Quite a few years ago a smith said that the 280 R. did not have the right throat and he knew what the right throat was! I looked at the drawings of the various cartridges and as I recall the 280 differs from other chambers.

Savage 99 - I've seen iffy accuracy out of some factory .280s, real good out of some others. A few months ago I sighted in a A_Bolt .280 Rem that I shot three 1/2" groups with factory ammo. I changed the leade angle on the reamer I had made to match my .280 Ackley and my 7mm Rem Mag. All of the .280 Rems. I've built shot as good as the Ackleys and Rem Mags. Over the past eleven years I've built more 7mm Rem Mags than any other single cartridge. They have been outstandingly accurate and of course very effective on game."
You would have to ask if the 280 is as accurate as similar rounds?
