Be sure to get a 7 twist so you can shoot the heavier monos. I am not a fan of the hard alloy monos such as Barnes, Badlands, PVA, and prefer the softer alloys that Cutting Edge and Hammer use as it generally yields more speed and the petals come off and do more damage. This is a ladder at 500 yards with a CEB 140 Lazer G1 .600 expands down to 1,300 fps and H1000 topped out at ~2,900 fps(you can see the different
sharpie colors on the bullet holes), I got more speed with Retumbo ~2,960 but have not shot the final two test loads for my 7 twist 6.5x284 24'' barrel. The Lazers shoot best at the lands then 2nd best at 0.025 off per Cutting Edge. The Lazers accounted for 13 of the top 15 spots in the last King of 2 Miles, maybe they sponsor everyone or give out a lot of free bullets, who knows.
