Load and BC Question

[Still-n-Quiet]

Ok, here's the deal: I don't have a chronograph and I'd like not to shoot 15 more shots to find out.

Here's what I'm shooting:

CVA Optima
300gr SST
100gr triple 7 pellets

It is zeroed at 80 yards. My general question is what do y'all shooting the same loads get for drops at, say, 100 or 150 yards?

Of course this is a guess, you still need to verify in the field:

Zero @ 80 with a 300 sst (b.c.=.240) with 100g 777 (velocity = 1600fps):

Range Drop(inches), Drop (MOA)
0 -1.5 , ***
25 0.0 , 0.1
50 0.6 , 1.2
75 0.2 , 0.3
100 -1.3 , -1.2
125 -4.0 , -3.0
150 -7.9 , -5.0
175 -13.2 , -7.2
200 -20.1 , -9.6
225 -28.5 , -12.1
250 -38.6 , -14.7
275 -50.5 , -17.5
300 -64.3 , -20.5
