I am really in a quandry. i started reloading for my new Weatherby Howa 1500 in 204 Ruger. I bought brand new winchester brass when i got the rifle. never fired factory loads in her. I run all of this brass thru a full size die, RCBS new, and trim to 1.840 and chamfer inside and out. Then the problem arises when i begin to seat the bullets. after about 15 or 20 rounds, sometimes less, i start getting crushed cases. the cases crush on the shoulder edge, and with very little force on the press handle. i have double and triple checked the seating die setup. Rcbs says back the die off, then run a powder charged shell up in the die, then run the die down until it touches the mouth, then back the die off one full turn, which i did and locked it down. then set the seating depth at 2.256. i am loading h335 powder with hornady 40gr vmax bullets. i even backed the die off 2 full turns with no difference. i have checked the inside neck diameter with my caliper at .201 to .203 and even started checking the bullet diameter at .204. i have since bought a set of redding dies, and no difference, and even a set of rcbs competition dies. same problem. with the competition dies it is very hard to set up too close the bottom of the die. i am not new to reloading. been reloading 223's by the hundreds with little or no problems. i load for my 270 with no problems and have been loading for my 357 revolver. 357 and a whole lot of 38's. i even tried loading 32gr vmax with no difference. i have not tried loading any of my 1x fired brass, but that will be my next step. this is gettin expensive with wasted brass, powder primers and bullets.
has anyone else had any problems with winchester new brass. i bought 600 rounds of this stuff, and have loaded 140 plus another 30 to 40 crushed cases.
any ideas will be truly appreciated.
