Sorry to disagree, but Barnes loads are, if anything, conservative.
All these computer programs are nice but there is no 88,000 psi load anywhere in the Barnes book. Suggest you call Barnes and talk to Randy to get some real facts.

At 88K you'ld need a hammer to open the bolt and the primer would be nowhere to be found.

A chronograph is the best way to test loads. Once you equal the max velocity quoted with no pressure signs, it's time to stop.

Since 2230 is the slowest powder listed and 27-2800 with a 185 TSX in a 338 Fed is no sweat due to the bullet jump dropping initial pressure, I think your software is wrong.

4895 can get 2700 at 58.2K PSI (see Hodgdon site).

If you are concerned, start with your AA book data and work up 1/2 gr at a time behind a chronograph and look for pressure signs. Maybe Barnes had a smooth, loose barrel and we know it was 24" long.

My Kimber 338 Fed sure liked that 38 gr load of 4198 behind the 185 and it was big Elk medicine.
