350 Legend Reloading

Anyone willing to share their most accurate load for the 350 Legend? I’m clueless on bullets, powders, weight of powder/bullets primers, and cases.

I smoked 2 deer with Winchester xp 350 Legend 180 grains in my AR15 but 1.6 inches at 100 yards is not a tight enough group for me. I’m not seeing people actively working up accurate loads for them.

I did not retrieve the bullets from the deer for performance assessment. 1 doe was a head shot right through the ears and was dead instantly. the other was right behind the heart and only made it 50 yard before falling over and dying quickly.

Thanks
