280AI

Having something somewhat silly built.

Anyone have a 280AI with a 28+" Barrel and want to share some load data and velocity?

Thanks!

Lobbin big old footballs.. sounds like fine. 160 gr partition and H1000 works good 4 me. 190 would be cool

I’m shooting them - Berger 190 LR HT from a 284 Win 32 “ 5 R 8.5 twist at near 2800 with 55.5 gr H4831SC F210M .
They pretty much shoot exactly the same as Berger 184 F open HT Bullets .

I've thought about a crazy long / heavy 280AI...nice to see others doing the same

My 190gr A-Tip N565 load does 2626 fps from 22.5" barrel, a 32" would give 2837 fps according to Quickload software. That will stay above transonic to 1650 yards (2500' ASL / 0c) Lots to like there!
