[QUOTE="Pdvdh, post: 216404, member: 4191"] I wouldn't go with full power loads. Others may feel differently. If you're blowing the shoulder forward and outward, I would use a reduced load. If you get any shoulder or neck splitting, you'll have to anneal the cases prior to fireforming. I incurred this problem when fireforming RWS 404 Jeffery brass to the 338 Edge. It wouldn't be a bad idea to anneal the case shoulder/neck prior to fireforming if you're comfortable doing that. That should prevent any case splitting and by the time you've necked down and fireformed the brass, it would be a good idea to anneal it anyhow. I had to get knowledgable and comfortable with annealing since the 404 Jeffery RWS brass was $2.50 a piece at that time (3-4 years ago) and I couldn't afford to keep losing cases due to splits at the shoulder/body junction. You could even fireform with cornmeal at this point since you're headspacing off of the enlarged neck. This would save you some bullets and wear and tear on your barrel. [/QUOTE]
