Im working on improving my shooting ability for hunting. Ive set 2 identical tikkas - 18” .223 & 6.5cm, SWFA, assembled correctly.

I’ve made a lot of progress with positional shooting and “the hunting rifle drill”

I’ve read and mostly understand quick drop and wind brackets. Time to test it out & practice. How do you match training ammo to your guns so these concepts apply? Is it just chrono each round through your short barrel and use G1 bc to apply corrections? Or is there a better method before buying a bunch of different boxes?

Looking at the ballistic chart, my cheap 223 ammo seems way off. Is that just the nature of a lightweight short bullet doesn’t match the profile of more efficient ones? Trying to keep this as simple as possible across my two rifles and training and hunting ammo!
 
Try playing with the zero range on your .223. Mine’s too slow with 77tmk’s but if I zero at 150-ish it gets close to QD from 300-500.
 
Federal has a ballistic calculator you can run online to run all scenarios pretty quick to adjust zero distance to see where each for line up for qd the furthest and then keep adjusting wind value to see what speed it is where it lines up. My 223 with 73’s at 2730 lines up to qd within .1 to 600 at my elevation with 150 zero and is a 6 kmh wind gun or just under 4 mph, my 308 with 168’s at 2592 lines up to 600 with a 170 zero and is an 8 kmh (5mph)....you get pretty handy and fast running calculator, helps see what you have and also for future planning what you want
