Just wanted to share this with the members. I have a .280 improved that I had built in 1996. I shot mainly 160 game kings in it until recently. I have been preparing for a whitetail trip to Kansas this December and decided to make a change to the Berger 168 VLD Hunting bullet. My barrel is a Hart 1 in 9 1/4 26" tube. I have developed a very accurate hunting load for this rifle. I'm shooting Norma brass, CCI Magnum LRP, 62.5 gr of Retumbo and of course the Berger 168, .040 off of the lands.
I'm not a speed freek, more concerned about accuracy. However after shooting this load on three separate sessions to verify the results, I set up my chronograph on the 4th and 5th sessions and was surprised at the results. I set my chronograph out at 15 measured feet from the muzzle and shot 12 shots each session, 2 Saturdays in a row. I averaged an unbelievable 2946 fps on the first day and 2944 on the second day. No pressure signs with this load in my rifle and I stress again my rifle not yours. I am not recommending this load for anyone or saying that it is better than yours or any out there. I got the load from the Hodgdon site and I am not shooting the max per the site.
Has anyone else out there shot this combination? By the way the temps each day were about 85 to 88 degrees, 1180 ft elevation. Kyle

The 280 ai is a great round, I have thought about rebarreling a savage to one many times, I have always heard that ai rounds show pressure signs quickly when they do,,, glad yours is shooting so well for ya.

I have not shot the Berger but Matchking and A - Max bullets do well with RE-22, H-1000, or H4831SC in mine.

My 280 AI likes 60.5 of H1000 with the 168 Berger. Another "go to" favorite is the 140 Ballistic Tip with 58.5 of IMR 4831. Primer of choice is the Fed 210M.

Mine is scary with a 140NBT also but with RE-19 and 22.

I have decided to re-chamber my .280IMP to 7mm Rem Mag and my Redding dies are in the classifieds.
