I am not familiar with the .25 acp conversion but if there is a conversion available to you,
been thinkin about switching over to one of these ,anyone out there use one ? can you tell any difference? i dont know whether to beleive the hype about the 209 primers being too much bang or not .would rather hear from some guys who have made the switch and get the real story.
you first have to understand you're not converting to a more powerful powder charge,
the conversion to 209 primers is only the source of Ignition.
209 primers are currently the most reliable ignition source available today.
I hope someone can offer more info with the .25 acp breech plug Conversion.
