From what I read 800x was prone pressure spikes and doesn’t meter well. So I went with longshot
That is correct, 800X meters like cornflakes. If you want to run max loads with it, it's best to weigh each charge, because they can vary a lot. Blue Dot is better but still not great. #9 and #7 meter the best, with Longshot and Power Pistol pretty close behind; all four of those meter nicely.
