My repeat test of Sako TRG 22 ( with Kimber 8400 Tactical used for comparison ) took place this past Saturday at Gabriola Rod and Gun. In light rain and wind, the results from the TRG22 confirmed the findings of the previous outing at the PoCo range and the best formula of handloads again shot approx 1/4 MOA ( 0.275" at 100 meters versus 0.231" the previous week) for the 5 shot group. Again, rounds were single loaded and a group was fired from the Sako followed by a group from the Kimber etc etc. Since my 8x32x56 NSX has yet to arrive I was still using the Elite 6x24x50 on the Sako and a Falcon 4.5x18x56 on the Kimber ( when NSX arrives Falcon will be sold ).
In my TRG, the 175 gr SMK over 44 gr of Varget is preferred over the 168 SMK with any powder charge but the crucial factor seems to be seating depth - best results ( 1/4 MOA two weeks in a row ) being found with a COAL of 2.840. No combination of handloads or the FGMM failed to produce a five shot group under an inch with the worst group being approx 0.8 ( don't have notes with me for exact data ) which was, again, consistent with the previous experiment.
