Scored me a lefty the other day, now I have started putting together dies , cases , factory loads etc. powders I have on hand  rl 22,23,25,26. Imr 7828, retumbo very little, us869 and h1000. Have 180 grain scirocco, partition, accubond and fails safe. 200 grain partition and accubond. 210 grain long range accubond. Any load info would be greatly appreciated as I really don’t know much about this cartridge first hand.

I am using the 200grn LRX on top of 107 grains of AR2225 (Retumbo) for right around 3300 fps. I have also used that load with the 200 grain Accubond. They both shot equally into less than .5 moa but I went with the Barnes as I am a Barnes fan.

Shot her today, thanks to a accubrake she’s just a big ol pussy cat. Started with factory ammo to get on paper, then to loads with nosler once fired brass. Forgot the chrony at home. 91 grain of  rl 25 produced about 1.25 three shot, 92 grains was better like an inch but point of impact shifted. 93 grains was .75”. 200 grain partition. I am happy so far.

That's good to hear you got her shooting nicely. Pop that muzzle brake off and she is still a pussy cat. Maybe one the size of a tiger but a cat the same haha
