In this picture, the 3 holes touching were with my suppressor on and the other 3 were with it off. The only break in I did was to sight in my rifle. This is how it has shot since the first 3 rounds I put through it. Attachments:

And this is how crooked my scope is, but the cross hairs look level when I shoulder my rifle. I shoot this rifle out to 400 yards with no problems (its only a .223) It shoots minute-of-coyote just fine! Attachments:

72camaro,
You'll almost always get a flyer or two right after cleaning, I've never had one that far out but every gun shoots differently. If your going to shoot for groups after cleaning always shoot a couple of "foulers" first, before you get serious about your groups. I think after you shoot it awhile it will tighten up and your first shots won't be so far out. The barrel can be a little warm but when it starts getting to hot to hold your hand on, it's to hot. I don't even like to let my broken in barrels get that hot. Don't give up, I think your groups will get better as your barrel smoths out. Have fun.
Bob

I cant see why you would ever need better than that! Nice shooting and NICE RIFLE! Love the camo pattern on that by the way.
This is the perfect thread for a buddy of mine who is in the market for a varmint rifle/scope.
Thanks Camaro
ERic.

I shoot this rifle out to 400 yards with no problems (its only a .223) It shoots minute-of-coyote just fine! I'm still struggling thinking with the scope that off kilter it still shoots where you want it on long distance. Do you shoot into the same amount of wind from the same direction every time? ;D |

Everybody shoots their gun different and looks through the scope different. That's why you need to do your own sighting in and load developement. What works for one person probably won't work for the next. It's just about impossible to shoot in the same wind conditions everytime.

72camero,
You are shooting a 58 grain bullet out of that gun. That might be a little light for a barrel that is meant to shoot a heavier bullet, I think that is why it is shooting so erratic.
If I were you I would try an 80 or 85 grain HP bullet, or the 87 grain Vmax. Every 243 Win, that has come straight from the box, shoots the heavier bullets very well, the 100 grain bullets will group very well from that gun.
My hunting partner shoots a Factory 243 Win, with the 87 Vmax, it shoots 3/8" at 100 yards.
Shooting test groups at 200 yards is not a good thing. Shoot groups at 100 yards, and if you want to shoot at 200 yards for practice, and to see where your rifle shoots, that is good.
With the 243 Win, sight in 1 inch high at 100, that should put you right on at 330 yards.
Try the heavier bullets, at 100 yards, I think that will make a big difference in your groups. It seems that your gun will not stablize the lighter bullets well enough to get good groups.
It is not about the weight of the bullet, although, they use the weight to indicate the profile of the bullet, compared to the barrel twist. It is about the length of the flat body of the bullet, that indicates how the bullet will react to the twist of the barrel. The heavier the bullet, the longer the flat of the body, short bullets in a in a 1in14 twist will shot good groups, where it will not shoot a group in a 1in9 barrel. A 1in9 barrel will need a longer profile bullets to shot correctly, because it is a faster twist.
What 1in9 means is: there is 1 complete rotation in 9 inches of barrel. where a 1in14 means: one complete twist in 14 inches of barrel, which is slower twist.
I hope that is clearer than mud, and make more sence!
Gary

I'm with you on the barrel twist and the ammo. If you divide the .845/2 for grouping at 100yds, that puts 4 of them at .423 center to center, I'm still happy with it. The two on the bottom right are throw away shots to see where I needed to adjust the scope, the only one that should have been on and wasn't was the top left shot and at 100yds that would have been about .75" off where I wanted it to shoot .6" above center at 100yds if also divided by 2 from 200yds which was 1.5" from the .6" above center, wanted point of impact.
From the reading I've done with the .243 it appeared that the 58 grain VMax did little pelt damage and I did not read up on the Hornady 87 VMax, but yes, it would probably be even more accurate but I've got quite a few 58's to go through before I switch to 87's. I was reading up on the 58's and several people with the same barrel twist said they did fine so off I went, right or wrong.
I do appreciate everyone's help on this and do realize with '0' coyotes under my belt that I've got some learning to do.

Yeah, Gary is right on the twist. But you're gun seems to be shooting them pretty well. So, go with it. When you use them up give the heavier ones a try. You might also try Barnes bullets, they are longer for caliber because they are all copper. I've never used them but a lot of guys report good results with them. Go get some coyotes, good luck.

Read more: idahovarminthunters.proboards.com/index.cgi?board=rifles&action=display&thread=771&page=2#ixzz2F7xsBatbJust asking, why would it be wrong to sight in at 200yds, in this case shooting towards center lands the grouping .6" above center as it is suppose to, and I have a confirmation shot at 100yds that was .6" above center where it was suppose to be for the arch points I'm looking at to zero at 225yds? Wouldn't anything at 100yds be half of what it would be at 200yds? Wouldn't it be best to sight in at where you want zero to be, like my gun would be 225yds, if the range went to that instead of it stopping at 200yds?

We took out my buddy's brand new Savage Axis .223 today to sight it in and break in the barrel. Keep in mind we were dealing with a good 10 - 18 mph 180 degree wind all day long. The first 10 rounds were shot at 50 yds to get it hitting paper although the first shot was about 3" to the left of the bulls eye. We did the shoot/clean/shoot/clean method for the first 10 rounds and then went to shooting 5 shot groups. We moved out to 100 yds for the 5 shot groups. Scott put 2 rounds into the same hole and then followed it up with two more shots for a measured 4 shot group of .465" . Thats awesome for a brand new rifle and factory ammo! Like all of us here Scott is addicted to the sport  |
