[QUOTE="Mysticplayer, post: 36044, member: 8947"] I have run a 30Gibbs and it is one of my favorite wildcats. There is an increase in performance and that is sig when ranges get out there. I have a slow '06 at 2750fps for 165gr bullets. My Gibbs took the same bullet to 2950fps accurately. Could go faster but then I had a shotgun. My guess is that your 28" tube would be around 3050fps with the 165gr bullet, and close to 2950fps with the 180gr. Very close to the 30 WSM and 300WM. With the lower BC of these bullets, I liked the idea of reducing wind drift and increasing impact vel/energy. Small but a definite difference. You gain another 100yd in performance. Same reason why people use the 300WM. There really is only a small increase in vel over the '06 but that has not detered the thousands who use it. I have sold my gibbs and replaced it with a 6.5-06. The reason, wind drift at ranges beyond 500yds. As good as the 165gr SST is, the 140gr SST is head and shoulders above it. At basically the same muzzle vel, the 6.5 is hitting harder at all ranges because of higher retained vel. The reduced wind drift is amazing. Comparing the gibbs and '06, I would go Gibbs. Between the 30Gibbs and the 6.5-06, 6.5 all the way. I would have built a 6.5Gibbs but my action will not feed the sharp shoulders. A 7mm Gibbs/280AI/7JRS would also be on my possibles list. Something to think about if you haven't bought the barrel yet... Jerry [/QUOTE]
