Hi all,
Back in March I posted some questions about a possible new wild cat cartridge and the project is moving along,behind schedule unfortunately) for the rifle I am planning to take to Africa next month for plains game. It's based on a 300 WSM case, necked down to 6.5mm and shortened to an overall case length of 1.825 while maintaining the 35 degree shoulder and the standard body taper.
First I should say that the only wildcat case forming experience I have is making a case larger by fire forming with inert filler to get less body taper & a steeper shoulder angle, and not shortening a case body like I need to do on this one.
I got the forming die,a single die) from the smith tonight.
Here's the problem; I went to start forming cases tonight and lo and behold, when I try to push the shoulder back the necessary .300", it just collapses the case body about and 1/8 of an inch farther down the body like a pop can. The shoulder just seems to not want to budge! What am I doing wrong?
Any suggestions would be much appreciated. I looked through Designing and Forming Custom Cartridges,Ken Howell) as well as Wildcat Cartridges 1 and 2 tonight, but can't figure it out. I only have a matter of weeks left and am desperate to get this setup working if at all possible in time! I've attached the reamer specs and a case comparison in case it helps illustrate what I'm trying to accomplish. Thanks for any help!
