Re: chamber reamer drawings
I have loaded for and messed with three different brand 300WSM. A Browning A-bolt, a Tikka T3, and a Savage that I don't recall the model no. Every one of them had a tight chamber, and I seriously believe this is the nature of the cartridge. These WSM's are high pressure rounds and if I were you I would be very careful trying to encroach the lands too much. All the above mentioned rifles were handloaded using 165 grain Hornady boattail bullets.
