I can't give you any advice about the .308, but I have been using the 160 gr Accubonds in my custom heavy barrel 7MM RM. I currently use 59.0 gr of IMR 4831 and WLRM primers which is not very hot, but it shoots ok out of my gun. I have not experimented with it since I loaded those up but if I remember right, it's shooting under 3/4 to 1/2 MOA without me going back and checking. The velocity is only a little over 2850 fps out of a 26" barrel. I was always going to try the Berger VLD's but when I was shooting the 7mm I couldn't get my hands on any of them. RL-22, or IMR 4350 also shoot good out of my rifle.
As for cutting off your barrel.... I can't remember how many fps in general you gain per inch but I thought it was somewhere around 100-150 fps or so, and I don't know how fast you can push that .284 bullet out of a short barrel like that ether. I would think that it would not be too much below what the published numbers are.
The bottom shot was to get on target, the top hole I'm claiming as a "Flier". This is my 7mm Rem load with the 160 Noslers.
I'm sure someone else will chime in with some further information. Hope you didn't forget the seater dies!
