Winchester superX 22 mag ammo loading problem

[Sir Henry]

I ran 32rds through my Henry, I had 4 that would not get an audible click with a locked chamber and 28 that did. I measured the rim thickness of the 4 that didn't and the reading as follows;

1.27mm
1.24mm
1.25mm
1.25mm

the 4 of 28 that locked with an audible click;

1.22mm
1.20mm
1.20mm
1.21mm

The complete boxes of Hornady and the Winchester Varmint all locked with an audible click.

Hornady;

1.15mm
1.18mm
1.16mm
1.17mm

Winchester

1.17mm
1.18mm
1.19mm
1.18mm

Your findings are similar to what I found.

So SH, can we say that the "rim thickness" is the reason for the ammo not completely chambering in a Henry.

I only have (1) 22 magnum firearm, do you have others?

Have you tried to chamber them and if so what have you discovered?

[Sir Henry]

The rim thickness was the reason for my Henrys not fully chambering the round. I also have several CZ's in .22WMR but never tried it in them.
