I have a howa 243 and shoot factory winchester deer season xp. which seems unreliable to me. I have had good results but also had it blow up on a fallow front shoulder and didn't penetrate very far. Other times it the deer ran maybe 20m and dies.
I like it though, easy to shoot/low recoil and seems effective for realistic hunting ranges.
I have seen photos of federal blue box on deer and it's lethal so might try that next.
