This was 64.5 grs of Rel22 in a new Nosler 280AI case.

Just a FYI, RL22 is very temp sensitive.

Just a FYI, RL22 is very temp sensitive.

I advised my son of that the other. We'll start at about 60grs in the spring and work up again....when he gets to 3150 that should be about right.

I had a 280 built in 96 the rifle liked 57 gr RL 19 140 BT at 3008 fps. I bought a used 280 AI in 2005 and the guy was shooting the same load in it i never did chrono it because they both shoot small groups, My nephew has made some great shots it is only shot in the winter hunting season.
