebore, bullets with Lee Lube, about .005" off the lands .
