Loading test rounds for my 6.5-284 with H4350, Lapua brass, and two bullets: 124 grain Hammer Hunters and 147 grain ELD-M. I shot last weekend up to 49.0gr with both bullets and no pressure. Great groups but am going again this weekend to try more- what puzzles me is the lack of case fill. I can shake the rounds and hear the powder pretty loose in there. Should I be worried? I don’t want to cram 55gr of powder in there to fill the case, but I don’t want too little fill either to prevent the powder from burning funky on ignition. 49 grains is already over both Nosler and Hornady book max. Am I worried about nothing? Using a long action Rem700. Chamber base to ogive is 2.547” for the 147 and 2.530” for the 124. I came back about .015” from that for each bullet which put my COAL for the 147 at about 3.135” and the 124 at 3.058”. Should I be going shorter to eliminate the shakes? I built on a long action to seat further out... I have not chronographed yet...I want to find my most accurate load first as I use a magnetospeed and it attaches to the barrel. Thanks in advance!
