Thanks for all the feedback guys, much appreciated!
Crane, the 25 STW would be a smoker but I think it would be just too overbore and I dont favor belted cases. I've read some intertesting stuff about I7828 and it might be worth trying.
BillR, thanks for the tip on the neck chambering. I'll keep it in mind. I tried Retumbo in the 25-06 which gave me 3300 fps with 110 AB's but RL17 beat it by 200 fps with the same bullets and good accuracy.
Mike33, I would compare RL17 to H4350 but much faster velocities. I would recommend about 1/2 to 1 gr higher starting load with RL17 than H4350.
Rich, What is the 6.5 Sherman? It sounds interesting but I like the idea of going with the 65.-06 AI because it matches the 25-06 AI kind of and I can use the same dies. If I got a lot of 500 Lapua brass I could separate in half by wieght. Would I get 6% more capacity or 6gr more capacity? From what I can gather it might be 6 grs and 10-11% more capacity??? Since you've shot both extensively you should know. I may be interested in that Sherman reamer, ya never know.
Thanks for the offer.
Thanks for the input and keep it coming. Also read somewhere that the sharper AI shoulde was better for case life???
