I've been working up a load on my 22-243 AI with 90 gr Berger VLDs, and got it shooting good enough for me. The group below is the first 6 shots fired at 296 yds. The wild one is 1 1/2" high, but the other 5 are at a dime. I want to keep shooting this load...BUT... I just found out that the Ogives and Bullet Lengths are different in each box of bullets. Most of the boxes are close with each other, but the bullets I used in working up this load are shorter and fatter than the rest of the boxes... so what do I do now. Here is what I have.....
Ogive to base measures... .703 total bullet length is....1.225 (my workup length)
Most of the bullets in the other boxes average a ogive measurement of...
660-670....with total length = 1.265-70
AND>>>> AND>>>>> When I seated a .703 bullet and a .670 bullet with the same seating depth measurement as I was before... the 703 bullet had a total length of 2.782.... and the .670 measured a total of 2.831.
Man O Man.... that's a .49 spread difference.
So what do I do now.... start my workup all over again with the .670 bullets... since I've only got a few more of the .703...?
I'm hoping you guys have a better answer than starting all over again.... thanks....Dan
