[QUOTE="Mikecr, post: 738810, member: 1521"] This is mostly what I've messed with over the years; *223- Cooper (1/4moa) 223- Browning 300wsm- Savage *6br- Browning rebarrel (3/8moa) 6dasher-Savage rebarrel 6XC- Tubb2000 (McMillan) *6.5wssm- BAT IBS LG (3/8moa) 6.53Scramjet- Savage (Lazzeroni) *what I currently hold Bart I have no problem holding headspace, fired or otherwise, to 1.5thou. MINE doesn't change on primer firing. Boomtube I have no problem holding desired seating depth to lands under 1thou tolerance. This, because I qualify bullet ogive radius, use only Wilson inline seating, and my neck tensions are measured & matched. Also, my primers are set to the same depth at exactly the desired crush. Man, I must be a miracle worker... To me it seems ridiculous to generalize that these things can't be controlled. They can be, and when they are, it can payoff. If I were to let slip the seating for my Cooper by 6thou either way, grouping would immediately double in size. Fortunately, I could not possibly be off by so much as 1thou & not catch it through measure. [/QUOTE]
