Sounds great shinbone. Will be looking forward to your results.. I realize every rifle can be different , even the same brand. . My son & me both have Ruger stainless Hawkeye rifles in 264 mag. His shoots the 120gr TSX Barnes great with Rel 33 @ about 3440 out of it's 24". Mine shoots terrible groups with Rel 33, but ting groups with IMR 7828. Go figure..I will be re sighting in my EW tomorrow as I am replacing the scope rings with "Quick Release " style . Have my own range. Wish you were closer . Think it would be enjoyable working together on this project
