Satterlee 10 Round Load Development

[Lemonaid]

Bullet drop from two tested loads, one good ES the other not so good, using the Hornady Ballistic Calculator and the high and low velocity.
Monster 20 barrel. I knew SD and ES were important but this made me reevaluate what I need for long range.

load one is Speer 140 Hot core, 27.0 grains of Win 748, cci 450, Hornady case 5 shot group at 100=.838 ES=57

---------------------------300 yards----------------600 yards--------------1000 yards
2178---------------------23-------------------------141.7-------------------534.8
2235---------------------21.6-----------------------133.7-------------------505.2
----------------------------------------------------------------------------------------
---------------------------1.4-------------------------8-------------------------29.6

Load number 2 Sierra 120MK, RL15 29.3, cci 450 Hornady case 5 round group at 100 = 1.290 ES=18
2497---------------------17.8-----------------------111.9-------------------446.3
