sighting in new scope
 

hey everybody, i just bought a Sightron 3-12x 42mm scope for my .270 remington 700ADL, i had it boresighted last night after buying it. i took it out today to sight it in. i started at 25 yards, my first shot was about 6 inches to the right, i adjusted and got it hitting dead on at 25 yards. my next shot was at a distance of a little over 100 yards, i hit about a foot to the right. am i doing anything wrong? what should i do now? this is my first real scope, i used this rifle with iron sights for a year but i have 150 acres of farm land and have gotten into varmint hunting so i wanted some accuracy. what should i do now?

Double check all mounting screws for the bases, and the scope rings. Be sure they're tight, but don't overdue it - you don't want to strip one. As to the boresighting - by who?
Mr. McGoo:D
Anyway, if all is tight, and seems ok, I'd head back out and re-check zero at 25yds.
If ok at 25yd., then try a shot or two at 50yds. Zero it at 50yds., then proceed to
sight in at 100yds.
If the windage is way off, you might try (if possible - depends on bases/mounting hardware) adjusting for it some by moving the rear ring in it's base. I'd be sure to zero at 50yds before going on out to 100.

i love this thing

Import,
First,bore sighting is going to put it on paper,but now you have to fine
tune the scope.The first thing I do after installing the rings, is check
them to be perfectly aligned with a ring aligner from Brownells.
If not they will tweak the scope and give you a fit when trying to
zero in the rifle. They are not a perfect machined pair.You might have to hone one of the rings.
Also, tighten all screws evenly and on a cross pattern.

Second, I always buy aleast 4 boxes of different brands of ammo and weights
to see which one the rifle likes best from a bench rest, starting from 25,
50 and 100yds.

i'm shooting remmington 150 grain core lokt rounds now... should i switch? i will be using the rifle for varmints at ranges up to 300 yards and also for deer... should i use 150's or 130's?

RE: sighting in new scope
 

In Fla. not every body,but the deer hunters I know shoot 130grNP.
On yotes and similar varmits I would shoot 115gr core-lokt-psp.

RE: sighting in new scope
 

so the 150's arnt any good? are they less accurate?

RE: sighting in new scope
 

Can be more accurate. You might have to try 130, 140 and 150. I like 140's.

RE: sighting in new scope
 

150gr. bullets in the 270Win. are intended for BIG game hunting, and should not be used
for varmints.
Remington makes a 100gr. bullet loading for the 270Win., and this would make a fair
varmint round. I've tried 'em in my 270, and I get very good accuracy with them.

Another option, go with 130gr. bullets. They will make a good deer hunting load, and
can pass/be useable for some varminting. 130gr. for the 270Win. is available from all the ammunition manufacturers so if one brand/style doesn't shoot too well in your
particular rifle, try another (Remington, Federal, Winchester, Hornady, etc.)

RE: sighting in new scope
 

Unless you are going to do a lot of varmit shooting, I would just shoot the 130 for everything. Any brand that shoots good in your gun should handle deer or varmits. The Corlokts will do fine.

I THINK YOU MEAN IMPORTSLAYER.

RE: sighting in new scope
 

didn't see anyone mention it but the first thing you want to do BEFORE you bore sight is run both the windage and elevation screws all the way in and all the way out. count the turns and run back in 1/2 way on the windage and 1/3 on the elevation. This will put your crosshairs in the middle of their range (windage) and give you plenty of adjustment for elevation. If the windage screw is all the way in or out, when you adjust elevation you can pull the crosshair right or left. Now boresight and use your coarse adjustment on the rings to get close. I've had good luck just using a lazer pointer ($29 at office max) pushed right into the bore. Use a piece of electrical tape to hold it "on".

Also, you need to be sure the crosshairs are straight and plumb with the center of the rifle.

Good luck

I've never used a bore sighter and don't bother with shooting at 25 yards or even 50. I go right to 100. My method involves taking the bolt out and sighting down the bore to the target while the rifle is held in a steady rest. I try to center the target in the bore and compare that to where the reticle is situated on the target. I make adjustments to the reticle as needed. This takes just a little while going back and forth looking at the target through the scope and through the bore. When satisfied that I'm close, I shoot a group of 3 shots. This usually puts me within 3 or 4 inches of the target and from there I can make final adjustments to the reticle.

RE: sighting in new scope
 

SM I agree that their's not much to be learned by shooting at 25 yds with fast cartridges. The point I'm making is that your crosshairs need to be as close to middle of their operating range as possible. With the gun in the vise and a red dot on the target it's easier to tweak your coarse adjustments. Save the reticle screws for fine tuning.

RE: sighting in new scope
 

first thing i would do is get rid of the remington shells. never had any luck with those shells. federal , pmc , winchester seem to always be better shells. don't allways blame the scope or gun. many times it is just the shells. you have to find the ones that your gun likes.

RE: sighting in new scope
 

Why? Sure some guns may not like a particular Remington loading, but then again .....
My Sako (308Win.) shoots a ragged hole at 50yds., and does about 1" to 1-1/4" at 100yds. with Remington 150gr. Core-Lokts.
My Rem.700LSS Mtn. rifle (270Win.) likes 150gr. Rem. Core-Lokts, and the 100gr. PSP's.
What's even better - they both shoot to the same POI at 100yds. Groups run 1-1/2" to
a little over 1", respectively.
My Ruger 77/22 (22mag.) loves Remington V-Max Premiers - one ragged hole for 9shots.
Am I just lucky? I don't think so. Remington makes some good stuff.

RE: sighting in new scope
 

i shoot somewhere in the area of 15,000 rounds a year threw many differant guns. and the only shells that i have sent back the factory for testing were remington. shotgun shells that would not eject, to missfires on center fires and dented brass on rimfires. i don't buy shells by the box we buy them by the case.
am i just unlucky? i don't think so. remington has some quality control issues.

RE: sighting in new scope
 

i took the rifle to the range today, shooting 150 grain core-lokts, i have it shooting 1 inch groups at 100 yards and every time its off even a little i notice its because of error on my part

RE: sighting in new scope
 

but i would consider shooting winchester or hornaday 130s... whats wrong with using 150's for varmints?

RE: sighting in new scope
 

besides the fact that its major over-kill lol

RE: sighting in new scope
 

i had the gun sighted in perfect at 100 yards yesterday, went back to the range today and i was shooting horribly... it was deffinately my fault though, i couldnt keep the gun steady, i felt like i was flinching, idk what my problem was, i really couldnt concentrate. i think my arm is beat up from all the shooting and weight lifting i've been doing lately... shootings great, but how am i gonna get all the ladies without my real guns? haha, anybody else have bad shooting days? i know it happens to me shooting my bow every once in awhile

RE: sighting in new scope
 

everybody has bad shooting days. anyone that tells you he can shoot good everyday is full of it. and if you watch his nose real close you will see it start growing.:)
