Finally got my Savage 99 back after 2 mos. I had it rechambered to 250 Ackley Improved. My gunsmith tells me that his chambers are at minimum specs. So tight that I cannot chamber new factory rounds. He tells me that if it were a bolt and not a lever it would chamber just fine. I went through my loading cabinet and found 30 brand new factory cases. They will chamber but very tightly. Should I load these up to factory specs to fire form the cases or?
