I shoot 139gr Lapuas with an OAL under 3". This is a very long bullet and not ideal for hunting but shows you that you can stuff most hunting bullets into your mag. I think the 140gr Amax would make a great LR bullet.
The 6.5X47L works really well at high pressures. I personally don't like a hunting rd that has to work at elevated pressures. There is simply no room to account for weather.
If the rd is loaded to say, magnum pressures, it should equal a 260R at standard pressures. If you load the 260R to the same pressures, you get more performance.
There is no replacement for displacement.
I have heard competition shooters reach 2900fps in long barrels with 140gr class bullets but have yet to see that posted in shorter hunting length tubes (YMMV). Likely, the elevated pressures start to show up in standard actions limiting performance.
Most reports I have read show lighter 123/130gr bullets reaching around 2800fps and the 140's around 2650/2700fps.
I prefer using case capacity to get me my velocity in a hunting rig. Stuck bolts are no fun when chasing game.
Same issues with the 6.5 Creedmore and this is a few grains bigger.
My 6.5x47 lapua was built by George Gardner (GA Precision) on a remington 700 action, with a Mike Rock barrel at (22 INCHES) and bedded into a Mcmillan M40A1 (Marine Sniper return stock) I shoot the 130 bergers at 2970 (10 round groups under half MOA) and easily got over 3000 fps but accuracy started to degrade at 3050 + I started to get pressure signs. So it looks like the 6.5x47 lapua has no problem getting the speeds up past 2800 like you stated even with a short tube.
