[QUOTE="jweigel, post: 1216831, member: 72021"] Good points guys....I did have a great load with Retumbo and the 180 VLD in this STW that ran 3015 and .5 MOA. I held less them 1 MOA out past 1000 yrds. I also have a 7RM Sendero. After testing lots of powder I settle on 7828SC pushing a 168VLD 3050 but around 1 MOA. This winter I picked up some N570 and started testing it in the RM first. But jumped to the 180VLDs. I was able to get to 3010 but started getting extractor marks but groups for a spread of 2 grains of powder were all less then .5 MOA. Backed off 1.5 grains and settled on 2950 and still .5 MOA. Have shot it several times now cold bore....even squeaky clean and the first three shots are still .5MOA. Bingo! Started playing with these 195s in the STW using N570. After doing seating depth and then pressure testing I never really had groups below 1MOA and quit. Using the same seating depth for the 180s/Retumbo load I did pressure workup with N570. Could get to 3200 before signs of pressure but groups opened up after 3100 so I settled on 80 grains...well below pressure and a .75 MOA. So now i have one gun shooting 180s at 2950 and the other at 3100. Kind of boring and seems like I not getting the full potential of the STW. Back to the 195s....that is where I am at now. I just visited with Dan with Chinchaga bullets about his 196 VLD. I'm thinking I should just order a box rather then keep burning powder on these 195s. I will still load up some a shoot out around 500 yards but expectations as pointed out are it will be the same 1 moa or worse as it is at 200. That's my story and I'm sticking to it. jjw ND [/QUOTE]
