stanW,
I'm just now starting to practice more at longer ranges. My encore 30-06 barrel is in the corner right now, but after muzzleloader season gets over it'll go right back on. My last load development for it was using 150gr barnes triple shocks over IMR 4350. I increased the powder by .5gr increments until I was way over the maximum in any book and I physically couldn''t get any more powder in it.
Strangly enough, I didn't get any excessive pressure signs while at the range with this experiment. I was carefull and worked my way up, but I was amazed that I didn't even get overly flat primers. My next reloading session with the 30-06 will be to load up a lot of 150 gr bullets just off the lands for my 30-06 and see start working my way back up the pressure ladder. I want sub MOA groups out of this rifle so I can use it for longer range target shooting/practice. I've got some SST's to try out, hopefully mine do as well as yours did.
