I bought a used 40xbr, 20" heavy barrel, in .222. I took it to the range today, very disappointed! Beings I needed brass I bought a box of Nosler custom ammo in 50 grain. I shot a 5 shot group, dead on left/right, but strung out vertically 1.125" at 100yds. I had a 10 mph wind at my back. Any idea what to do to fix it? Thanks
40xbr .222 poor shooter ?

An easy way to check your scope is; shoot one shot at that target then adjust the scope to shoot 1" to the right. Shoot another shot than adjust the scope an 1" up, than a 1" left and then a 1"down. The last shot should be touching the first and you should have a square on the paper. If not check mounts or send scope back to manufacturer.

Go back to square one. Check torque for stock and Scope. If it was me I'd rip the scope off and install another scope and see if problem is still duplicated, as stated to many problems can come from the glass. The .222 in my realm is known for uncanny accuracy. I have a 700 BDL bull, handed down circa 1972. I'd also try the 52 or 53 HP match bullets. Over the counter ammo is not how I check max accuracy YMMV.
Hope you get to driving tacks

Try shooting in different weather conditions. If its heating up try shooting a group with a shot spacing of 2 minutes between shots. If it strings then look at the bedding. Definitely different ammo. Don't laugh but try some factory Remington ammo and see what it will do with some lighter bullets.
I agree

Borrowed an aluminum benchrest & shot 4-5shot groups at 100yds. Best I got outside to outside was 11/16" with factory Nosler ammo & 12x Tasco scope. Now for some handloads & a new scope.

Was it still stringing vertically or did you get some better grouping?

Omg....I didn't realize you had a tasco on a 40x. Not a match made in anyone's heaven. Trash that scope, get some quality rings, lap them for a quality scope. Then see what you have

I would never base a rifle's accuracy potential on the results of one factory load at one range session. As others here have stated, check all the obvious. Loose screws, damaged crown, worn throat. If good, toss another known scope on it and shoot it again, if results are the same, try another load in it. I have yet to find a .222 that wont shoot a half inch or less with the right load.

Find a good scope and some good rings personally I use buhler rings and 24x or 32x Leupold target scopes. You need to forget the factory loads and handload don't cut corners handloading measure and trim your brass, weigh each powder charge, check your chamber for throat depth and seat your bullets accordingly. Load in groups of 5 and change powder charge. when you have about 5 dif loads worked up go shoot and take your time so barrel temp is stable. If the bullet you use isn't working change bullet. But never change everyting in the load at once only change one component at a time till you find a good working load. Also forget the lead sled I use either two sand bags or an Atlas V8 bipod and a sand bag in the rear. You might have to switch bullets maybe a dif powder or even dif primers but that gun has the potential to shoot a 5 shot group with all bullet holes touching. Another hint pushing bullets faster doesn't equate to being more accurate. Keep us posted on your results and good shooting!

Like the rest of the posts said the action screws are really important. I recently acquired a R.E.M. 700 in 243 in a beautiful laminate stock. The feller was complaining of poor accuracy but I bought anyway. After some inspecting I see the new bolt stuck into the receiver if properly torqued. I just ground off about .030" and tightened it up now shoots reliably under 1" at 100yd.
