I am about to finnish my 284 barrel I need some geed starting points for the 284 with the 180 hybreds,powder and how much jump or jam any help would be geed
 
Most all the guys I shoot with and I are using 55.3-55.6 gr of H4831sc jumped .020-.030 with CCI BR2 primers.
 
52.5 grains of RL17, bullet off lands .050 works well in my rifle. My SD & ES are single digits. The rifle is very accurate.

Im running my 180s with 51-52 gr of RL 17 .005 off...getting 2925-2935 fps out of my 30 inch bartlein.
 
I am shooting the 180 hybrids with 51.2 grains RL17 and 32 thousandths jump. Getting 2825 out of my 26 inch barrel.
 
Start with a .010 jump. It should shoot somewhere between 50.8 and 51.5 depending on the barrel. At least that is what I found with my lot of H4350


Look for 2820 to 2850 fps it should shoot in that range.
