VLD champfer

[tenring]

I love my RCBS Casemaster. Saves a lot of wrist grease. The factory 32 degreee inside neck champfer is uses,is OK for most seating operations, but not for VLD bullets. A very steep angle is needed for those, say 7 degrees or maybe 11 degrees. I don't want a hand operated champfer like the Lyman or Holland. Where can I find a sharp taper champfer threaded to fit the Casemaster? I do have an old dull RCBS champfer. Could a machine shop re-cut it to my desired taper? Thanks.

I think Lyman makes a hand kit that screws on to an electric screwdriver i think they have a sharper cutter. the other option is buy a K&M inside neck reamer and drill and tap the alloy handle then use one of the hex studs that come with the RCBS prep centre that is what i have done. the tool is still adjustable for depth and a lot quicker to use.

Gene,

I have one of the K&M hand units. It's down side is you have to initially adjust the depth of cut. Not a big deal if your brass is fresh trimmed all to the same length, but if it isn't you'll get variations. You have to use a light touch since with that angle it can be a little "Grabby" at times.

I also have one of the K&M long-nose deep-angle cutters. I found it difficult to control the amount of brass removed. Cut just a little bit too much and you reduce the neck tension dramatically on the first 1/4 of the neck. I went back to using a std Forster chamferer, even with VLDs. I just run a little scotchpad over the chamfter to smooth the edge. I find the Scenar 105s seat just fine that way.

I know one guy who took the head out of the 28-deg Holland unit and chucks it in an electric screwdriver.

Another guy has created a fixture to hold the holland tool:

The Lyman reamer will screw onto an RCBS Trim Mate Case Prep Center,http://www.rcbs.com/default.asp?menu=1&s1=4&s2=4&s3=39). ,The Casemaster is the dial indacator type multipurpose cartridge and bullet measuring tool.) Just get a spare screw with the appropriate thread. Think the one I use is the one that came with the reamer/handle combination.

Asa - Thanks for the note, but the Casemaster does not have a dial indicator,refer to the RCBS pic at that web site). I might look at the Lyman. I am mindful of Danny Reever's advice that at even a slow turning speed, the champfer might grab; and moderator's advice as well. Appreciate the imputs.

Gene,

I'm with Mr. Moderator on this one. I too have gone back to the standard Forrester tool. I power everything with my Wally World Black and Decker rechargable screwdriver,$14.59). I have the Sinclair power adapter for the chamfer/deburring tool and the power adapter for the primer pocket uniformer makes these chores simple.

I also think that Kens debur tool is a little "grabby" and can easily chew off too much brass.

My try DULLING the flutes a bit -- gotta think that will help.

FYI - RCBS Case Master shown below:

From the RCBS webpage,http://www.rcbs.com/default.asp?menu=1&s1=4&s2=3&s3=29):

CaseMasterâ„¢ Gauging Tool
A quick, convenient way to determine several important case and cartridge dimensions. The CaseMaster gauging tool measures case neck uniformity, case neck thickness, case length and bullet run-out. All are important to accuracy and safety. Detects case head separation before symptoms are apparent on the outside of case. Much quicker than a dial caliper and makes a tedious job simple and less tiring.

The measuring/display device on the unit above is a dial indicator.

This is NOT a Casemaster:

Trim Mateâ„¢ Case Prep Center
Case preparation just became five times easier and faster with the Trim Mate Case Prep Center. Five gear-driven rotating heads turn the tedious task of chamfering, deburring, primer pocket cleaning, military crimp removal and flash hole deburring into child's play. The tough, high-torque motor does all the work, allowing you quick case movement from station to station. There are also two stationary positions for case neck brushes or other useful accessories and a cupped area for securing dry case neck lube. The Trim Mate Case Prep Center includes large and small primer pocket brushes, inside chamfering and outside deburring tools, medium and small case neck brushes and a packet of dry case neck lube. There are also a number of optional accessories available.

Sorry Asa, you caught me with my head turned round; you are correct; Casemate it is.
