I have a couple Coopers, one in .204 which has been a great gun for the most part and two in 6.5-284. The triggers are not bad unless you have lots of BR experience, then you won't care for them. They are adjustable however and can be adjusted. I have had one of the 6.5's back to them numerous times and will never buy another Cooper. Their customer service is lacking.
My specific issues with them came about by testing these two identical models with excessive amounts of variation using the same loads. One gun built tremendous pressure to the point it was nearly impossible to open the bolt while the other identical gun handled it perfectly. (Also tested one in Sako 85 with no pressure issues) Cooper refused to correct the problem stating only that I was exceeding the load capabilities of that gun. Funny the other one had no trouble whatsoever. I believe that due to lack of SAAMI standards on this caliber at that time allowed too much variation in reamers used to cut the chambers, but don't have any proof of that. If I were buying another one it would be the Sako 85 built by JB at Accuflite arms in PA. I am done with Cooper.
