Thank you!
I had no data to go on so figured I'd back off my old R22 loads a bit, and started with 58gr. My chrony said 2960fps. I backed off to 57grs. I got a nice .446" group. No pressure signs either time. I didn't take my chrony to range with 57gr load, but used another one belonging...
I'm having difficulty finding R23 data for the .280 Rem.
I'm working on loads and would be very appreciative if someone could help out with a QL run for:
.280 Rem
160 Nos. Accubond
Reloader 23
24" bbl
Remington Brass
Fed 210M Primers
OAL 3.330
Thanks in advance,
Jim
