10/22
I shot 10 round groups (at 20 yards) off sandbags once after buying about 10 different brands of ammo.
The tightest (and nearly flattest) ammo was Remington Yellow Jackets ($9.99 for 500 rounds).
It was the dirtiest ammo and the bullets seemed loose in the case.
Each gun will have its own preferences having nothing to do with price.
I most certainly don't want to start a "ammo war" here. And I NEVER collected data from 25 yds. yet. But I have most certainly found a
HUGE difference in expensive ammo VS cheap ammo. I have all the
cheap ammo from Winchester, Remington and many other cheaper brands. And yes... many are "dirty". I'm
NOT making light of those brands prices as for most/many they
ARE expensive. But the more expensive bricks / ammo are for a reason. If anyone would like a list a of the "better" ammo I've used/tried I'll post... but DOES that mean
THEY ARE THE BEST for your rifle.... NO! All of my opinions come from 50 yd. bench shooting experience only for now.
As you stated above:
"Each gun will have its own preferences having nothing to do with price." That statement may be true. But I promise there is a difference between $10.00 bricks and $100.00 + bricks. And the price climbs easily from the $100.00 bricks.There is a HUGE difference in ammo according to prices. But in order to "prove" it you have to invest into the ammo and that costs up to 2-3K plus for all to try.
YES... each rifle does have its preferences... and I totally agree.
But it starts with a high quality machined .22 rimfire and then handed off to world class ammo. And from there breathing, aim and a world class trigger pull (I skipped some also).
I admit I am just getting into the .22 rimfire competition. And.. I have not entered into any competition yet and won't until I'm ready with my rifle. But this new adventure came from a professional archery background and a desire to excel and achieve now at age 63. I and my Grandson (15) this summer shot my new KIDD .22 target rifle. We shot many different high end brands through it and kept data. My Grandson and I both know a "good shot" from a bad shot. He was taught early on. And for those who don't know what I mean... I can't explain here.
The verdict is still out: After shooting many RWS rifle match 5 shot groups he and I both shoot groups of 1.5 bullet hole groups at 50 yds.each. We then completely broke down rifle, cleaned and reassembled.
Then we tried Eley Force 50 ammo: This round improved groups by about 15%. But couldn't be reproduced after switching lot #'s. We then broke down rifle, cleaned and reassembled.
Next was Center-X ammo: This ammo shot GREAT... except for 1 out of 5 shots. 4 shots would share a 1.25 bullet hole group with the "flyer" being 0.5 out of a single bullet hole group.
Then the weather turned bad down here in Middle TN. and I quit trying all the other high end ammo last fall. I closed down the barn door, worked on my toy box orders and I'll resume this spring.
I never posted any pics because I thought some folks weren't interested or offended...

So here's a few and anybody who want any more info just ask and I'll be glad to post for you... Thanks, Brad
