I got a new rem 700 in 270wsm. Floated and bedded the barrel in a new HS stock. Been working on load dev for the last month and not really getting to where I want it. I bought 300 pieces of new win brass. Ran them all through an expander ball to evenly open the mouths and then trimmed them all for consistency. When I seat bullets some go in nice and smooth while others have noticeably more resistance leading me to believe that I have a wide range of neck tensions with loaded cases. I’m just working with the new brass now so have no experience resizing these cases and using them for a second firing. I’m not sorting cases or bullets but should be able to get more accuracy than I am currently. I found a few loads that will get me to 1”MOA at 100yds or maybe just under. I seem to be vertically stringing more than horizontally so I was wondering if neck tension could be a factor? I usually use Norma or Lapua cases in all my other sticks and have not noticed this before. Should I see more consistent neck tension when loading these Win cases for the second firing? I don’t neck turn and don’t plan on getting into that. Just wondering if Win cases might be a little lesser quality and be causing some of the accuracy issues I’m finding. My goal would be .75” MOA which I think is definitely attainable with this rifle. Interestingly enough, some of my best groups have come from Nosler Custom Grade factory ammo. Wish I knew or could get my hands on whatever powder they charge those with to give it a try. I’m loading the same bullets in my hand loads… 140gr Accubonds. Any insight would be appreciated. Thank you.
