RE: Ruger question..........
Schoolcraft...Every factory rifle needs work on the trigger to get it down to a nice crisp 2 1/2 - 3 pounds, that is not at all unusual no matter who makes the rifle...
In our family of hunters we own all 3 brands that you list...I have done the trigger work on most of the Remingtons...They are pretty easy to do, but personally, I shoot a Ruger .243 and my brother shoots a .270, both shot as well as like rifles in Remington and Browning (after you find out what brand ammo they prefer)...
