New blocks

[Kurt]

That 1.350 should be a very good length for th 1/19 twist with that ogive it has.
I set my adjustable mould at 1.356.
That .433 prolate I have is 1.460 long and so is the elliptical from KAL and they both get squirly past 600 but they should work very good in the 1/17 twist I'm building.
If Ricks mould blocks had the pin placement where I could turn the blocks down and have a meplat like yours it would be the same length.
If that bullet does not work in the 77 let me know. I can push it a little faster in my 90..
