Ok guys. I have a 28 Nosler with 1:9 twist 26" barrel. I was having some issues finding a consistently accurate load with Berger bullets so I ordered some Hammer Bullets. The only long range buellet they have for 1:9 is the 143 grain so that is what I got and they do shoot AMAZINGLY WELL! Like under 1/2 moa at 200 yards out of my rifle! That is where I struggle. I bought a 28 Nosler to shoot heavy bullets, well heavy to me, like the 175 and 180 grainers. I shoot a 143 grain bullet out of my little 6.5 creedmoor. I really want to shoot heavier than 143 in my 28 Nosler. I see they have 155 grain that says 1:8.75. Has anyone tried those out of a 1:9? I wondering with the volocity of the 28 if it will be ok? Another question/ concern. The 28 Nosler is a long range hunting rifle. I don't see the little 143 grain bullet maintaining much energy at say 1000 yards. I can't find the G1 bc for the hammer hunter bullets and I don't know how to use G7 to calculate a ballistic chart. My best load with the 143's is right at 3400 ft/sec. can someone figure out the bullet drop, velocity, and energy at 1000 yards for me please. I'm over 1200 ft/lb and 1800 ft/sec with my 175 Berger elite hunters but they don't group great. In summary, 1. Has anyone shot the 155 Hammer Hunters in a 1:9 28 Nosler? Was it stable at long range? 2. How do I figure a ballistic table for the hammer hunter bullets since they don't publish G1 bc? Specifically the 143 and 155. 3. Would it be foolish to shoot an elk at 1000 yards with the 143 hammer hunter out of a 28 Nosler? I greatly appreciate any info/ advice.
