[QUOTE="PatriotHenry, post: 2440799, member: 114356"] 1. Pick one HS of brass and stay with it. If you don't you are setting yourself up for failure. Better yet buy 100 pieces of ADG, Petersen, or go to GUNWERKS website. They have once fired (not sure make but you can get enough of one HS) for sale sometimes. 2. What twist is your barrel? If it is slower than 1-8.75 you will have issues with stability. You may have better luck with the 180 pills. See Berger's twist rate calculator :[URL]https://bergerbullets.com/twist-rate-calculator/[/URL] Pick the bullet from the drop down, use your estimated velocity and plug in your twist and elevation you will be shooting at. If I were to build any big 7 I would twist it 1-8 personally. 3. Magnum primers. 4. You will have the best luck with H1000, Retumbo, IMR 7828ssc, & Magpro. H4350 is way too fast, Viht N560 probably too fast for those projo weights. My 2 cents. PH [/QUOTE]
