Whats wrong??

[Malibumick]

I have a buddy that got a new Remington R-25 shoots 1/2 moa first 4 shots then shoots softball moa after that. Replaced the factory POS trigger tried different loads, 3 different scopes same results. I know the chamber gets extremly hot. Is that our problem or is it something else. I have little experience with semi autos and don't know what the next step is to try. Thanks

The group will spread out as they heat up...dont know about going from .5 to 4".

How fast are you shooting?

Somethings not right. My Rock River M-4 Style shoots 1/2" to 3/4" from 1st 5 shot group to the last at 100yds. But I've always been told all guns(barrels) are not alike. Some shoot well cold, some hot, some clean, some fouled.
