Re: 300 grain SMK
This is an easy one. If you want a reamer with that throat cut made, simply make a dummy cartridge at 4.000" oal. Then send it to Dave Kiff at Pacific Tool & Guage 1-541-826-5808. Dave is great to work with, just tell him what you want and bam it is done. Another option is to get a throat reamer in .338" this will allow you to set the throat where ever you want, it will also allow you to clean up the throat as it gets some miles on it.
