I think that the problem is that their arn't enough bullets out their to take advantage of this much powder behind this bore. A guy I know had a 6.5-300Wby for a while and his accuracy load was at a velocity around 3200fps and the accuracy started to fal fast after about 800 rounds.
If your wanting a hot 6.5 that I'd go with a 6.5-300Win mag I reload for a buddy that shoots a 25-300Win mag and its awsome the big advantage being that you can get Lapua brass,it would be a step up from the old 264 Win and with alot better brass.
I'm personaly having a 260 Rem built as we speak , I got a good deal on the barrel and I had a short and a long action so I could have chosen about any caliber but fi you look at the balistics of a 140gr 6.5mm A-max being launched at 2800-3000 fps its pretty impressive , and the barrel life will be good and the componets will also be easy to get. Maybe after a few thousand rounds I can have the barrel set back and rechamber to 6.5-300WSM.
My oppinion would be to either go up in caliber if you want to use that case or down in case size if you want to use that bullet.
From what I have seen with common bullet for the 6.5mm is that optimum velocity and accuracy can be had with a case holding around 65-75grs of powder.
Pretty well said. There is a point of diminishing returns with the respect to case size and bullet caliber. After thirty plus years of shooting 7mm's I decided the 7mm STW was the break point between velocity and practicality.
The 7mm RUM is a proven barrel burner and even with the highest quality barrels and barrel treatments I can't imagine trying to put a 6.5mm bullet in front of 90gr's or more powder. Nobody I know is making 6.5 bullets designed for the kind of velocities that much powder will generate.
I love my .264wm and got excited about the 26 Nosler but the longer I thought about it the more I knew that in the long run the benefits just didn't justify the expense.
I have 3 .260 Rem's and they make a lot more sense.
