Yes Sir!
I rebarreled my .338 RUM a few months ago and it would print everything (multiple bullets, powders, primes, etc) into about 1.25" or larger groups @ 100. Steve said to try the 236 grain Hammer Hunter, and I received my box earlier this week. It shoots every powder, charge, primer combo I tried into .75" groups, found my new hunting bullet.
Gonna try some of the Hammers in a buddy's semi-custom 30-06 as it has the same lack of accuracy affliction my .338 does.
