The firearm thread

[jrandom]

Just after some advice please. I have a Ruger 10/22 fitted with a Bushnell 9x40 that needs zeroing. I've always been a shotgun man so the little semi auto is something new to me, as is zeroing. Can anyone help me out with an easy fix or point me in the right direction of someone who can help?

Measure out 25 yards. Put a piece of paper up on a board at that distance with a mark in the middle.

Put your crosshairs on the mark and pull the trigger. Shoot 3-round groups. Use a rest for the rifle so that you're not relying so much on your ability to hold it steady. Observe where the holes are grouped around.

The click-adjustments on your scope should be quarter-minute of angle. That means that four clicks move your point of aim one quarter inch to the left at 25 yards. Click your scope's clickers up, down and round about as required until your 3-round groups are centered on the mark in the middle of the paper.

Et voila, your scope is zeroed.

Enjoy!

Another way is to again have the rifle supported on sandbags.

Get one of thos cheap laser the go on key chains and put it in the breech.

The light should show a dot on the target.

Centre the crosshairs on the dot.

Take out the laser.

Test fire and fine tune

OK. I'd read all sorts of stuff about pre-zeroing and bore sighting first of all. I suppose I could use a Black and Decker work bench thingy to hold the rifle steady?

Sounds like it will work just dont fire the rifle whilst in the workbench thingy

Bore sighting is what Mr Merde's talking about.

Personally, I don't have a laser pointer, so I find it easier to take a plink at 25 yards, and if the scope's so far out that the shot's off the paper, move in closer until the shot's on target and adjust from there.

(For a .22LR, bullets hitting bang on point of aim at 25 yards is what you want.)

Entirely up to you which way you do it.

Aaah, so that's not good then?

[Mr Merde]

Could scratch your woodwork on the rifle if it recoils and everything does recoil.

As a shotgunner you should know that.

Newton's third law. I presumed you meant that it was not ideal to gain the grouping.

It's the 10/22 all weather carbine so it's mainly plastic and spends time strapped to the quad anyway.

You shouldn't need to clamp it down, you'll have to adjust it between shots anyway, just rest the forestock on something softish and hold your aim point by hand and eye, at 25 yards that should be a doddle.

OK, I'm gonna give that go. Need to make more head shots on the rabbits so the meat isn't wasted!

Anyone here use a dog or dogs for retrieving?

Re your scope: a 9 X 40 is waaay too much scope to be practical on a .22 - a 4 X 40 is any amount, a 6 X 40 would be the limit.

Oh, and about 23mm high at 50metres will have you back on target again at 70meters. (IF my memory serves me well).


Get the book "The 22 Rifle" - well worth a read.

Tell that to a certain KBer who's just put a 24X on his .17HMR!

I agree with you on a 4X scope being ideal for shooting at small, moving targets within 100m. And I'm not a fan of cheap adjustable scopes; the optics are invariably shit. The plain Tasco 4X models do the job quite well, though.

Err, yeah. Targets seem to move around a lot more in a big scope! But that's what is fitted so that's what I'll stick with. Gonna have a go at zeroing in tonight.

I bet a 24X is just dandy for an evenings stroll pinging bunnies!!

17 will have a waay longer range than most .22s - and the parralax error of a scope designed for use at longer ranges will cause problems when most of your shooting is at 20 to 65 metres.
