I have a .280 Factory Sporter Remington in a McMillan Standard fill Hunter pattern. It weighs right at 8lbs with scope. I have ordered a Bartlein #3 for it that is slightly smaller than the factory barrel. Finished at 24", it should weigh in at about 7 3/4 lbs and will punch it to .280AI as well. Not sure but I may have the bolt and barrel fluted by Karl. Should bring it down to 7.5 lbs.
