The following test results were obtained by shooting pellets from the Straight Shooters Pellet Sampler using a .177 caliber Beeman HW97K fitted with a Bushnell Elite 4200 4-16x40 scope.
The
testing was performed outdoors with only an occasional stirring of
leaves in the trees and with an ambient temperature of 97 degrees.
Shooting was done down the back of a 10 foot tall fence in order to
help reduce effect of cross-wind, and because this is the longest
length available on my property.
The target was 46 yards away and shooting was done with the gun laying on a gel mouse pad resting on a platform I attached to a bush. Ten shots were taken per pellet type. Every effort was made to use a consistent shooting approach. Pellets were seated using my finger rather than a special device.
The C-T-C measurement approach usually used for all ten pellets, but in a few cases all of the pellets but one grouped well, so the wild shot was intentionally excluded from the measurement (but noted).

From these results, it may be concluded that the most consistant performers from a .177 caliber Beeman HW97K are the Crosman Premier, JSB Straton, and JSB Exact, in that order. In shorter range testing (34 yard) the JSB Straton performed best, followed by JSB Exact and Crosman Premier.
Using Straight Shooters velocity tests as a guide, the following is a summary showing how the most accurate pellets stack up in terms of velocity, delivered energy, and ballistic coefficient:
