22 Cal. case mouth reaming tool

I read about a inside case mouth reaming tool that would allow the seating of FB bullets so ones fongers wouldn't get pinched while trying to seat FB bullets .
Anyone have a link or info on this ??

Wayne: If you mean inside taper neck reaming, I'll be the first to give a big thumbs up for the K&M Inside Taper Neck Reaming tool. Sells new for $28. Available direct from K&M Precision Shooting products, www.kmshooting.com (616) 399-7894, and from Lester Bruno, Russ Hayden, and other retailers. All my brass gets the one time treatment resulting in problem free seating of flat base bullets. Other similar tools are available as shown on page 31 of Sinclairs 2010-A catalog, top left of page. I prefer the K&M with the center guide pin thru the flash hole that keeps the cut straight/square, and the 3 pins in the flutes that control the length of the cut at exactly the recommended 1/32".
 
Wayne: When you get the tool and make that nice smooth entry angle on the case mouth, take one of your flat base bullets and sit it, but do not push it into the case: just sit it straight on the case mouth, then slowly rotate the case so the bullet is pointing at the floor,and I'll bet the bullet will not fall out. I've even done that with flat base bullets that have a pressure ring. Unless you are trimming your cases a lot, it will be a one time operation. One of the best, most useful tools I use. The problem with the standard de-burring tool, as made by RCBS, Lyman, etc. is that it leaves a sharp edge on the inside of the case mouth and the sharp corner of the flat base will catch, (and sometimes be damaged), requiring a lot of pressure to seat, and more difficult to start the bullet straight. Not so much of a problem with boatail bullets as the entry angle is on the heel of the bullet.
