One year ago to the day I
posted about the Leatherwood PentaLux optics. Today I am writing about field
testing the glass I mounted on a wildcat Mauser
chambered in the hot 22-284 Winchester. After a routine scope mounting and bore
sighting in the shop it was off to the range for zeroing and some
evaluation. The day was cool, around 37 degrees along with no wind. I set
up the bench bags that would give the rifle a solid rest. Removing the
bolt to compare bore centered on the target with optic center of the reticle
proved right on target at 50 yards. 20 fresh rounds loaded up with 75 grain
A-Max bullets are charged with H1000 powder, a proven 1/4 moa load. You
see the rifle will be used to test the accuracy of the optics. Ocular
adjustment was easy with a few turns giving way to a crisp clear glass etched
reticle. Then on to dialing in the focus of the target which is made very
convenient via a side focus knob. Slipping a round on the benchrest follower
allows the bolt to lock up a snug chambering then a light touch to the 6oz Jard
trigger ignites the fun. Low and left is where the bullet printed. I adjusted
just a few clicks up and right and had the second shot dead center.
Clicks felt good and positive although seemingly quiet (I couldn’t hear a
freight train going thru a nitroglycerin plant ….thanks Clark). Two shots
fired and we are ready to go to the 100 yard target. After dialing in a
clear target at 100 yards the focus knob read 100! That’s factory
calibration for ya! So far things are going good at the bench. Another round
is chambered then fired out to the 100 yard mark. This time all that is needed
to center the shot was one click left of windage and with the .01 mill
adjustments pin point accuracy is easy. I was pleased with three zeroing shots
allowing the fourth shot to drill dead center at the 100 yard mark! Another feature of the PentaLux is an illuminated reticle.
I ordered green illumination and the rheostat has two off positions 180
degrees apart on the dial. This optic is built with a 30mm main tube,
fast eye focus, zero re-settable turrents (no zero stop) and side parallax
adjustment (a Leatherwood first). For a five times magnification (4-20 tested)
scope it has a compact profile at 14.5” long and the 50mm objective lets in
plenty of light. I hope Leatherwood/Hi-Lux will offer a sunshade for the
PentaLux line as I am fond of using them. Turrent covers protect the adjustments from accidental moving
when handling and moving thru the woods, while looking for that shot
opportunity at your game. A handy throw lever is screwed to the power ring for
quick positive dialing magnification. The reticle is calibrated
in mil’s and moa with ranging scales to size up targets at distance. Clicks are
in .01 mil’s (.036″@ 100 yards) as opposed to moa clicks (1″ @ 100 yards). You
have probably noticed the bright blue elevation turrent in the pictures.
This is a modification I made to allow quick zero settings at various
ranges. After turning down the knurled edge on the turrent, providing a smooth
round surface, I ordered a custom ballistic tape fromhttp://www.customturrentsystems.com (post
5/20/2015). The tape is calibrated for the 22-284 Winchester round with
meter marks from 100m to 1ooom. Ballistic load data is printed around the
top edge and click marks circle the bottom edge. The tape is created from
a vast choice of colors and fonts along with character sizing. The PentaLux is a well built scope with features that are easy
to use (side parallax, power throw knob, fast eye focus) and as always, the
erector tube stabilizer. I sent 20 rounds down range that day without a hint of
zero shift! I sent a 75 grain A-max bullet down range at 20 power only to
have the second shot enlarge the same hole slightly. After cranking the
power ring back and forth several times ending up back at 20 power.
In conclusion, I like the PentaLux in 4-20×50! Sure, it
could use a sunshade and I modified the elevation turrent for my ballistic
load, however, it is well built, holds zero and crystal clear with sharp focus.
Check one out on your favorite rifle. Just be forewarned……you’ll likely
buy other Leatherwood/Hi-Lux optics. |
