Bargain Imported Primer Comparison Ballistic Tests
by: Tom Armbrust, Ballistic Research
A number of my shooting buddies from the McHenry gun club have been asking me about the relatively new bargain basement imported shotshell 209 primers and how they compare in relative force to popular American 209 primers. Some of these primers have been on sale for as low as $15.00 per 1000—a great savings to say the least.
For the control load, the Winchester 209 primer was selected as over many thousands of shotshells tests in all gauges at Ballistic Research this primer is very hard to beat with the many various burning rates of powders and wad types.
This following load was assembled as a control target load:

Same components as above except:

Note that the Nobel Sport 209/686 showed the lowest velocity at 1165 FPS and pressure at 7360 PSI while the R10 209/G600 showed the highest velocity at 1198 FPS and pressure at 9680 PSI. So the velocity difference was 33 FPS and the pressure difference was 2320 PSI.
My hat comes off to the PMC Optima 209 primer with both the lowest velocity variation at just 9 FPS and lowest pressure variation at 500 PSI.
The Winchester 209 primer was a very close second with a velocity variation of 14 FPS and identical pressure variation of 500 PSI.
