JOE BLOCKY 0 Posted June 15, 2008 Report Share Posted June 15, 2008 I recently got one those £40 Combro chronoscope, I fired my beretta co2 into it, and i am getting results like e.g. accupel pellets: 625fps, geco pellets - 719 fps. When i fired my brocock's in it, the velocities came up to what i expected ie. near book values. I did oil my beretta's barrel, so are these high velocities true because of dieseling or somthing else?? ps. the beretta has a standard velocity of 400fps or 550fps with co2 pel pellets Quote Link to post
SEAN3513 7 Posted June 15, 2008 Report Share Posted June 15, 2008 probably due to dieseling if you've recently oiled your barrel...............any loss of accuracy??? cheers sean Quote Link to post

Coney 3 Posted June 15, 2008 Report Share Posted June 15, 2008 Sounds like the results of dieseling but could be wrong. Quote Link to post

JOE BLOCKY 0 Posted June 15, 2008 Author Report Share Posted June 15, 2008 something is screwd but it aint the unit, as it gave correct muzzle velocity for the brocock me38! Quote Link to post
Deker 3,478 Posted June 15, 2008 Report Share Posted June 15, 2008 (edited) something is screwd but it aint the unit, as it gave correct muzzle velocity for the brocock me38! What is me38??? And, if apparently it was correct with the Brocockl, how did you get 715 ft sec with other stuff..did you oil the barrel in between? Edited June 15, 2008 by Deker Quote Link to post
