In the June 2015 issue there is an article on imr4166, since I have been considering moving from 4064 to 4166 I was anxious to read the article. In the second paragraph the author states, referencing the introduction of new powders, " what makes this more than a ho-hum announcement is the fact that these powders are purported to be less temperature sensitive than many others, and they include the copper fouling reducer additive recently introduced in hogdons cfe 223 and cfe pistol." Ok so at this point my interest is peaked as these are the reasons I am considering the switch. My expectations are there will be some attempt to quantify how effectively it reducers copper fouling and how it handles extreme temperature changes. Nope, the rest of the article is mostly about the loss of velocity in various cartridges. It mentions how it shoots in 22-250, 06, 300wsm and others.. The key word is mentions, no factual data, no comparison to other powders and groups. Groups were "impressive", "decent", "exceptional results with extreme spreads in the teens with group sizes to match". Does this mean group sizes were in the teens? .
How do you miss the target by so much? Why intro the purpose behind the propellant and the never discuss it in the article??!
