[QUOTE="Korhil78, post: 2248161, member: 34818"] I don’t really care too much. The thing that I was worried about was having the 1800 FPS velocity at impact which is what hammer hunters are supposed to need to open reliably. Now you can go about retaining that 1800 FPS at longer distances by using a light bullet and pushing it really fast which I didn’t want to do or you can play the numbers game with heavier weight bullets and see where the impact velocity goes below 1800 FPS. I chose to go with the heaviest bullet I could that would give me 1800 FPS impact velocity at my required distance (800 yards). Being that I could only push the 169 Gr hammer hunter to an average of 3120 FPS at the muzzle, I am then relying on BC to be my friend and help me retain that velocity to my desired distance. Even though I had to lower my BC to .237 from the estimated .285, I still have an impact velocity of 1800 FPS all the way out to 865 yards based off computer calculations. The only reason I wish I could have kept .285 BC is that my velocity would have been even higher at 800. Keep in mind that BC is going to differ even if ever so slightly from barre to barrel. That’s why you have to verify everything by shooting it at the longest distance you plan on shooting. With the Hammer hunters supplied BC from their website, you have to take that as a starting point that will help you get on paper at distance and adjust if from there. When they give you an estimation, it’s not for one to take it as if it’s written In stone. [/QUOTE]
