How accurate is a typical rimfire pistol? Out of curiosity I mounted my Buckmark, with its 4″ Tactical Solutions barrel and 5″ AAC Element II suppressor, on my test stand and recorded shots simultaneously at 25 and 50 yards.
As usual, I digitized the paper targets using OnTarget TDS, and followed the statistical analysis outlined at ballisticaccuracy.com. The aggregated data and analysis are in this Excel workbook.
Ammunition | CEP Radius (MOA) | Average fps | fps Standard Deviation |
---|---|---|---|
SK Plus | 2.0 | 904fps | 20.0 |
Eley Target | 2.0 | 952fps | 11.9 |
Gemtech 42gr | 2.0 | 910fps | 15.0 |
CCI SV | 3.1 | 914fps | 16.2 |
Federal Champion HV | 4.7 | 1037fps | 14.6 |
I was surprised at how much more dispersion this gun shows than the 10/22 rifles I have tested. It’s certainly nothing to brag about: The 10-ring on NRA Bullseye Pistol targets (shot competitively with autoloading rimfire pistols) typically has a radius of 3MOA, and even with zero shooter error the good ammo here would only hit that 80% of the time.
