This is a field evaluation of the new Leupold Mark 4 HD 2.5-10x42mm TMR scope.
This scope was purchased from a dealer by @Ryan Avery from money donated by a forum member for this scope to be evaled. The ammunition used was Federal Gold Medal Match 168 SMK that was purchased by Shoot2Hunt for these evals. The 20 round proof group was right at 1 MOA.
The scope and weight-
21oz-
Turrets:
Elevation is multi rotation, zero stop, push button lock at zero. Windage is capped and rotation limited.
Push button lock is shown-
Reticle: FFP TMR
This is a generally standard .5 mil per tick reticle. It has in open center.
2.5x
10x
Zeroing:
Mounting as normal (and per manufacturer instructions)- 18 in-lbs on ring caps, 65 in-lbs on base.
Boresight, than 1 round. Used the reticle to measure offset. Made the adjustments and then went to left dot and fired the remaining 9 rounds. Made a Up .1, and Right .1 mil adjustment, and shot once at the center dot to confirm.
Drop Evaluation and “Tracking”
For an explanation see- Scope Field Eval Explanation and Standards
The “test” consists of three 18” drops on a mat- one left/right/top with a shot to check zero after each drop. Then the exact same thing repeated from 36”. Then three drops on all three sides for nine drops on the last part- 15 drops total. This is not “abuse”. The 18” drops are a joke really. The 36” start showing something. And when a scope make/model consistently goes through the whole thing without losing zero, failures in actual use are almost unheard of.
This one was conducted on semi loose dirt, with a 2x 1/2” padded mats on top.
Everything went fine until the first 36” too drop. Shots as marked.
Took the rings and scope apart, remounted using 22in-lbs in ring caps, and checked zero.
Bottom row of dots. First two shots were high left, adjusted, next are on the bottom left dot, adjusted D.1 and R.1 mil, and fired one shot on bottom right dot.
Drop Eval #2. Better, but not correct.
