Hello everyone,
I'm a reasonably new shooter from the NW suburbs of Chicago. I purchased a 6.5 APO Savage 10 6.5 Creedmoor last summer and started reloading this Spring. My first reloads were with IMR 4350 and StaBall 6.5 using Hornady 140 gr ELD-Match bullets. After a whole batch with a COAL of 2.800" like the factory ammo, I started playing with the seating depth. Following Eric Cortina's advice, I measured the lands at 2.847", subtracted 0.020" (2.827") and then down in 0.003" increments. I love the RCBS MatchMaster seater die for those precision adjustments.
With the 24" barrel, my muzzle velocities seem to be higher than the H4350 published values in the reloading guides. (measured with a MagnetoSpeed V3)
Most of my shooting has been 5-shot groups at 100 yards, with a few rounds at the range's 200 yard max near the end of the day. My next range trip will include far more rounds at 200 yards since I've found a sweet spot of powder and seating depth.
I've been following several long distance rifle and reloading YouTube channels including Eric Cortina, Ultimate Reloader, Backfire and GunBlue490.

- IMR 4350 did really well with 41.1 grains and a COAL of 2.824".
- I recently found a few pounds of Hodgdon 4350 online. My rifle seems to really like either 40.5 or 41.0 gr of that and a COAL of 2.821".
With the 24" barrel, my muzzle velocities seem to be higher than the H4350 published values in the reloading guides. (measured with a MagnetoSpeed V3)
40.5 grains: Ave = 2749 ft/sec; Max = 2776, Min=2727, SD=13.8
41.0 grains: Ave = 2770 ft/sec; Max = 2792, Min=2744, SD=14.5
