Gun still at Cooper and latest communication tells me the wait time for them will be 16 weeks to get the barrel then shop time to chamber and fit.

I am getting VERY unhappy............................................

thanks for the suggestions.

I bought a Cooper in 204 Ruger that had a oversize chamber. I fired a number of rounds through it before I finally had enough and sent it back to Cooper for a re-barrel. Now I have a number of cases that are too large to fit the chamber in my new custom Remington 204 (an most likely the rebarrelled ...

Not yet, but I will get an answer especially if they want money to replace the barrel. I suspect the wandering reamer is the answer. Now having problems with the brass I fired in the gun fitting the chamber of a custom build 204 Ruger even after FL sizing the brass. Looks like I need a small base si...

Gun went back to Cooper who found barrel to need replacing. As they had no 204 Ruger barrels in stock, I was told 8-12 weeks, It's been gone about 5 weeks now. Time goes so slow when waiting and so fast when your not...............

I have a Cooper with a enlarged chamber that is now back at Cooper for a re-barrel. The cases have been sized in a Redding body die, but are still too large in the pressure ring area. I need to run them through a small base die. I intend to hone the neck size area out to have it as Small base body d...

Not disputing your results with Wilson barrels - after all you own and shoot them. I also own two Coopers in 17 HMR and am very happy with how the guns shoot. Actually my hope is that Cooper will decide the chamber was a factory error and they will replace the barrel for free or at a greatly reduced...

It appears that my CF Cooper (204 Ruger) will be needing a new barrel. What are your thoughts on the quality/accuracy of Wilson barrels? The company has initially quoted me a difference of almost $300 between re barreling with a Wilson barrel and a Krieger barrel. That makes me think the price of Wi...

I have a M21 Varmint Cooper in 204 Ruger. The fired cases, both factory and reloads show a pronounced bulge at the "pressure ring" of .005" more than my friend's Remington 204 Varmint. The pressure ring expands from a FL resized diameter of .370" to a fired diameter of .380"...

Rick and all, were your cases showing the bulge mine are at the pressure ring?

I have what I believe to be a early Model 21 (SN is two letters followed by 2 numbers) chambered in 204 Ruger. The fired cases, both factory and reloaded, show a pronounced expansion (.005" greater than a case fired by a Remington 700 in same caliber with ammo from the same box of ammo) at the ...

Anyone on the Forum hunt varmints in Arkansas?

Please contact me as I am interested but the game we can shoot seems very limited.

A friend and I bought 1000 Win new 204 Ruger cases. I weight sorted them and did a quick quality inspection. 20 of the cases are defective. I have emailed Winchester with no reply as of yet.

I am a very persistent guy and WILL be following up.

The large ES's were with the same load, cases, and primers. I haven't tried 27.5 of 8208 so I might give that a try. I'm looking at using the 204 for prairie dog hunting so the ES's should cause vertical dispersion at distance - at least that is my experience with shooting other guns in NRA mid and ...

Did a search and read most of the posts with no epiphany. I am a experienced reloader but new to the 204 Ruger cartridge.
