TRY again whats going on here

[gunners]

I wrote this post an when I hit preveiw it took me to the log in page so I guess i'll do it again. Went to the range on Friday with my 22, 22-250 and my 7mm Rem mag,shot them in that sequence, starting at 100 meters. The 22 shot 11/4 -11/2 5 shots with CCI velocitors ,22-250 shot 0.7 5 shots and the 7mm shot 0.8 for 3.

Next up I moved the targets for the centerfires to 200 meters the 22-250 shoots 0.65 for 3 shots, I moved the scope up 3 clicks. The 7mm goes 11/4 @ 200 so getting very very happy

Then I moved the targets back to 300 meters movedthe scope on the 22-250 1 clickto the right 1st shot was a misfire fired 3 more then shot the 7mm unfortunatly I pulled the last shot. Now when I got to the targets I was gutted

Whats going on with the 22-250 1shot was so low it was off the paper the other 2 where 61/2 inches low and 3 inches apart I was expecting 4-5 inches low and 11/2 inch group .Was it the ammo or was it parallax error the AO was still set on 200 when I got home. The 7mm was a what could have been with the 1st 2 shots going under 1/2 inchand 5 inches low just like Winchester said and then pulling the last up beside the bull . So any ideas on the 22-250. Yes the scope is tight.

First, that is some damn good shooting.

my thoughts on the 22-250 is the 'clicks' on your scope are not the same as on the others...

Thanks blume, sorry it's taken so long for a reply. The scope is a bushnell 3200 7-21x40 so should be good. It usually moves correctly when sighting in an such. Think I might try another brand of ammo, and take along the remains of the Accutips for some comparisons. Know any that reach their stated velocity

I think you have a better handle on this than I ever would.... the furtherest I ever reach out is 100 yards and am happy if I shoot 6" groups at that distance. You are right, it probably is the ammo. I was just saying the 'clicks' on different scopes are not the same some are 1 moa and some are all the way down to 1/4 moa. Moa is close to 2" at 200 yards. It sounds like your 22/250 scope has a range setting in 100 of yards... the only way that 'might' work is if the scope is made specifically for 22/250 and then it would have to be for a specific ammo. I've only tried this on one scope for .223 and it didn't work worth a hoot.

5-6" or so low at 300 is within the nominal trajectory for factory .22-250 ammo zeroed roughly 1" high at 100 yards. Your first target looks like you are dead-on at 100, perhaps even slightly low. In addition, you have to consider that each rifle is a law unto itself -- some are faster thus "flatter-shooting", than others. Also, once you get out to that range shooter error and wind effect are magnified. So what you experienced may be nothing but a combination of you on that day, your rifle, and the ambient conditions (wind, temperature, light conditions, etc.).

One other observation -- when you fire at a given range then adjust your scope, you really have no idea what adjustment you have made until you fire again at the same range. Change to a different range immediately after changing your sight settings, and you are really just making a guess where those shots are going to go.

pisgah,the reason I adjusted the scope after 100 meters was as you noted were a little low I was trying to get it dead at 200. It did come out level if a little to the left. Which I based on the assumption that 1 click back to the right would be worth about 3/4 of an inch at 300 and what about the third shot it was about 71/2 low about in line with the ruler.
Just had a thought what about the fact the ranges are meters not yards that wouldn't help either. 327 yards I think would be the range.
I guess I can't believe after the groups at 100 & 200 why would 300 be so bad

Did you clean the barrel at any point? Dirty barrels can effect group sizes.

Gunners, this is the best feedback. I have helped others with the same situation and myself. I would clean my rifles and head back to the range. I would not make any adjustments at all and just shoot again with the same ammo with the same lot #s if possible. You really are right on track at 100 and 200. Even with the flat shooting 22-250 and 7mm when dead on at 200 you will be 7-8 inches low at 300. 300 yards is a long shot and many variables come in to play. Don't make evaluations on just one day of shooting - here are some things to check.
1.solid rest and consistent for each shot.
2. Is the scope level with the center bore of the rifle when mounted.This really comes into play when target shooting at longer distances-up to 200 scope adjustments may seem normal but at longer distances scope adjustments can be off if the scope is not perfectly level. Eyeballing it is not close enough for long range scope adjustments. I use the Wheeler level,level,level- you can get it from Midway. -you can read about it also .
3. Shoot more than one group. Sometimes if I am off just a bit I will keep it there for 2-3 range sessions to get a good idea of where I am at on different days and conditions -then when I have an average I will make a scope adjustment.
4. USE THE SAME AMMO -

Hope this helps -

Gunners, also 3"inch group at 300 yards is MOA and that really would be exceptional shooting and exceptional rifle. Anything, smaller than that would be a sub-moa shooting rifle which is usually not the norm for off the shelf rifle and factory ammo of any brand.
Don't get discouraged you really are shooting above average.

MOA - approximate 1" at 100,2"at 200, 3"at 300 etc.

My .220 does not close up until after 10 /12 shots. Then it is a dimer 5 shots @ 100 yds.( if I do it right). I do not clean again until it goes south. This is contrary to some, And what I had practiced until 3 years ago. OMO give it a go mate!

Ah yes that is probably why it went left at 200 after those 3 click adjustments up, the scope must be ever so slightly crooked. So when you adjust up because it's not going precisly verticle it moved the group left. The Wheeler levels was something I looked at 6 months ago but costs about 100 dollars over here. Have to try and get some off eBay.
1sparrow I shoot my groups as the rifle comes out of the bag,( put a patch to remove any oil, dirt or even insects) so includes the 1st shot (no fouling shots before I start). But like you I don't clean it after every group only when I feel it's starting to open up, which is one of the tips I've picked up off this forum. I believe this VSF is capable of 0.5 MOA consistently under the right conditons indeed it's best is 0.3 with Rem accutips
Side note: How about my Ruger hawkeye 7mm Rem mag isn't it coming along beautifully now with a few rounds under it.
