For whatever my opinion is worth, you are by no means flaming Cooper nor should this thread be altered/removed. I have several of their rifles and have had good experiences - that doesn't mean they are infallible. Experiences are only "facts" to those who have actually experienced them....

I am not a fan of removing issues that people have with products (if they are being fair, as IMO you are) as this sacrifices the credibility of everyone's opinions and experiences. I want to make decisions on what to buy by measuring everyone's collective experience (and make my own decisions on who is credible).

The flip-side is that it is important that you follow up as well - when you identify the issue/resolution please post it so we can collectively get a little smarter. I think you are going to find a smoking gun somewhere outside of load development but we'll see (I'm wrong a lot)

My editorial for the night

I only tried Remington standard 140gr factory ammo. However, as i stated earlier I did expect better from the few handloads I assembled, but as I also stated, maybe I expected too much?
I guess my colleagues opinion was that with an equal amount of time, effort and expense on components he could have gotten a Remington, Winchester, etc. shooting equally well.
I tend to agree, as most folks purchasing a synthetic Cooper are doing it for their reputation for accuracy.

Re: Cooper - Headspace?

I did post this in your other thread but will say it again. I have the same gun in 6.5x284 and was having the same problem. I was using 140 accubonds and shooting .5" to 1.5" with 2 different powders and several different OALs....switched bullets to the 140 berger and instantly went to shooting .25 to .5 MOA. How many different bullets have you tried? Also I wouldnt expect regular factory loads to shoot any better that 1.5" anyway....call cooper and ask to talk to the guy that does their load development. I spent 40 min on the phone with him and he was very helpful.

Called Cooper. They said these rifles should not be that fussy and that a lot of the Akley Improved calibers will shoot fireforming loads, right from the get-go, better than what I'm seeing. Returning the rifle to Cooper.

Hope they get it right for you! Let us know when it comes back, how long, and how it shoots.
