[QUOTE="Jason millichamp, post: 1669105, member: 109739"] Hi. I have a tikka varmint in .260 that I've been shooting in competition matches.its had probably about 1200 rounds through it. I shoot lapua scenar 139 with lapua brass and br2 primers. I load 44.4 grns of ADI 2209 powder which is the same as H4350 I've been getting about 2830 fps. At a match I went to it was drizzling and I got big pressure signs on the case. Brass flowing into the extractor position on the case. I thought it was the moisture that increased the pressure. Then I shot it again on a dry day and continue to get press problems. So I shot it over a chrony and it's now spitting them out at 2920 fps. I only buy powder as I need it and during that time I've bought new powder on the way. Would the change in powder batches cause the massive change in pressure and speed or would it be something else. Thoughts anyone? [/QUOTE]
