I decided to go with a Lee factory crimp die. According to their website trim length isn't a factor in it's operation and after having seen the illustrations on their website I understand why.
I know many people don't crimp with a single shot but I'm just not comfortable with that. I like a good crimp.
I also eard back from staff ballistician Johan Loubser at Acurate powders. Acording to him, .070" shorter isn't enough to affect the recommended powder charges using 5744. Probably because the case is so massive and it's a relatively low pressure powder.
So I'll be good to go as soon as I get my gun back.
Thanks for all the replies everyone.
