Hi, first time on the rimfire board. I did a search and got overwhelmed, so I'll ask a most likely exhausted question: What are you kids feeding your 10/22s? I've got a bedded 10/22T that's pretty accurate, but I'm getting wild fliers with this American eagle crap I just used up. Where now?
 
Rim Fire ammo

Federal classsic works well in all my 22's , I do however like CCI minimags because they have a little more juice.
 
CCI stingers
But really, go out and buy 10 different boxes of 50, and you will find out what your gun likes.
 
The accuracy of a .22 rimfire rifle may depend on the ammo you use.
I have a batch of federal gold bulk that won't shoot well in any .22 rimfire.
and I have found that the Federal champion target, Winchester T22, and I.V.I. target shoot well in most .22s.

Try a variety of brands of ammo in you .22 rimfire. Pick and shoot the brand that is most accurte.

BTW: I carefully pulled the bullets on the Federal gold bulk and weighed the cases ( I inspected the inside of the cases for powder before I weighed them), I then ran the cases through a Cooey single shot and fired them.then weighed the fired cases. There was no measurable weight diference between the fired cases, but the unfired cases varied slightly in weight. This indicated that the ammount of priming compound was slightly different in each case. I also weighed the bullets that were pulled, and there seemed to be no measurable difference in the weight of the bullets or powder charge.

As an experiment I weighed 100 unfired cartridges of this ammo and separated them out into three piles, one pile wieghed more than the average weight, one pile weighed less, and one pile (the smallest) was bang on to the average weight.
There were several that were very light that were set aside in a forth pile.

When fired out of a Savage .22 rimfire, each pile of ammo gave a smaller group (about half the size) than the average group, also each pile of ammo shot to a differnent point of aim. The ammo that was light shot slightly lower and gave a small group as well.
My conclusion. The amount of priming compound in a .22 rimfire cartridge may have more to do with apparent accuracy than other factors.
And my other conclusion from shooting several lots of the same brand of .22 rimfire ammo, some lots shoot better than others out of the same gun.
I suspect I got a really bad lot of Federal gold Bulk, maybe the lot where the machine spinning the priming had trouble metering the priming compound.
Too bad I didn't think to chronograph these rounds and see if there was a velocity difference between the sorted piles.

BTW, the Savage .22 I used is capable of ten shot grups of 3/8 inch (one jagged hole) with winchester T22. I shot several groups with T22 before and after I tested the Federal bulk just to make sure it was really the ammo and not me or the gun.

10X, Your conclusion was something that Eley discovered a while back - not trying to put you down, I am just confirming your statement. An article I read on Eley's manufacturing process (which outlines the hundreds of variables that Eley identified in production which affected accuracy) described priming as one of the most important factors in consistency in rimfire ammunition, hence why they implemented the EPS (Eley Priming System). After reading the article, I made a concious decision not to buy cheaper ammunition for target shooting (which I do mostly). I used to shoot Remchester ammo to "practice" but I have since realized that I can shoot better then the ammunition. I am not trying to say that I am an olympic shooter or the Winnington ammo isn't useful/good. But uncalled flyers and poor groups really can force a shooter to question his form/technique. The only way to be converted is to actually shoot match grade ammunition and "call" each shot after you pull the trigger. Doing this can show you a lot about your shooting.

Heck, I just wanted to know why this particular lot of Federal Bulk Pack didn't shoot well in any gun. I had an idea it was the priming or case thickness at the rim.
and thank you for the information you posted, I learn something new every day.
 
Any of these will do;

About 6 years ago I found a lot of American Eagle (cheepie) ammo that shot well so I bought about 3000 rnds and got good use out of them.

Federal Classic also shoots well for me in most of my .22s.

I use a lot of bulk Federal Champion for plinking. I sort it with a rim thickness gauge.
