I have a .264 Win Mag, and can't see where the improvement would be. PTG would make you the reamer. If you want to improve the .264, the best way to do it would be a .264-300 Win Mag as it would bump the shoulder up and still fit in a standard magazine. There isn't enough taper in the body, nor a gentle shoulder on a .264 to go with the classic Ackley Improved formula and see any gain. My solution was to just run a longer barrel. I can get 3200ish with 140s, 3375 with 130s, 3500 with 120s and 3700 with 100s with my 27.5 inch Lilja barrel.
Thanks for the reply, I just worked up a load with my 26 inch barrel with 120's at 3275, I think I could actually get more cause I'm not showing any sign of pressure yet. I am using 66.5 grains of reloader 25, I think I could go with about 67 or a little more. If I shoot out this barrel I will replace it with a longer one. It groups so well that I can't relplace it yet. I have gotten consistent .5 inch groups with it. I did run those final finish bullets thru it also. It is so easy to clean now also.
Every year my Pro-Staff and I head to the woods to hunt the old wise Tom. We travel thousands of miles covering numerous states hunting these old guys. Lots of times we end up hunting public lands or private property that have been hunted already. That’s the last thing you want to hear when you just traveled 6 hours that someone else has already hunted the property. We had to come up with a game plan and one real fast.
The first thing we did was ask the farmer were they usually see the birds in...
