[QUOTE="LongBomber, post: 2655893, member: 14435"] I have changed a bit in the last 2 years. Now I pick a bullet/powder combo I would expect to work in the cartridge, grab lapua alpha or adg brass and: 1. Find the lands with the Alex Wheeler method, and run a seating depth test with 3 shot groups at 100y. I used to start close to the lands but now I start at 40thou off and go further in 3 thou steps out to 61 or 64thou off. Taking the widest node in seating depth to the next steps. If the bullet won’t give 1/2moa accuracy with just seating depth tuning I swap to a different bullet. I found if it wont shoot well at 100y with just seating depth tuning its likely going to be a pain to get the load in tune and keep it in tune. 2. Size the brass from #1 to bump shoulders 2 thou max, the brass is now formed to this chamber. 3. Run powder charge ladder in .2gr steps at the seating depth from step 1. Usually I start with a mid book load and go up till I hit pressure. Shot on paper at 600 and past the labradar. Pick the widest node thats close to the speed I would expect from the cartridge. 4. Load 5 at .2 gr steps inside the node to see what 300 or 600y groups look like. Pick the best from there. 5. Then just because I enjoy shooting I will load up a bunch and do a few 10 shot groups at 1000y. Normally that takes me 21-24 shots for step 1, 12-15 shots for step 3 and 15 for step 4. At that point usually I get a load that shoots consistent small groups. [/QUOTE]
