[QUOTE="BLC3128, post: 1664381, member: 101837"] Just an update. I did make some serious changes with my reloading techniques and tools. I upgraded my dies for the 7 WBY to a Redding bushing neck die. I size the neck down .002” and then body size /bump shoulder back .002” as well. Cases were all trimmed and weight sorted.. I have have enough N570 for the life of my other magnums that use it. So i decided to give it a try and also decided to give the 160gr accubond ONE LAST TRY! I seated the bullet out to max max length and loaded up 76gr, 77gr, 78gr .... all the way up to 81gr. At 81gr it is very slightly compressed.. Upon my results this morning I am very pleased. All of the charge weights shot under 1” @100 yards. A few were just under .75” with 77gr being .294” @100. With that being said I pay more attention to ES and SD during my charge weight testing. I did not hit pressure , but I believe to have found a higher node at 81gr. The group was .734” @100. AVG Velocity was 3180 , ES was 19 and SD was 10. No pressure whatsoever! Anyways going forwards, I intended to shoot charge weights of 80.4, 80.7, 81, 81.3, 81.7 , take the best from there and then proceed to adjust seating depths and test them at 300 yards. Moral of the story is - I became much more consistent in my brass prep and I believe that was the underlying issue ! Results to come in the next week or so. [/QUOTE]
