No. Lee makes one for the 240 weatherby mag and they have it in stock on their website240 Weatherby Custom Factory Crimp Die - Lee Precision
Each to their own but crimping will never produce as accurate ammo as no crimp, especially in bullets without a cannelure. I have never found a reason to crimp anything other than some pistol rounds and that is a taper crimp.

Thanks FNA3G and I agree about the crimpping deal. Have never really acomplished much by adding a crimo to the process...But for some reason this gun likes a little higher pressure...I think.. I got the bullet depth set about the dia. of the bullet right now..I started out touching the lands and have now backed all they way down to like I said about the diameter of the bullet and seems to be the best groups now out of all of the depths in between besides the group touching the lands and I don't like loading bullets touching the lands, just don't feel safe doing that, and thats just my opinion don't mean it's right just don't like doing it. The groups opened up the first .020 off the lands. I started sinking the bullet in .020 and load 5 rounds. And each time my rounds got a little tighter but lose about a inch in elevation. So now witout touching the scope elevation I went from toughing the lands and almost 6 " high @ 100yrd to now about 2 inches below the center of the target but good groups. I was hoping to keep this depth and group but gain more elevation by adding a small crimp..Probally won't work or help me but I'l never know if I don't try it..The whole purpose to this is to be able to shoot a little further and keep my tighter groups before it starts to drop like a rock and have a little know down power left..
It is not uncommon to have the groups move with different loads. Why not adjust the scope to move the group to where you want it?
Crimping is not going to help. I would suggest that as you seated the bullet deeper into the case the group size got smaller and changed location due to barrel harmonics and not pressure.
If you want more pressure (if possible) add more powder. Have you tweaked the powder charge after you changed the seating depth?

Thanks AZShooter.Still tweaking on degth and powder charge. Seems like when I change one then I have to start all over with the other..How much of the bullet needs to be in the neck and still have some engery left in the bullet? My thought was that the deeper the bullet is in the case then the more time the case has to build pressure before releasing the bullet, and more pressure i was thinking the more FPS . I was going by the bullet touching the lands my groups were about 6 inches higher then it is with the bullet seated in the case a lot more but the groups seem to be tighter. To me if the same bullet and charge is shooting 6 inches higher then it's gonna shoot further but if i don't have consistent groups then not really accomplishing a whole lot. Was just trying to figure out if it was a pressure thing or not because of the bullet touching the lands causing more pressure and that is what is making it shoot so much higher.
Thanx
