I have developed a load for my 300 RUM. The load consists of 180gr Barnes TSX, 92 grains of RL-25 and Fed 215 primers. The chronographed velocity runs from 3289 to 3311. One hundred yd accuracy is sub 1 inch groups, however at 500 hundred meters (550 yds), I range between 6 and 9 inch groups. This is my first long range gun, and attempt at long range accuracy. Are these groups considered fair, good or very good? I feel that these are acceptable for hunting, however shots at this distance while hunting, will not be from a bench rest. Any input would be appreciated. gjszabo Adversity is inevitable, Stress is optional!
