Hello,
welcome to the forum.
You can get a reamer from Clymer (under wildcat section), Pacific tool and gages, Jgs, and if you have look in the Midway catalogue, you will see a 30.221 reamer with floating pilot.
A lot to choose from really.

Midway is selling ECT brand floating pilot reamers which are just Pacific Tool & Gauge reamers that Midway has branded with the ECT name.
Good tools!
My 300x221 reamer is a PTG floating pilot I got directly from PTG before Midway was even selling reamers.

Hello Randall,
I am just about to place an order to PTG for a 300 whisper reamer.
I had a look at different dimensions sources for that reamer and the one published in PTG reamer's specs seems quite wide (maybe for AR or semi-auto type of chamber?).
The dimensions specs in Ken Howells book about chambering reamers are a bit tighter.
I played a bit with redding reloading dies in 30/221, and made some whisper cases out of 223 cases. after mesuring them, it seems that they are even tighter than Ken Howells specs.
I am wondering wich way to go and what dimension to provide to PTG?
I will be using the whisper in bolt action rifles only.

Nicolas-

PTG's reamer book is all REAMER dimensions.
Don't confuse reamer dimensions with cartridge dimensions, they are certainly different so that the loaded cartridges will fit into the chamber.
Necessary clearances vary based on the type of action being used.
0.004" would be snug and 0.002" being absolutely tight on the neck clearance.
Factory firearms from companies like remington or winchester will usually run 0.008" or more.
Body clearances should be around 0.006" to 0.008"+.

If you have Ken Howell's blue book, it's a set of CARTRIDGE drawings, NOT REAMERS.
I have both of these books as well.
Ask more specific questions about actual dimensions and I will be happy to throw my opinions out.

I use PTG's reamer just as they suppply it with a 0.336" neck and it works fine for MOST brass.
Beware of heavy/thick brass such as Federal and maybe Lapua.
