Following some review of the recent Buckmark accuracy test, some readers wondered if the suppressor was hurting precision. Others, noting that Buckmark barrels are well known for their accuracy, wondered how the stock 5.5″ barrel would fare.
I ran the standard barrel through the same procedure as before. The aggregated data and analysis are in this Excel workbook, and the summary results with links to the 50-yard targets are here:
|Ammunition||CEP Radius (MOA)||Average fps||fps Standard Deviation|
|Federal AutoMatch||1.2||1053fps||19.0||Federal Champion HV||2.1||1073fps||20.5|
This pistol shot everything well. In fact, the best four loads tested would all be expected to hit inside a Bullseye 10-ring virtually 100% of the time.
Running the Tactical Solutions barrel without the suppressor seemed likely to help its score also, at least with some loads. At 4″, it gives up 40-50fps vs. even the 5.5″ barrel. But the accuracy of CCI SV went from CEP of 2.0 MOA to 1.3 MOA. Groups of Eley Club (essentially the same performance as Eley Target) showed CEP under 1.4 MOA. However, it was not able to tighten performance of the Gemtech load. (Detailed data were added to the spreadsheet from the previous test.)
