Load Data for the 40/60

I wonder if the the Redding profile crimp die for the 40-65 would work?

Accurate 41-210C is what I use.

Does that one hold enough lube for BP?

Hey King, i'm still molding & shooting the old Lyman 403168, mine weigh out at .215+-, .406 dia. & 1, mould that drops at .215-216, at .407 dia. Both hold plenty of lube, if i want to PC some i use the .406 dia. oh!, i shoot smokeless.

  coffee's ready,  Hootmix.

Since no-one has answered you, I will try an explain it with measurements and experience from playing with dies and brass, from both the 40-60 Win and 40-65 Win dies that I have messed with.

A simple answer to you would be 'No', 40-65 is 2.1" COL while the 40-60 is 1.87" COL, die is to long to crimp a 40-60.  But 'maybe if' things have different measurements from what I am using and you are willing to get into a lot of work.

1. The ideal of the profile crimp is that the neck diameter is tighter than standard dies to restrict or resize bulges.  The neck diameter of the 40-60 brass is 0.425"(my measurement from a formed 45-70 through an RCBS trim die), while the neck diameter of the 40-65 brass from a formed 45-70 through a 40-65 RCBS sizer is 0.422".  So the tight profile ID neck may measure 0.423-0.425 (??) this would still make the die just too tight in the neck area for the 0.425" 40-60 casing unless you can lathe polish the neck 'just right'.  THIS IS THE BIGGEST ISSUE THAT I WOULD INITIAL WORRY ABOUT WHEN STARTING THIS PROJECT.

2. You are starting with a die made for a 2.1" casing minus the base thickness and have to cut down for a 1.87" casing length minus the base for a final.  This mean grinding, cutting or lathing off the bottom.  Also include the thickness of the shell-holder lip.

3. Both casing have about the same base diameter at 0.504".  So as you cut the die shorter the mouth of the die has to be re-ground back to the original 0.504" diameter and tapered for the 40-60 to fit and reach the dies original crimp step.
I did this on a RCBS 40-65 Win seater in a set that someone already had converted the sizer to a 40-60 -- 0.350" neck.  They stopped at that point, so 'as I had bought it', I did the seater conversion so that it crimped a 40-60 brass.  Polishing the final ground die took the most time.

One other thing you may have to determine is what neck length your rifle chamber is cut for, 0.350" or 0.450".  These measurements are info that was given to me while talking to Slamfire.

I think this gives you the worst points that have to be addressed.  Hope this help you out 'somewhat'.  It appears to be a job.
If you really need the Redding Profile Crimp die you may be better off having Redding do a Custom die.  I don't see or have ever needed the profile crimp for any rifle caliber.  I guess I am just lucky with bullet diameter, correct neck expansion plugs and seating slowly.  I always seat and crimp in single press.
Me, I will stay with the standard seater.  The wikipedia spec for 40-60 Win shows the neck diameter of 0.425" with a bullet diameter of only 0.403".  My Win Original mold drops a 0.402" - 0.404" bullet, I will size to 0.403" and load.   
If I can find a 40-60 rifle.
