sighting in Ruger 10/22 - questions
« on: February 11, 2011, 01:50:35 PM »
I have a Ruger 10/22 that I got about 20 years ago as a teen.  I didn't take the best care of it, and it has not been used much at all up until the last year, when I realized what a gem I had and decided to make use of it again.  The factory rear sight had busted, and the factory replacement just didn't seem solid to me.  So I had a gunsmith that was recommended to me put on some fiber optic sights and do a real thorough check up and cleaning of the gun.  He said it's in good shape and I'll never wear it out. 

Took the gun out this morning to sight it in, and was shooting decent groups (maybe 2 inch groups) off a rest at 25 yards.  I know that's not outstanding work, but didn't really notice much "bias" in the windage of my groups.  The were generally centered slightly below bullseye. When I moved back to 50 yards, noticed a definite tendancy of shots to be right of center - like 4 inches right, 75% of the time.  There was a bit of a cross breeze, - can a .22 bullet be affected by 10 mph winds that much at 50 yards?  I'm wondering if I need to adjust the windage of my sights.  I know the inconsistency is all me, and it's certainly possible that I'm jerking a bit during trigger pull, causing my 50 yd shots to flight right.  But I didn't seem to have this problem at 25 yards.  I'm shooting Federal bulk ammo (36 gains, copper-plated HPs, 5.6" drop at 100 yds).

Any thoughts/advice?

I dont think 10 mph wind will affect shot placement at 50 yards too much.  I would suspect that maybe 1/4 inch at most.

I would check your trigger draw and make sure you're not "dragging wood", which means you're pulling the rifle to the side a bit while squeezing the trigger.

Do you have access to a good gun vice to lock it down good and take some shots?

Thanks for answering my question about wind effects, Donald.  I figured that wind effects at 50 yds would be minimal.  I have a Lead Sled, but no vice - I'll use that to weight the gun down to make sure it's not 100% me before I make any sight adjustments.  This morning I was just shooting off a rest (no sled, no weights).  I'm sure you're right in that at least some of my problem is jerking during trigger pull.  Just surprised that it wasn't noticeable at 25 yds, but very obvious at 50.

In shooting, distance is a great revealer of all errors.  =)

Before my Appleseed class, I regularly dragged wood, to the point where I thought my scope was that far off. The rare times I didn't, I attributed to having a flyer in the ammo.

At least I sucked consistently.  =)

Here's a good write up on the Ruger 10/22 with ballistics tables, drift is considerable for a .22 at 10mph nearly an inch at 50yds. all vary with ammo type and especially round nose low velocity .22s any breeze will move them around

I'm off topic here,  but you are dead on.  Appleseed is a great way to learn and work on technique.

More on topic, having that 10/22 dialed in is great tool to practice, practice, practice.
