100 yard ammo test

Lol. It kind of reads like an ad for CCI doesn’t it!
It’s just a free iPhone app “SubMOA”. Occasionally glitches a bit and and is a little finicky, but I’m cheap, so...
And again, I’m no competitive shooter, so I’ve got no right to comment, but if you shoot 1-4 inch targets, and you’re trying to see how many rounds you can put on a 1-4 inch target, wouldn’t you be better off using standard target sized “circles” and see which ammo can put the most of 25 rounds in each circle? Thus, it becomes less about circle size (1 7/8” vs 2 2/4”) and more about percentage of rounds on target. You may well find that one ammo is better for 1” targets, and another is better for 3”, etc. The difference being, which brands have “flyers”, and which brands have “FLYERS!!” ;-)
Spent a few hours on range today. Tested 6 different lot.
Interesting to see that the cheapest ammo (SK Magazine) did just as good as the SK Match. Best today was SK std and Eley Force. Starting to think that SK ammo and others don't like the cold.

I don't understand why all rounds were not included in the group size circles sown.
You cant ignore "flyers", in fact there is no such thing as "flyers".

Ideally, I want my rifle/ammo combo to group no more then 1/2 the size of the target I am engaging. This gives me some wiggle room if I miss the wind call or just don't get a solid shot off due to awkward position.
So for 4" targets, I want 2" groups or smaller UNDER THE CONDITIONS I WILL COMPETE IN. With your testing, if you competed the same day, you would be giving up a lot with the ammo choices you have.
I have no problem if my miss is due to driver error but it gets real frustrating when I have no idea where my next shot is going to land due to error in my gear.
Consider testing more expensive ammo like Lapua and high grades of Eley. My rifles prefer Lapua CenterX or the equivalent Biathlon option. This lets me shoot 1 1/4" or better at 100yds which is plenty tight for the targets I am likely to engage in competition. Not my best group... but my worst/Average groups.
Unfortunately, we don't get to pick and choose the shots we take in competition so we need to count where every shot goes. If you are getting alot of flyers which go outside your target, you need to upgrade your ammo.... or barrel or barreled action.
Now costs will ramp up quickly so I suggest you find an affordable option for practise and an expensive option for competition. Just make sure the practise ammo will still let you get to 100% affective hits if you do your part. That might mean shortening up the distance. You never want to practise with a system that is inconsistent as that hurts your confidence.
Gives you the best of both worlds.

Yep... this is the right way to think about your ammo and testing. Pick the ammo/rifle combo that allows for 100% of the shots well within the boundaries of the target you need to hit at distance.
Then the rest is up to the driver to put that 'group' on the target.

I was at the range yesterday with my RPR 22, -1c, federal bulk target looked like buckshot at 50m. CCI SV on the other hand had really nice groups.
As I stated in another post, OE mags were sloppy and damaging the bullet when cycling a new round. I bought a Butler Creek 10 rd mag for the 10/22
and every round cycled flawlessly. I had a a few FTE but that's nothing for a cleaning to cure.

Just noticed ur groups at 100 yards and in my opinion this is where the difference in quality ammo really starts to show its expensive ugly head! Despite what some people may think no rimfire ammo will produce as good results as the same ammo in warmer weather. There is a reason that the best ammo companies in the world make rimfire ammo for cold weather applications usually Nordic or biathlon. All rimfire ammo will not hold a candle to that specifically designed for the cold once the temp drops below 50 degrees. The lube is not the same as are the primers or the powders used. Not saying you wont find an ammo that wont shoot good but there will be a biathlon that will outshoot it by a considerable margin day in day out.
