[QUOTE="Greyfox, post: 679276, member: 10291"] I just went through the same thing with my 260 Reminton. Initially I loaded 44gr.of H4831sc and had no problems using my FL sizing dye. I tried working up loads using some VLD's up to 46 gr. There were no pressure signs but no matter what I tried which included three different FL dyes, the cases were expanded near the base and would stick in the chamber. When I went back to my brass that wasn't overpressured , or new brass with my original 44gr.grain load I had no problems. Once the Lapua brass was over pressured, nothing would bring it back. Even overcamming excessively. It's possible that your new lot of H1000 was hotter than your original. I just had this issue with both H1000 and Retumbo and had to recalibrate my 6.5x 284 loads 2 gr. lower to get my original velocities. It is possible that the 92 gr. load you used with the new lot, which is pretty hot even with the older lots of powder, may have expanded your brass beyond resizing. You might try backing off a few grains using new brass and see if you still have the brass sticking. I don't know if this is the issue, but the fact that you didn't have any problems until you changed powder lots leads me to believe this should be looked at first. iMHO. [/QUOTE]
