Need Quickload help

I am hoping someone here can run QL for my 280 Rem.

I plan to use RL 23 and/or RL 26, CCI 200, rem brass, Barnes 145 LRX.
My rifle has a 24” barrel.

Thanks in advance for your help.

I think they need case capacity also

Yes, salt works as well as water.
Cartridge OAL and distance from lands would help also...

Email alliant they will give you recommendations for loads with that combo. You need a lot more data for quick load most guys that run it may not want to give out the info for safety reasons.

This is for RL23

Code:

Cartridge          : .280 Rem.

Bullet             : .284, 145, Barnes 'LRX'BT 30282

Useable Case Capaci: 58.029 grain H2O = 3.768 cm³

Cartridge O.A.L. L6: 3.330 inch = 84.58 mm

Barrel Length      : 24.0 inch = 609.6 mm

Powder             : Alliant Reloder-23



Predicted data by increasing and decreasing the given charge,

incremented in steps of 1.0% of nominal charge.

CAUTION: Figures exceed maximum and minimum recommended loads !

Thank you to those that responded. I now have enough data to start safely working up some loads.

Barnes had not tested and did not have plans to try RL23, but they had recipes for RL26 in 270 Win (awfully close to a 280, no?) that were a useful source of starting information...
