The 25acp conversion works great in my Omega. I also have the veri flame but they are hard to keep from loosing, especiallywhen target shooting ( they are the same size as a 209 ). The 25s are also much cleaner in the breach area. I made my own 25acp breach plug using an extra breach plug I had on hand, a drill press and a no. J drill bit. You can buy the lee auto prime and a 25acp shell holder for in the $15 range and a bag of 100 25acp brass for less than $11.00 ( at Midway ). You will have to go to a store that sells (because of the $20 has-mat fee) reloading supplies for the primers,for about $3. I set the depth of the hole, in the breech plug, so that my Omega closes a little harder than with 209, and havent had any trouble with factory length brass ( get a good deep dent in the primer).
