Hey guys, having issues with Accubonds and was wondering if anyone has seen the same. I've been shooting them for years both factory loaded and handloads. I love the performance of the bullet on deer. Never had an issue, but now i have an antelope hunt in August so i've started shooting them at longer distances. At 100yards they shoot one ragged hole but at 300 they're shooting 3-4 inches. I tried different powders, worked from bottom to max loads and still cant find a load that shoots good at distance.

I'm weighing the brass to get the most consistent , tried GM210 and CCI primers, tried Varget and RL 15 powder. Different bullet seating depths.

I know the rifle is capable because i can stick a few Gold Medal Match bullets in the gun and shoot sub 1 inch at 300yards. I'm at a lost. I have some Barnes X bullets on the way maybe they will do better.
