Consistency of springer muzzle velocities

[severnsider]

Used a Combro, but fixed it carefully with a little BluTak, and gripped the mout hard when test firning to minimise relative movement between the barrel and the Combro

Antoni - this has been done to death in other recent posts, but you might find that more meaningful readings are achieved if (a) you hold the Combro on with insulating tape and (b) hold the butt firmly (e.g. against a tree or very firmly into your shoulder) to ensure that recoil is controlled consistently. If you have the rifle held loosely, readings will be very variable. Works for me.
