Using R22 64 grains and 140 grain BT in Nosler brass and WLR primer at 3390 from 26" tube. Hart Barrel
Interesting...a 280AI juggernauting 140's at STW and Mashburn velocities;and from the same length barrel that Nosler says gives,at best,100 fps less velocity.
And people wonder why I think 280AI users are the biggest wishful thinkers on the planet,and greatest purveyors of dis-informatiion.
Any fool can keep adding a double based propellant like R22 until the chronograph screams,just to make a cartridge look good.
That's as humerous as quoting Quick Loads as evidence of pressure in your rifle....another joke of the uninitiated.
