[QUOTE="Topshot, post: 420229, member: 13285"] The 250 grain Hornady BTHP match bullet has been available for years. I live down in Australia and have no trouble getting them. They have changed the design of the bullet slightly in recent times. I have both the old design and the new design. The new design comes in a glossy box with a picture of a bullet on the front. The old desigh is in a matt red box with just Hornady printed on it. The old design had more of a secant Ogive and smaller Meplat than the new design. The new design seems to have the meplat uniformed. They seem to change a bit from batch to batch. The new design has a published G1 B.C. of 0.67. I tested the old design at a starting M.V. of 2650 and it tracked perfectly with a G1 B.C. of 0.63 out to 1000 yards and agrees very well with Bryan Litz G7 B.C. that is published in his book. Out past 1500 yards at a starting velocity of over 3000 fps I found it actually shoots somewhere in between the Hornady G1 B.C. of 0.67 and Litz G7 B.C. of 0.323 in my rifle. I didn't bother to work it out exactly as I don't hunt at that distance but noted it in my log for future referance. I think when shooting at that distance you would want to batch your projectiles so that they are all from the the same production run. Do the numbers on this bullet. It is quite impressive. [/QUOTE]
