Drop estimates please

Hello,
I don't have a chrono...probably can't afford one soon...and the load I found is warmer than in the Berger manual...looking for 300yard and 600yard guesstimates from those with similar rifles...if you're using rightsights drops on that appreciated...
26" barreled space gun 223wylde chamber
80 grain Berger
23.2 and 23.5 grains of RL-15
BR-4's
LC brass

Groups attached at 100 yards.
Thanks,
Ken

using the same settings, ammo, fire groups at 200/300 to see the change in the point of impact then we can work backwards and get you close.

Not always able to get out to the range with 200-300 or 600 yard ranges...figured I'd ask here since I bet there are people with similar set ups...
Forgot to mention the gas tube is the 2" longer extended gas tube.
Thanks,
Ken

+ 1 Min. @ 200 yds. and +3 min. @ 300 yds. should be pretty close.

At 600 yds. you will need approx. 11 minutes over your 100 yd setting
