Thread: 223 on deer

Im using the 52gr targex and the 55gr hornady 2266 (boat tail soft point with cannelure)

For the hornady i use G1BC .235
For the targex i use G1BC .220

Has anyone extensively tested these for the accurate BC? The targex id like to get dialed in enough to take bunnies out to 600 yards (in my 22 250AI not 223) and the Hornady is just a general allround bullet in all my 223s but i feel the Hornady BC is more in the .205 area from what im getting

Velocity is being measured with magneto speed so pretty accurate

Use the Hornady 4DOF app with the drag data for Hornady bullets, rather than try fudge BC. BC is never "right".

There is so much noise in the system - are all inputs correct? Before trying to 'true' BC

- actually zeroed, with a large enough group for confidence
- velocity measured over a large enough sample size of shots to be meaningful
- scope height over bore actually correct
- environmentals?
- scope clicks

Etc


Edit: hmm the 4dof app only lists more recent and LR focused bullets so it's out of the question

.235 G1 is about right for the 55gr flat base soft point. The boat tail may be marginally better. I have shot the flat base ones on game and targets out to 500m with repeatability, with muzzle velocities between 28-2900 fps.

The Hornady 55gr FMJ-BT has a listed G1 of .243 on Strelok. There is nothing in there for either the 55 or 62gr BTSP. I don't think these are commercially sold components by Hornday. I think what we have are over runs from factory components.

30 wallaby and 2 upside Fallow. A good day for the .223.

It’s a Fallow coloured Fallow lying Fallow in a Fallow

Good shooting guys.

Great shooting. I bet you're having a ton of fun. Enjoying the shrt video clips, thanks.

with luck you will be getting this nice damp misty rain today..should make things a bit more pleasant instead of bone dry.. the animals will be out enjoying it.

You have probably covered this before so apologies if so - whats your rifle set up - certainly does the business!

Posted in the stags 2024 thread but here too for record. 4pt shot at 296m required a track and finishing shot due toa ballsup at my end, 8pt shot at 402m. Both using 80gr ELDM, 2720fps.

Great Photo!

Well it's not 223 it was it's older little brother the trebly. The smaller one104lb was bailed,no fuss headshot.the bigger 150lb fella was on run at fifty? Yards with dogs behind and copped a 52grn Speer in boiler room.stayed on feet for maybe twenty seconds then got all wobbly n died

Nice, now where did I put that apple sauce

Interesting the difference between these 2 projectiles. On the left, 80gr eldm, on the right, 73gr eldm. Both recovered from sika at ranges around 300m. These results have been repeatable. It's interesting that the 73gr is much more prone to disintegration but the 80gr so far, have much higher weight retention.
