[QUOTE="remingtonman_25_06, post: 227718, member: 1403"] The following loads were all very accurate to 800 and 1150 yards from my Rem 700 LSS 300 RUM. Only thing done to it was trigger job. 92-94g of H1000 with 200g AB or SMK's was 3/4MOA or better out to 800 yards. 88g H1000 with 210g VLD's was also 3/4 MOA 89g H1000 with 220g SMK was also 3/4 MOA Triggers good, good scope, good rests. I think you just need to work on finding a new load. Try a couple different powders. Most 300 RUMs love H1000 or Retumbo. Load the bullets to the max length of your magazine. In my Rem LSS it was something like 3.660" for the AB's and I loaded the SMK's and VLD's to the lands but used it as a single shot. Forget about doing 5 shot groups for a factory sporter contour hunting rifle like the 300 RUM. 3 shots is good enough. How many times do you get an animal to stand around for more then 3 shots??? Hope it works out for you. The 300 RUM is capable of very very good accuracy. My personal bests were 1.5" at 525, 3.5" at 800, and about 60-70% hit ratio on a 15" steel plate at 1150. [/QUOTE]
