Rabbit,

I'm back after some technical difficuties! Thank you, David.
Like I said, I use a 2.5" hull because my 75 gr. bp, .125 card,.5 fiber wad, 1 oz. shot and .7 overshot load fit great in that length of hull. I will run into minor fitting when dealing with differant interior base wads. Remington offer the most challenge.

I have cut down 2 3/4" hulls to some success but prefer 3" or longer hulls.
Hulls I have tried are:

Win Universal and super speed. Super speeds are better because of the 6 point crimp, both don't roll crimp very well. They will work and you can find them by the bucket full at my public traprange.

Federal Game load are the same deal.

I love the Federal Premium loads, Win Supremes and Drylock and Experts. Remington can be a chanllenge though as they tend to customize each load they do. Old Rem mohawks are differant than nitro steel ect. I make it a point to look for hulls every time I'm out. I keep bags of Win,Rem and Fed separted and ready for loading.
Since I reprime on a Mec 650 I am considering a super sizer and possible even running my completed shells through the sizer die of my press.

Good Luck and have fun! I thing you will find this is addicting!
