Been loading for my new Tikka and had a pretty good night at the range. Been trying to get a load dialed in and think I' m pretty close. Problem is I shot 2 groups of 5 and the first shot is hitting high, with a cold barrel, and then as the barrel heats up the rest of the group is really good.

Anyone see this happen before? Are there any remedies to try? I' m shooting a 7mm Rem. Mag. with 160g Partition reloads on top of IMR 4831 pushing along around 3,000 fps.

Thanks for the help.

(edit)
This is with a dirty barrel [10+shots]. I' ve shot 3-shot groups that seem to be spread around 1.5 " . I' ve only shot 2 groups like this one below (last night) so I' ll shoot more to confirm. Seemed pretty consistant though.
