[QUOTE="Rich Coyle, post: 1335412, member: 70559"] A photo would be nice, but there is no "paper clip" on either my desk top computer or my daughter's lap top. So I will try to describe the results accurately. I loaded ten Hornady brass with Winchester WLRM primers because I have more of them than anything else. I started with 40.0 grains of Ramshot Hunter and increased each one with .5 grains more. Then a Nosler Accubond 140 was loaded .030" from the lands. I got that amount from Nosler. I fired the ladder at 200 yards. The "wind" was a very light breeze varying from nothing to maybe 1MPH. During the 1 1/2 hour shooting session the temperature went from 68* to 71*. I fired two shots and let the barrel cool. First bullet hit about 8" low and 2" left of point of aim. Number two hit about 1/2" higher and directly under point of aim. Number 3 overlapped #2 on its top. Numbers 4,5,6 made a horizontal line 7/8" long 2"above #3. Numbers 7 & 8 were another 2" above them horizontally and about 1/2" apart. Number 9 was 1/2" above them 7/8" to the right. Number 10 was 5/8" above # 7. Numbers 7,8,9,10 made a "group" of 1 3/8". There are three obvious nodes. The velocity smoothly increased from 2,502 feet per second to 2,754 feet per second. After firing this I talked to Ramshot. According to tech the load can be increased 1 grain more. On Monday I will load 45.0, 45.5 and 46.0 on the same target. [/QUOTE]
