[QUOTE="redneckclimbing, post: 688162, member: 41124"] So I am developing a round for a friend's 7mm RUM. Worked some loads up at 200 yds. shooting well around 89 and 91 grains of Retumbo 180 Berger HVLD. COAL 3.650. I just did two rounds of each the first time, this time I made four of each .5 grains in each direction of these. I am shooting with a bi-pod on the front and a rear bag. The scope is a 3X9 and has no parallax adjustment. I know this is not ideal but it should not be as bad as it was I don't think. Shot the loads at 400 yds. today to alleviate some of the parallax issue. Was taking my time dry firing between shots to keep myself from flinching. I used two of the 88.5 gr. loads to get on paper at 400 (they were both short) then the next two fell about 1.5" apart at about 10 and 4. The rest of the loads had good vertical spreads ( about 1.5") but would be spread from one end of the paper to the other (about 12"). The wind was blowing full value at about 5-7 and we were watching the mirage pretty close so I expected better. My question is, is the barrel just grouping them like this or am I doing something else really wrong? (aka trigger pull) My next step is to obviously shoot some more 88.5 gr. loads, which I will try to do later this week. But in the mean time any suggestions would be greatly appreciated. [/QUOTE]
