Thread: X-bolt chamber throat

Does anyone know if the browning Xbolt target max has a short/standard throat. The barrel is a 1:8 so I assumed it would have a throat optimised for 70+gr projectiles. Problem I have is during load development with 75gr bullets, at full mag length coal I am well into the lands!?. Makes no sense to me. Great rifle, shoots amazingly well with 55gr but I want to shoot some long range steel. Any ideas?
