I have been doing a bit of work lately with some 156 gr Norma Oryx in my 264 WM and Retumbo. Haven't chronographed it yet but 64 gr of Retumbo in W-W cases and CCI 250 primers grouped pretty good out to 300 yards. It's holding around MOA from field positions like shooting from a stump. I'm kind of surprised it is doing as well since I have some throat erosion but I can seat those long 156 gr bullets way out there.
Since it looks like the barrel still has some life in it I need a few ideas. The box of 156 gr Oryx bullet won't last forever and are tough to get in these parts so I am thinking of trying the 155 gr Mega combined with the 160 gr Matrix. Not sure how well the 160 gr Matrix will do from a 1 in 8 twist but maybe someone here has tried them.
Option #2 is try the 140 gr Partition again, with Retumbo or Magnum I could never get consistent results so maybe something like IMR 7977 or IMR 7828 ssc would work.
Option #3 is something like the 127 gr LRX or 120 gr E Tip since they can be loaded out closer to the lands.
I'm kind of leaning towards option #1 and the heavyweights since the Norma Oryx is doing pretty good.
And thanks again to Jamilla for the kind gift of those Oryx bullets and to Scotty and DrMike for getting them across the border. Within the next month the freezer will be full again of some nice bear meat
