Seeking some info on a Pentax Lightseeker II 3-9x model with "Perm-Align".
Features are as follows by Burris... but Pentax Perm-Align is likely the equivalent:
Posi-Lock is a coil-spring assisted retractable steel post that firmly and & securely locks accuracy into place.
Once the reticle is zeroed, the covering tube (red) replaces the internal spring (green) & locks the inner tube in place.
All scopes have one spring that allows the adjustment of the reticle. Some of the competition competitors offer a double spring whereas the double spring is the STANDARD for all Burris products.
As an optional, its possible to have the special Posi-Lock system.
Posi-Lock scopes remain perfectly zeroed year after year even during transportation.
My experiences so far with the Pentax Perm-Align:
A bit of background info -
I have been trying the scope out on a Tikka T3 Lite SS in .223 Remington with a 1 in 8 twist.
So far over the past few years the factory rounds with best accuracy results at 100 yards are the Hornady V-Max Moly 40gr as well as Moly 55 gr. and the Winchester Varmint Bulk Pack 45 gr. Contrary to more military thinking going with 1 in 8 twist on a sporting gun...Seems to like the lighter bullets driven right shy of 4000 fps even having the 1 in 8 twist... Just about perfect for what I use the rifle for. With these loads it delivers tack to dime sized groups routinely.
Lately, I had the options to play a bit with Black Hills 52 gr. Match "Blue Box" re-manufactured ammo using Lake City Brass using some sort of match hollow-points and some IMI 11B-M (Israeli made 55 gr match grade JHP/BT. Reasonably accurate stuff in my opinion --- Worthy or up to the task for this scope test.
100 yard scope test is on a calm, sunny day at the Rabbit Creek Range (not the easiest range to fire precision groups... nevertheless good benches, good conditions
Now onto the scope -
My #1 question to the shooters forum --- is the "Perm-Align" a good feature?
My experiences so far point to NO!
BUT... can anyone shed light on this dilemma I'm having???
Every time I center my groups up/down & left/right finding all is OK ----> until I turn in the "Perm-Align" locking feature...... after which the group shifts up & right or point of impact is off point of aim at very least. To me this is not acceptable, even if by only fractions of an inch. I hear all the science and understand the engineering idea, however I feel this "Perm-Align" feature is pushing the scope out of zero (after zeroing).
How have your Pentax scopes held up in the field?
Granted... this is a hunting scope having good glass (no match reticle) with kinda fat center cross hairs, yet how good is the tracking repeatability and re-zero based on its 1/4 clicks at 100 yards? I'm guessing this is not an option once the "Perm-Align" locker is engaged?
Are you generally pleased with your Pentax Scope and using this locking feature or do you leave it unlocked?
In the future would you purchase another brand?
