100 fps variance per inch of barrel is not right … either different bores/dimensions, different lots of ammo or something. I d guess 18-20 fps difference per inch on a cartridge shooting roughly 2600-2650 fps.
Sorry I m late responding but my sporter barrel doesn’t heat up very fast 5-6 rounds and it’s nothing close to a 6 CM or 243 firing some number of rounds.
