sighting in?
« on: January 25, 2009, 02:27:28 PM »
Hello,
Just added a 3x9 leapers scope to my Gamo CF-20 and was wondering what most of you site your scopes in at, I sighted in at 25yrds.

Thanks!

I started at 20 yds and then went to 40 yds which seemed to fine tune it a bit more. Then I brought it back to 20 yds just to make sure that I wasn't over adjusting. But understand that I don't have a shooting bench yet. I shoot off a couple of wood pellet bags layed over a board on a trash can. It gives the support I need but I'm sure a bench would be a better still.

One other thing...make sure you use the same pellets throughout the process at least until your siteing is done. Different pellets will change your impact point slightly a longer distances due to weigth, aero etc. Once your zeroed in, experiment with other pellets to see how much your impact point changes. At least you'll have a baseline with one type of pellet. My scope is set with a wadcutter that I like.

I have most of my small game rifles zero'd at 25 yards, seem to work well for me.  Some of the more powerful ones I'll add some yardage, but for the most part 25 works well....

I sight in at 25 yards, using Beeman Kodiak, and RWS Supermag pellets in 177, Kodiak in 22.  For longer range I use the dots on the mill dot scope reticle.  I shot a "match" with springers at 50 yards, and 80 yards at 'spinner" and plate targets...off hand only!  I was shooting against other magnum springers...and custom 22 PCP air rifles.  My RWS 48 which I was shooting kept up with the best of them.  Shooting for fun.  All of my25 yards indoor shooting, and 10 meter indoor shooting is shot off-hand.  Wonderful  practice for big bore handgun shooting, and NSSA rifle musket shooting, 58 cal muskets off hand at clay birds at 100 yards...hit them too with my RWS 48!

27 yards.  Because that's how far the pine tree is from the picnic table. :-)
I was shooting at 30yds, but had to move to the other side of the house because my neighbor asked me to.
His dog was tearing up the screen door and his pet door, basically going crazy, every time I shot.
Now I can't sit in the house and shoot out the window.  But gotta keep the neighbor happy.  
My titan must be pretty loud considering the neighbor's house is about 200 yards away.

I was going to ask the same question.
I have the RWS 48 .22.
So, 25 to 30 yards would be the best zero range for this?

By the way, I am still alive and around. Just been busy.
Shooting when I can.

If you have Chairgun, you can enter the data for your particular rifle, scope, and pellet combo and it will tell you what the optimum zero would be for your rifle.  And if you don't have Chairgun, you should :-)!  It's a free download, check the Library, although I think it's well worth paying to register it.  If you need help with it, let me know, I've gotten pretty okay with it.  BTW, for springers I usually sight in at 20-25 yards, PCP's I use 30-45 yards.  Sometimes other ranges, depends on what I'm doing.  Later.

I start at 10 yds and then move back to 20.  From there it depends on the rifle and what distances I plan to be shooting.

I agree with daved for critters, every velocity and pellet combination has a sweet spot, and Chairgun is a heckuva good start on finding it. The beauty is finding the optimum zero for a given kill zone, so that your trajectory stays in the zone for the longest possible time. I do that with anything i plan to carry for critters in the field. Chairgun shows nicely how there are really two zero points with the kill zone strategy, the near and far points where the trajectory intersects the exact center of the zone. It is a cool way to account for range estimation errors, within reason.



This usually puts me somewhere between 27-33 yards for optimum zero, depending on the combination of pellet and gun. It really seemed to work on ground squirrels.



For fixed range target, I zero right at that range. I have the Diana 24 set dead on at 10m because that's mostly what I shoot with it. I back off to 20m now and then just to keep it honest and know what it will do, but it is not the most convenient range for me to shoot,at the moment.



Never shot FT but you would really have to know your gear.



I guess there would also be the "yard gun" tactic, zeroing to a known reference point like the pine tree. In tank gunnery (old school)we were taught to makea "range card", with landmarks of known ranges marked on the map, to facilitate rapid adjustment for anything that popped up on the battlefield.

I site in at 20 yards with my .177's and 30 yards with my .22. This seems to be a good base line to work from when shooting different distances and useing a bit of "kentucky windage",....but just a tiny bit mind you. tjk

I'm sure the neighbors didn't wonder at all when the range markers went up in the back yard here. LOL.  I used some of the vast number of trouser hangers tangled up in the basement...pull the cardboard tube free, fold the wires straight, slide the tube over them and straighten out the hook....poked into the ground vertically in ascending arcs at 20 thru 50 yards. Maybe I'll get fancy and tag a few with white yarn. Don't get any ideas about smearing peanut butter on them Jeff !
