Testing the 136 scenar with varget went great the first 100 NEW lapua brass loads, then full length sized them and hmmm got some pressure signs and a pierced primer with the exact same powder charges, bullet, seating depth and primer. The only difference was a different lot of primers (still cci 450 though) and using a 287 neck bushing to resize them(loaded round measures 289 to 290) . The headspace checks out with go and no go , the overall chamber length for the brass checks out , It is a Criterion barrel with a no turn neck n a Savage action. Redding type S bushing dies were used. Charge weight was varget 36.8 and 37.0, I checked the weight on two different scales and even pulled the bullet on a loaded round to make sure the weight was correct. What am I missing other than its just to hot?? Why did the new brass do fine?? thanks for any replys
