[QUOTE="chesspunker, post: 1464028, member: 106356"] I want to thank you all very much for your help! I shot my first 145 GR LRX sub MOA three shot group yesterday with my 7 mm WBY (see attached). I used 73.1 Grains of H4831SC Powder. Shooting conditions weren't the best because there was a 16 - 18 MPH West wind, which pretty much blows right at the shooter (not really a cross wind). I used my Caldwell The Rock front rest and my Protektor rabbit ear rear bag. My first cartridge length was 2.796" to ogive and I wasn't happy at all. It was another 2" group. I started with a barrel that had been fouled with 7 shots and my gun has always liked being clean. I decided to clean the barrel before my next group because I had a feeling the dirty barrel might have contributed to the bad group. My next cartridge length was at 2.776" to ogive. I started with one fouling shot at a different lower target and then shot a 3 shot group. That group tightened up to around 1.25" and I felt like I was making progress. The good news is that if I used my fouling shot as part of the group it would have still been 1.25". My next cartridge length was at 2.756" to ogive and this produced my first sub MOA group which is shown in the photo. I cleaned my gun again after the previous group. My fouling shot was at the same lower target as the previous fouling shot and it touched the same hole! I then proceeded to shoot three more shots and they measured about 0.875" (shown in photo). If I included my fouling shot in this group it also would have remained sub MOA. I cleaned my gun again and I shot one more group with a cartridge length of 2.736" to ogive. The problem is that I wasn't banking on such a short length being a good bet and I only brought three bullets at that length. My fouling shot was about 1.0" away from my previous two fouling shots. The two bullets I had left went through the same hole. On my next trip to the range I'm bringing 15 cartridges. I'm testing the following lengths 2.756" (my winner from last time), 2.746" (new size), and 2.736" to ogive. I will start with a clean barrel before shooting each group. I'll shoot my fouling shot at a lower target and then the four shot group at a target above the fouling shot target. Hopefully I can repeat my good results and then load up 100 rounds and finally be able to sleep at night! LOL. [/QUOTE]
