22lr half inch at 100y

I do a bit of long range rimfire using RWS R100. Have gone up to 600 yards. Once you go past 50 metres/yards, it is very ammo dependent.

I find .5 MoA at 100 yards very difficult to believe. I believe you can get 0.5 on the occasional group, but I don’t believe you can get it consistently. People post their best group, which they got once when the stars aligned, then they claim they can do it “all day long”.

I could show you a <0.5 MoA 100x group with a standard Tikka T1x, but it can’t do it consistently or even often.

Refer Snipers Hide 6x5

Six x five shot groups.


There are hardly any entries with an an average 100 yard group size of <0.5 MoA. And these results are the average of the groups on the shooters best card which they have submitted for scoring. Not the shooters overall average.

I recommend buying a box of several types of premium match ammo and see what your current rifle can do. Make R100 one of the ones you try. You must test the ammo at 100 metres/yards or more. Ammo which gives you tight groups at short range can fall apart at longer range due to inconsistent muzzle velocity, bullet shape, ballistic coefficient etc.

It will also be very wind dependent. Even a head or tail wind will affect your elevation. A 10 mph crosswind will move your impact 4 inches.

You totally summed it up when you said "Once you go past 50 metres/yards it is very ammo dependent".

RWS R100 is one of the rounds that I was thinking of when I mentioned using the right ammo in my 452 varmint. I've also found R50 to be very good too, also Eley Match (not quite so good). I've not tried Tennex.
All shot on paper targets, I limit my subsonic sporting use to around a maximum of 50 metres.
 
The accuracy of any 22 is limited by the ammunition you use - and 22 ammo varies wildly
Unless you put the very best stuff through it, you ain't getting 0.5moa, and even then, not all the time

Maybe not half MOA however my tikka T1 will shoot a consistent 1 MOA and it’s nothing special…I agree the ammo is a big factor though.
 
Ten rounds CCI at 50 sitting off the knees in the garden with the Brno as example
Nothing wrong with that at all. Good group, all in one hole.

Scaling of the 10 ring (ISSF target, 10 ring is 10.4mm diameter), you have about a 10mm group. Definitely sub-MoA.

That translates to a 20mm group at 100 though and that's before you factor in MV and BC variation in your ammo, which doesn't really matter at 50 but does at 100. eg I've tested out CCI standard and minimag at 50 and it all goes in one hole at 50, but at 100 it opens up to a 2 inch group. Have done the same test with Tenex and several other match ammo and they all go in one hole at 50 but open up at 100 to varying degrees. In my case with RWS R100 opening up the least and giving repeatable 1 MoA groups at 100 on a good day out of a factory rifle.

I don't think anyone is disputing you can get sub-MoA at 50. Getting sub-MoA at 100 is hard and very, very difficult to do consistently.

There is also RWS Long Range.

Now product, have not tried it yet but am looking forward to doing so. Looks like it has slightly higher velocity than R100 and a slightly different shaped bullet with a higher BC.

I haven't seen the RWS long range, thanks for making me aware of it.
I did try some RWS high velocity at one time and that was probably the most accurate .22 ammo that I have ever shot out of my 452. Unfortunately I was only able to shoot it at a maximum of 50 yards.
 
For consistent accuracy at 100M with a .22 you need 3 things you can control, a half way decent rifle, decent ammunition and a decent shooter.
Miss out on any element and consistency goes out the door.
You can’t control the wind, and if everything else is consistent that’s why your groups have opened up.
As already mentioned, ammo which does well at 50M may fail at longer distances.
