Re: Recommended chamber reamer for 300WM & premium factory hunting ammo??
Don't even try to get 'fancy' if you'll be shooting factory loads. I'm currently "tusslin'" with one I built to minimum head space dimentions (GO gauge + a .002" steel shim and the bolt won't close). It'll except my handloads built using new Nosler brass, but won't except every factory loaded round I try. Some will chamber, some won't even come close to chambering. These factory rds. were manufactured by Remington & Winchester, and are of current manufacture. The chamber won't except full length re-sized brass fired in another rifle. No surprize there. There's just too much variation in the size of factory produced ammo to expect a tight, but in spec chamber, to except any and all of it. My solution to my problem, as my customer isn't a reloader,,,,,, increase head space toward the middle of the tolerance...... Not an 'ideal' situation, IMO. "Everyone wants to 'drive nails',,,,,,, not everyone is willing to custom taylor their ammo to their rifle to do so."
"Shoots real good!": definition; it didn't blow-up in my face. Not everything can be fixed on an internet forum!
