New-to-me rifle, bought 100 rounds of factory Hornady 40gr Vmax (3800fps) to sight in the scope and see how it did.
Prepped some brass last night & loaded 20rds this morning based off "intuition" from Hodgdon & Lee data for 69gr Sierra BTHP, as they have none for this (68gr BTHP .224) bullet.
- Savage 16 FLHSS .223 Rem converted to factory DBM (by me)
- Sightron 6-24x50mm LRMD/CM
- Vortex Med Standard rings
- flat Weaver rail
Hornady .224" 68gr BTHP Match
Hornady fire-formed brass @ 1.750"
CCI #450 Sm Mag Rifle primers
Hodgdon Varget @ 24.0 / 24.5 / 25.0 / 25.5 grains
COAL @ 2.300" +/- 0.001"
All 5-shot groups @ 50m (5000ft elevation, ~ 10deg C) shot off a Herters folding bench (no bipod), I didn't want to move all my stuff back to 100m after I confirmed I was on paper.
Velocities were approx. 2870/2930/2990/3030 FPS, respectively. I had issues recording data from the chronograph to my phone, but I had pen/paper though.
No signs of pressure at any powder charge...
Going to load another 20 rounds @ 24.5 / 24.75 / 25.0 grains and see how it goes. Or should I just go with 24.5 grains ?
The top 2 groups on that target are 5 shots each... Bottom left group is 25.5 grains.
I'm pretty :)
