Back when Sportsman's Warehouse was still in Wisconsin, I bought a box of CCI 22 wrf to try in a Marlin M 25 22 magnum. The Marlin was reluctantly sold to me by a friend who warned me he could not get any respectable accuracy out of it with any 22 mag ammo he tried. The CCI 22 wrf ammo was outstanding. Group shrank by so much I was stunned. Literally from 1 1/2" AT 25 YARDS, to about 3/8". I shot a few in a stainless Ruger single six convertible and did not get a similar improvement.
I called CCI and talked to a woman, who was one of the most knowledgeable techs I have ever had he pleasure to talk too, who explained several things to me. First of all she knew all about Marlin micro groove and told me she was not surprised at the rifle's improvement because the bullet they load into the 22 wrf is a Speer Gold Dot jacketed hollow point that measures .2265" and it fills the micro groove. That Marlin is now deadly, so good I sprang for an after market trigger. It is my go to, something needs killin' in the yard/garden gun. Target out to 60 yards is the eye ball.
Now as to the revolver warning. While the tech had me on the phone, she chastised me for shooting them in the Single Six, asking me, "Didn't you see the warning on the box?" Well actually, no I had not. She went on to explain that CCI had to replace some bulged barrels on some revolvers after the jacketed .2265" Gold Dot stuck in the bore and the shooter fired another round. The worst example she told me of consisted of a Colt shooter who finally stopped when the 7th round bridged the barrel cylinder gap and tied up the revolver. Apparently the over size for convertible revolver barrels bullet sticks and the gas vents out of the barrel cylinder gap. The warning helps CCI avoid paying for repairs.
I went back to Sportsman's and bought a brick of 500 for like $67.00. I ration them like gold.
Sorry for the long winded post but that's the story.
