I've tried lots of powder and my local smithy turned me on to the reloader19 and I've had several freinds try it and loved the groups they had with it!
I started reloading last winter.I have RL19.RL22,IMR 4350,and IMR 4398.I'll bw working up loads with all these using 140,150gr bullets for both the .280 and 7x57.Thanks for the load advice!
