Thread: Incipient head seperation and a possible mitigation method.

Yes, i've of that Larry Willis die and gave it some thought. My rifle is 308 Norma mag from 1960s era and the only brass is from Norma. Howevet, I figured I may ad well try a low cost solution as an experiment. The rifle shoots sub moa so well worth looking at extending case life. Thanks for yr input though.

Greetings @Woody,
Have not heard of the .308 Norma Mag for a while. Some time ago my friend had developed a burning desire for a .300 H&H but could not find anyone with a reamer but found someone with a .308 Norma Mag one. He had a Parker Hale magnum action and had scrounged up an old .308 target barrel so the Norma would need to be it. He also scrounged up some cases which unfortunately would not chamber even after FL sizing. The tight spot as you will likely know was right in front of the belt. Bugger. This was in the days when bulge buster kits were not available so after a bit of head scratching a stripped .300 Win Mag die was tried. This was better but not much so the next step was to size the case with the case on top of the shell holder which allowed it to enter the die just that little bit more. The cases needed to be tapped out of the die with a rod but it worked a treat.
Regards Grandpamac.

maybe you should neck size only less stress on brass i run pmc brass in 7RM havent had any brass issues so far
