Seems like everything I read about the correct blow length for Dasher cases is around the 1.553 length.
I can only get between 1.544 / 1.546...
I started with to low of a load and got 1.532 and worked my way up to where I getting the 1.544 /1.546 area with anywhere
between 32 gr and 33 gr of varget (32 gr made the same blow length as 33 gr)
I'm using the expanded neck (.257) necked down to a CRUNCH fit and heavy neck pressure (.267 loaded round, .263 bushing).
I'm sure the case isn't moving with the crunch fit, bullet in the lands 20-25 thousands.
I've tried Rem 7 1/2, CCI 450's, and 205 Fed's with the only diff being gratered Fed primers @ 32.5+ load);
Any idea why I'm getting what seems to be a "short" blow length.
Maybe it is just the way my chamber is but thought I'd see if anyone else has had this "problem".
It might not even be a problem as I haven't tried to work up a load yet, Just fire forming now but don't want to have a bunch of wasted cases from being to short of a blow.......
