I used IMR4895 because I had a couple pounds of it and I don't use it with anything else. 23grs is very accurate, but slow at only 2668fps from my 22" barrel. I've shot about 60 rounds at 400yds with the 68's and decided to backup to 620yds today. I had 30 rounds with me and I missed the 1st 3 shots because I over dialed. I don't have any wind flags out but I'm shooting down a big lake so I try to watch the water and make a SWAG on where to hold. I ended up 22 of 30, it sucks I missed the first three on a dialing error. I did not have rear bag and was using a 6" - 9" bipod on the front. It was 87 degrees by 11 o'clock so 30 rounds was enough.

I know this isn't much of a group so don't laugh me off the campfire.
