would someone be kind enough to run a QL for a 280 rem ruger hawkeyre 22" barrel? If possible run it at or near the 270 win pressures. Bullets I currently have are 140 Partition, 140 BT and 160 Accubonds. Powders will be R26, Magpro, or R19, maybe R22. thanks in advance.

Randy
 


Not near QL but here is my data for a Federal 140 Tipped Bear Claw and RL26 out of a Ruger Hawkeye.
 
that's sweet! thanks Scotty-This will be my elk rifle and back up deer gun.
 
Heres what I have when I asked for QL on the 280 at 270 pressures with a 24" tube. Hope it helps!

thanks again! R17 looks pretty good as well, I do have a bunch of it. I've loved it in the 260 and 7-08.
 
Ya RL17 looks really good with the 140s and 150s...I use it in my wife's 7/08 with 150g NBTs at 2825fps. Only rifle I've ever used it in. I'm going to concentrate around RL26/RL22/IMR7828 in my 280.

or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !
