[QUOTE="remingtonman_25_06, post: 33494, member: 1403"] I got a chance to test out some new loads for my .300 RUM. It is a Rem 700 LSS. Complete factory except trigger down to 2 3/4 lbs. I tested the 220g SMK and H-1000. The first load I tested a while back was 82.4g of H-1000, Fed 215, 3.66" and the others were at 3.670". The 3.66" load shot 1 inch with all 3 shots being evenly placed horizontally. The 3.670" put 2 shots touching and the 3rd a flyer 1 inch low. They were chronographing at 2785fps. After doing more research and asking some questions, I found a new starting point. I went up to 88g of H-1000 since several people were going up to 92.5 and 92 grains, I felt 88g was a good place to start. I also made a switch in primers to see if they would make any difference. I used CCI BR-2 primers. Loads go as follows 88g H-1000 First 2 shots were **** near 1 CCI BR-2 hole. The 3rd was the 3051fps 3.75" and it was a flyer at 1 inch 3020fps high and 1 inch left. 3021fps 3051fps 90g H-1000 It was a 2 inch group in the CCI BR-2 form of a triangle. It just 3.75" didn't shoot. 3098fps 3092fps 3113fps 91g H-1000 First 2 shots were **** near CCI BR-2 touching. 3rd shot was a big 3.725" flyer at 1.5 inches low and 2 3075fps inches left. 3072fps 3065fps 92g H-1000 1st and 3rd shot were 1/2 inch CCI BR-2 2nd shot was a flyer at 1 inch 3.735" low and 2 inches right. 3109fps 3101fps 3098fps That was all that I tested. I dont really know what load to use. The difference in fps between 88g and 92g is only about 75fps. They all seem to be somewhat consistent. The 91g load had a spread of 10fps. The 92g load had a spread of 11fps. The other 2 had 2 shots real close and consistent, group wise also, but the 88g and 90g load each had the 1 bad one in the group for velocity. I think what I will do is work with the 88g load as 3025fps for the 220g SMK is plenty fast for my 26" barrel. I will work with seating depth A LOT.
