I sure do like mine, performs well with 200 gr ttsx or 225 tsx. Recoil is stiff but my rifle isn't one of the heavyweights either. Stainless 700 Bdl in a Rem stock. A friend of mine has the only other one known to be in Alaska, both were made by a professional barrel maker in AZ with a reamer I ordered out of OR. In 2009 a grown Alaskan Moose received 1 TTSX from a lasered 325 yds and promptly expired. He was good eating too! I have a 3-9 X 40 Pentax Lightseeker which has served me well. I don't shoot .338 and my 7MM is a SAUM (good for sheep or caribou), therefore I'm not sure about the comparison. I also have some cronygrapgh data at home tho I won't be there until 18 Jan. The fine folks in Nebraska made my dies from 3 fired cases. I'd be glad to share any more information I can about this rompin-stompin round.
