[QUOTE="ImBillT, post: 3081689, member: 117715"] Increasing bore diameter slightly increases efficiency, so a 6.5Creed should shoot a 135gr bullet to a slightly higher velocity than the 25 Creed. That makes me wonder if it’s actually fair to compare the 6.5Creed at a full 100fps disadvantage to the 25Creed with only a 5gr increase in bullet weight. I think a 135 LRH vs a 144 LRH is a more fair comparison because the the bullet design is the same. The 140 Hybrid doesn’t have the ogive pointed like the 135 and 144 LRH’s. At a 50fps disadvantage the 6.5Creed beats the 25creed by over 100ft*lbs at 1000yds, and at a 100fps disadvantage it still beats the 25creed by 15ft*lbs. [/QUOTE]
