Short barrels do not kill accuracy and depending on cartridge, velocity may not suffer as much as people think. For the yardage you are shooting I would go with a bull barrel in the 18" to 20" length and any twist you wish. ALOT of people are going to tell you that you need a 1:8 twist but for 300 meters and in that simply is not true and at those distances a slower twist using flat base bullets usually give the better accuracy. I shoot a lot of short barrels out to 1K and have not had an issue with accuracy.
