250gr TMZs Versus 290 gr TMZs
I have been shooting 290 gr TMZs with pretty good luck but I decided to try some 250 gr TMZs. Unless the 250s shoot more accurately I think I should have stayed with the 290s. I will try them out, hopefully next week. I will print the balistics charts, that came on the box, for both loads. The 290s look superior at all ranges.

From 100 yds on there is no PRACTICLE difference in POI and quite alot more energy from the 290. (higher BC )
