[QUOTE="aghunter, post: 2143068, member: 117433"] Ok guys thanks for the all the comments. Sorry for being MIA but wanted to catch this post up. A couple comments alluded to chasing the lands which I hadn't previously done. I thought I'd measure to touch again to compare to my base line. I use the wheeler method and as I started measuring I noticed I could "feel the lands" much shorter than previously measured. But wait this should be impossible right? Back to basics as something was obviously not right. After some verifying, my sized brass length was at 2.616. This is under the sammi max of 2.620 but over the trim length. I thought this was ok but found it was tight in my chamber and only noticeable on a seated case with the firing pin removed. After trimming brass back to 2.605 I could now properly measure that the lands had grown .012". I took my standard load without making it longer back to the range and shot two 4 shot groups at roughly .7" (didn't pull the target). This tiny bit of length appears to be the root of my problem. I had planed to head back to the range and verify one more time Saturday morning before updating you all but woke up with no taste or smell. You guessed it, I am now sitting at home Covid positive and had to forfiet my hunt. What a couple a weeks! Thanks again to all who commented to help me work through my issue. [/QUOTE]
