Nice old gun.

I wouldn't be happy with that result, ie the vertical stringing of the placement of the rounds, presumably due to the .222R barrel warming up after being fired, and expanding.

While the first round is on target, a .22 centrefire needs to have fine accuracy. Any additional shots are going to require a fair amount of adjustment for the aiming point.

I wonder if the expansion of the barrel is blocked at the bottom of the barrel meaning it can only expand up? Resulting in follow up shots stringing vertically? Maybe experts here could comment?
