Old Scopes and Rimfire Mounts

Howdy Folks!
This week we're back at the range to get the Henry H001 and Malcolm 6X Short Scope sighted in. To mount the scope without any machining, we've got the new "Rimfire Mounts". These are meant to mount the scope using the 11mm rail and the 3/8" dovetail found on many of these rimfire lever actions.

Big shoutout to @HenryUSA for making a rifle that's been used for years and still shoots straight!

00:00 Introduction
Out at the range today is the Henry H001, firing some .22 LR. Mounted atop it is the 18" 6X Malcolm scope, a straight-tube 3/4" scope with external adjustments. Mounting the scope is pretty straightforward with the Rimfire Mounts:
1. Attach the rear adaptor by tightening the clamp
2. Knock out the rear iron sight and install the dovetail adapter
3. Attach the scope to the mounts

These externally adjusting scopes have adjustment values that change as the distance between the front and rear mounts changes. For the setup here, I've got the mounts spaced 7 1/4" apart. This causes each of the 'big numbers' on the turret to equal 2.5 MOA. When shooting at 35 yards, each big number counts for ~0.8" of adjustment.
The turrets don't have clicks, so it's easy to stop at any point during the turret's rotation. Stopping halfway between two big numbers gives me 1.25 MOA, or ~0.4" at 35 yards.

1:01 Sighting In
Sighting in couldn't have been easier. The first group of shots were way high and to the left. They were maybe 6" high and 4" to the left, which came out to roughly 8 "big numbers" down and 5 "big numbers" to the right.
After the adjustment, the first group went right for the bullseye... or at least as close as the rifle would group. The second group revealed that the scope may need to be aimed up a bit more to group more closely around the bullseye.

04:07 Conclusion
That's all for today! After this video, I shot around 150 more rounds. There's no way I'd stop after just 9 shots from a .22.
