I have some questions about the .25 ACP breachplug conversion for my omega. (For those that don't know, this allows primed .25 brass take the place of 209 primers)

Who has used it - good/bad? Have you noticed the smaller ignition charge helping with accuracy as claimed but is the pistol primer enough to reliably make the gun go off in tough weather - 10 degrees below zero, etc?

What primers did you use - Magnum small pistol primers or regular small pistol primers. Would using one or the other make much of a difference?

What powder have you used with it? I am wondering if I can use BH 209...but its a bit tougher to ignite? The last thing I want is good range sessions, then a "pop" when I line up on a deer. I like to hunt in bad weather, snow, freezing rain, wind, subzero temps.
