My custom 280 AI

Well... just got back from setting the zero on her...
The 175ABLR and the 180 VLD show promise.
200 Yards
50 Degrees...
10 mins after the sun came up.

The loose holes:
175s -wet bore on the flyer
180 vlds - load switch
60 I7977, WLR
seating depth? Whatever I noted it was for my M48 and 140 load a while back.

Excellent!

I've been waiting to hear from a 280ai guy using IMR 7977. Looks like a great powder, did you have the chrono out?

 

[Jokostel]

Nope... the last time I chrono'd was pretty close to this temp. This rifle runs right at 2800fps with this load....
I do still have the load data from Berger for the 195s... however, this is a 9 twist Brux. I don't feel that she'd be enough. Id guestimate that those would be leaving the pipe @ 2750-2800 as well...
