I've found that generally, a rifle looses ~30 fps per inch from 24" down to 20", and then 50 fps an inch when going shorter. So a 24" .270 will loose say 400 fps, which would have your 130 gr loads in the ballpark of 2600 fps.

If you look at Hodgdon's data http://www.hodgdon.com/data/pistol/308win.php
a 15" .308 will push a 130 gr bullet 2700-2800 fps. With Barnes 130 gr triple shock, you'll get terminal performance on par with a 150-165 gr cup/core bullet. I would certainly consider the bullet capable of 300 yd shots on deer. That said, it takes alot of practice to be able to make such shots in the field with a scoped pistol. It is much harder to shoot a scoped pistol as accurately as a rifle in the field.

I agree with Ken, the .270 is a fine rifle round, but a poor choice in a short barrel. Look at what cases perform well in shorter barrels, and it will be those with larger bores. The .308 performs very well in shorter barrels.
