I have been reloading for alot of my life, but still not that experenced. I have loaded 44 mag. and quite a few 45LC , but only when I needed them.
And not being able to shoot as much as I want, well you know.
Now my question.  I'm now a proud owner of a Ruger SRH 454 Casull.  Ok, Now the question.
How much crimp is enough? And HOW do I tell when enough is enough. Or too little is too little?
On my 44 mag. I can just see a nice little roll. Is this enough for the 454.  Please help.
thanks   joe

You need a heavy crimp with the .454; about as much as your crimp die will give you without buckling the case.
Good shooting

Make sure you get good neck tension.  This is at least as important as a good crimp.

Check the expander plug and ensure that it is a good 0.004" less than bullet diameter.  0.005" is even better.  With good neck tension you can see where the lube grooves are in a cast bullet after it is seated.  If your expander isn't small enough you can chuck it in a drill and polish it down a little.

Seat and crimp in two steps.  Seat first so that the case mouth is even with very top of the crimp groove (so you can barely see the crimp groove at all).  Then, with the seater stem out of the die, crimp it until the mouth of the case actually has a little short section that is parallel to the sides of the case, but in the bottom of the crimp groove.

Make sense?  Look at factory .454 ammo... that should give you a good idea of what will work.  One of these days I'll take some pictures of various crimps and whip up a short tech note.

Marshall will tell you that the Redding profile crimp die really helps, but I don't shoot a .454 so have never tried one.  I'm sure they work great but with what I load I have been able to get by with this method.  You might need one depending on how heavy your loads are.
