Question about Pentax Optics

1 Answer

Took my Pentax 4-12X 40mm rifle scope mounted on a Remmington 7mm mag bolt action rifle to hunt antelope in Namibia, SW Africa. First shot on a fine kudo blew up his heart and broke off-side leg bone. Excellent! Scope objective bell also bounced back and smacked my forehead well (my excuse is that I was draped over the backside of a large rock, only one foot reaching the ground, and it was the biggest kudu I'd ever seen from 150 yds.) , leaving me with a fair gash in the forehead. Then I used it on springbok, Hartman's zebra, and gemsbok. It seemed to shoot left of reticle centerline, but that could have been me--when I re-checked sight-in @ 100 yds(while in Africa @ 5200' elev.), it was perfect at 1.5 ins. directly above dead center. Okay, now I'm back in California and upon cleaning rifle before return to locker, noticed that the variable power adjuster ring is "stuck" at about maximum magnification--12X. It will not rotate clockwise to reduce magnification at all--with what I'd consider normal force applied. So what might be the cause(s), and is there anything I can do short of removal and shipping of scope for examination/ repairs?

You got it in one there,,,its all down to "head butting the scope"!
your head **** has pushed the eye bell up the scope body and has pinched or locked the power adjuster ring to the scope body
you have only two choices send the scope off for repair,,or buy a new scope,,,done even think about trying to fix it as you cant,,
it will need a strip down and then a re-gas (to stop it foging up)
so if you took it to bits the scope would be distroyed

Why is my ant 3x14 nightvision scope switching of by itself after every shot thats been fired. I have to switch it on after every shot thats been fired

The recoil is triggering the switch off. Either the on/off button is over sensitive or the battery gets momentarily disconnected. Check the battery terminals. It might also be part of the circuit rubbing on the scope casing and shorting it.

Does a Simmons model 533940 work on a 7mm Remington

Any scope will work on any gun. Its effectiveness requires your to match capability with need. A rimfire scope is intended for a 50 yard zero. If you expect to do most of your shooting at 50 yards, it will work fine.

Depends on how far you intend to shoot. Most zero their rifles at 100 yards, but if you intend to hunt plains game, you might want to use 200 or so.

The bolt release is not functioning on remmington 887

Make sure that you gun is well lubed. Some times after cleaning we can forget to properly lubricate the bolt and associated parts. Also a light lube might tend to freeze in cold weather making it harder to operate correctly. Use a heavier lube in cold weather as lighter lubes will freeze and make firing the rifle impossible.

Follow these steps

1) Mount your scope.

2) Use a bean bag or rifle mount and make sure that your rifle doesnt move much from its original position throughout this process.

3) Aim with the scope and shoot at a large backstop which will allow you to see where your shot lands, where ever that may be, it doesnt matter at this point. Again, make sure your rifle doesnt move much when firing.

4) With the rifle in the same position, look through the scope and adjust the crosshairs over to where your shot landed.

5) The scope now sighted in with the rifle. Minimal adjustment may still be required but at least your well within the ball park.

Happy Shooting
