Reloader 19 Powder in .300 RUM????

R-19 is ok with the lighter bullets. I used 87.0gr behind a 150gr Mk. It shot .75 to 1.25in groups. I found R22 to shoot better.

R19
150 to 155gr bullets: 82.0 TO 91.0
165 to 168gr bullets: 80.0 to 89.0
 
I use reloader 22 in my 300rum and found that 95.0gr powder and a 150gr barns xbullet shoot half inch groups at 100yard. /ubbthreads/images/graemlins/smile.gif
