hello,
if a rifle is shooting under moa at 100yds, can it be expected to shoot under moa at 200 or 300 yds?
thanks

big no,that is why I have always said don't bother with 100yds and use it just to sight in and determine point of impact before a hunt.

you could assume it would hold its accuracy, but a lot of lighter weight barrels dont. but 200 isnt that far so it might be under 2moa at 200

Maybe, if the shooter is up to it. I'm not, yet! Takes quite a bit of skill, because every bad technique you have a 100yds will really be magnified at 300.

No.


Some will, some will not. It's a head scratcher in some cases.

I've seen several rifles that would do sub moa at 100 but open a considerable amount at further ranges.

Good Luck

I have worked up loads that @ 100 yards would put a single hole in the paper, but, at 200 yards was lucky to stay on the paper...

Now, the only time I shoot 100 yards is for getting a new scope lined up and rimfire.

I work all my loads at 200 yards then move out further. when I shoot five shot cloverleafs @ 200, I know I have something to work with.

I suspect that shooting conditions like wind and the guy behind the gun have a lot more to do with the larger groups at 200 and over than the rifle in most cases.

I think you can "expect" the load to shoot the same moa but in actual practice, usually not. I've had rifles shoot better @ 200yds & some worse. I've never seen load shoot one hole @ 100 & then off the paper at 200. Most poor performance beyond 200yds is shooter error.

I'll agree, mostly because I am one of these people. My longest shot on game has been about 230 yards (but man was it a nice one )

MOA is MOA regardless of range or distance so in theory what you get @ 100 should be got at all ranges. Having stated that fact I have found with my 6.5x55 that it shoots tighter groups at (and beyond) 200 than it does @ 100 which seems to be quite common for the breed.

Not true. Only true if you are working w/ lazers or straight beams or the like. There are many factors that seperate a projectile from the straight-line theory such as spin, gravity, improper stabilization, bullet inconsistancies, and the list goes on...

A rifle that shoots 1/2" at 100 will not always shoot 1" at 200, 3" at 300 etc. even w/ the best shooter in the world behind the trigger, that's a fact .

I once had a Wby TRR 30-378 that wouldn't shoot under 1-1/2" @ 100 yds but had shot 3/4" groups at 300 yds. Explain that one.

just a thought?
Maybe your a better 300yrd shooter than a 100yrd shooter?

I've heard two stories that I don't actually agree or disagree with.

Some projectiles are supposed to be more accurate after 100 yards, as it takes them a while to "go to sleep". IE settle down.

Some long range .303 rifles were supposed to be more accurate at about 1000 yards as they "compensated" themselves. I've read how but since forgotten.

Occasionally you will have one that is an inch at 100, 1.5 at 200, etc. Supposedly this is caused by a bit of instability as it exits the muzzle. The best example I can think of to explain this is an arrow. If you shoot too light a shaft, you will see some not stick straight at 10 yards, but shoot well and straight in at 20, I believe this is caused by torque of the light shaft. One of the rifle builders i think Lazeronni, uses a different twist rate than common, and claims it is normal for his to be a bit average at 100, but groups open up not at all at 200. I have no experience with the Laz rifles personally though. I think it is a quicker twist that overstabilizes the bullet.

I think that may be true in some cases. A target gets a heck of a lot smaller at 300 yards than it was at 100, so we try to hold steadier on that little spot that moves more than it did closer in.
Just my $.02 (Plus tax!)

If possible I check my groups at 200m as that is the distance I shoot game at. The biggest problem at 200-300 yds is windage on an open range.If its gusty fine tuning loads goes right out the window.
The fine accuracy the bullet does need to settle down in flight This usually starts at 150 yds with 7mm or .30 cal.
An example is shooting your fine accuracy load at 50 yds and the groups tend to be bigger than at 100 yds due to the upsetting forces and tubulance as the bullet leaves the barrel. Think when you start a coin or spinning top going, it wobbles a around before the spinning settles down.
