My Sendero 300 RUM never shot much under an inch with any bullet/load combo I tried. Sent it back to Remington for warranty work, which they accepted, but it didn't help much. (BTW, Remington's 1 inch guarantee is measured for only 3 shots from nearest edge to nearest edge, not center bore. What a difference that makes in group size) The best use I found for my Sendero was as the down payment on a custom rifle
Glad to hear that not everyone had such a poor experience with their Senderos.
