Need a little help. I took my old Remington 700 and had Hart install a new barrel chambered for 25-06 SAMI.
Bought a Wilson neck sizing die for factory brass.
Bought a gismo from Hornady to put on my dial caliper to measure head to Datum.
Fired brass is right on the money as far as the head to Datum length.
The problem:
After 10 firings the brass is tight going into the chamber.
Bring out the trusty RCBS full length resizing dies.
Size the trimmed to length brass and the head to Datum length lengthens.
Extremely difficult to chamber.
Went to a Texan shell holder which is about .200" less in height no change
still very tight into the chamber.
Sent dies to RCBS. They declare the dies are perfect.
They suggest lowering the die 1/8 to 1/4 turn past touching the shellholder.
Since I have come down an extra .200" and the case is not flowing up into the sizing die I think the brass case is too hard and needs annealing or needs to be pitched.
Any comments would be appreciated.
