[QUOTE="Mram10us, post: 1796655, member: 111667"] Took it out again today. A couple findings. 1. hornady brass separates easily while fireforming. Bertram, nosler and norma were fine 2. With the flat, every load charge felt a bit tight on extraction compared to normal. 3. R33 charge only got to 98 before feeling a bit tight on extraction and left pressure marks 4. 97gr r33 with 230 otm looks to be incredible for accuracy and on a node. No chrono 5. 85.7gr h1000 shot well also. 6. Reduced loads with 27gr trail boss and a 165 seem a bit hot for fireforming. I'll try 25gr next time. More to come. [/QUOTE]
