Ive got one , and its not grouping to my likeing with 250 grain bullets .Im going to try 300 grain sst's and harvesters next , and if they dont group , 295 powerbelts . Of all the 250 grain bullets I put through it it liked the powerbelts best , and they loaded easyer for me allso . The 250 powerbelts grouped just over 4" at 100 yards .
