280 Remington Reamer and quesiton

[Heman]

Looking at trying a 280 Remington or a 280 AI for NRA Long Range. Just wondering on your opinions. Planning on shooting the 175SMK or the 180VLD. The 280 appears to be right with the 284 so wondering if the extra horsepower would be necesary.

My brother shoots a 280 for 600 and 1K NRA prone events.

It is a very accurate cartridge and gets velocities very comparable to the 284. He shoots a 30" bbl on a Pre-64 Win action.

The 280 requires a long action where the 284 does not.

There may be an advantage to the short fat powder column of the 284 but you still have to drive the bullets into the X-ring. The Indian is still the most important part of the equation.

Copy, would I be ok with the straight 280, or will the extra horsepower with the 280AI help? I shoot a 7mmWSM in Fclass and the 280AI looks to be close.

The AI might be just the little extra FPS to match a 284. My brother considered going to the AI but would have had to purchase a reamer. He is pretty happy with what he has and didn't want to spend a bunch of money on new dies and such.
