I got out some loads in 300 Weatherby that I assembled in 2016 to sight in my Elk rifle. The velocity was quite a bit higher than I remembered, and, I couldn't match it with some new loads to go with them by a few hundred fps.
I pulled a couple of the bullets with a collet puller and they were really in there! A substantial difference in force from pulling "fresh" loads. Clearly the reason the velocity was up there.
These were Barnes TTSX's loaded in squeaky clean cases (wet tumbled and my notes don't say anything about excessive seating force and I wouldn't have continued if they didn't feel normal).
What can I do to keep this from happening once again (besides shooting up all my loads!) and still keeping consistent neck tension?
