Heavy Bullet creep in 44 REvolver
« on: February 21, 2006, 11:26:21 AM »
I loaded a cyclinder full of 300 XTP rounds [21.5Gr H110 and CCI 350 primer] and shot four times. Took the unfired round out and the bullet had jumped forward about 1/16".

Guys and gals...I crimped the heck out of these rounds with a Lee Factory Crimp Die. The case was compressed into the cannelure from top to bottom and it still was not enough. Any suggestions?

The loads shot very accurately and I want to keep this load if I can, but I don't want the bullets jumping even the slightest bit if I can help it.

New crimp die [Redding Profile]?
Smaller expander?
Glue?!!!!

If you'll throw away that silly excuse for a die set from Lee and get a die set from Hornady, RCBS or Redding that will not open the case back up too much for a tight hold on the bullet and then to a roll crimp you'll have no more problems.

The primary holding force MUST be a tight fit of the case to body of bullet. Then a roll crimp should be applied for a wee bit more help but the fit of case and bullet are what is the primary holding force.

I am actually using a carbide die set from RCBS, but crimping in a separate step with a added Lee Factory Crimp Die.  Sorry I did not mention that originally.

...maybe I should try polishing the expander die so it does not overexpand after resizing?

I'll bet you 10 gazillion bajillion cups of coffee (or one really good chocolate chip cookie) that it has something to do with your Lee equipment. I have had utterly vexing problems like that with Lee equipment and have sworn off any further use of their products.

Try seating the bullet without using the expander die at all.  Crimp in a seperate operation.  Also, which crimp groove are you using?  If you are using the top groove you are putting in too much powder.

without expander

Bob,

Nice hearing from you.  I hunted with you at White Oak back in December and got to shoot your Wyoming Express...Fun!!!

If I do not run the expander plug down in the casing it will not have any flare and the bullet gets hung up on the case mouth.  Is there a die that can flare the mouth without expanding the rest of the case?

crimp groove

Oh...forgot to answer that I was using the bottom crimp groove.  I was surprised to find out that the XTP seated out that far would fit in the FA83 since I had been told it would not since it was a "short" cylinder.  I guess it is shorter than the Redhawk and Super Redhawk, but still long enough for all I can do with this bullet.

I seat jacketed bullets quite often without using the expander plug.  The primary use of the expander plug is for cast bullets.  Typically you will want the inside of the case after sizing to be a minimum of .003 under bullet diameter and a maximum of .005 under.  When seating the bullet if the case inside diameter is .005 or more under bullet diameter then the bullet will stretch the case beyond the yield point so the case doesn't hold the bullet as well as it should.

You might just measure the nose diameter of your expander plug.  That will give you a clue as to what is happening.
