75gr Amax 100yrd groups & Load data for TIKKA 223.
This was a long project with a lot of range test at both 100 & 200yrds, and the final results of the entire process was range tested today 1 final time with “2” rifles. Some of you have been following the post started from a previous topic outlining my 200yrd range test. Here's the final range test with complete load data. All work started with an 200yrd OCW test that verified an internet load,… then load tested for 200yrd range results,… then 1 load tweaked for both my Lite and Varmint 223 rifles. It shoots equally well in both rifles.
Load Data
Brass – Hornady (trimmed to 1.75″)
Powder – Varget = 25.3grs
Bullet – 75gr Amax
COAL – 2.45″ +/- for your rifle, its will need some fine tuning to be perfect.
Jump to lands – .030″ – .035″10rds over Chronograph (fps) T3 Varmint / The t3 Lite barrel shot 25 – 30 fps slower on average.

2914 2903AVG = 2899.1 fps
SD = 11.31 fps
ES = 35 fpsGun Tested – 223 T3 Lite / Nikon M223 Scope 4-16 x 42mm
Gun Tested – 223 T3 Varmint / Vortex Viper HS LR 6-24 x 50mm2 – 100yrd “Routine Groups”…1/4” MOA average or better is possible.
Yellow circle outlined on both targets is 1/2″ outside diameter…all shots from both rifles are inside 1/2″…
Each target had 2 – 3 shot mags fired from each test gun, for a total of 6 shots at each target from each rifle. The T3 Varmint shot better on average but the T3 Lite was no slouch!
All shots fired from modified T3 factory mag rebuilt to handle the extra COAL needed for the longer bullets…mag mod should handle 80gr Amax & 90gr Bergers as well
