Hi all, just a quick question...
I've been given some 145gr collar button boolits for my 45-70 and I'm wondering where exactly it is best to seat them.
Here is a picture of the boolit.

And here is a pic of some that I loaded already.

Now, my question has to do with whether I should be crimping behind the forward band, on it or in front of it. I'm wondering about it because if I crimp behind it, there is really nothing keeping the bullet from leaning because the only other contact point inside the case is a half inch back at the rear. If I crimp on it, I risk distorting/sizing that band and effecting accuracy. If I crimp in front of it, could the bullet get pushed down into the case on rounds loaded in the tube? I saw pic's once of some loaded with both bands completely inside the case.
I've shot just a couple of these and they shot great at 50 yards loaded to the rear of the front band as pictured but I'm just wondering if that is the best setup.
