I would like to agree with spaniel - I use the 25acp in my Omega and it has been flawless. Normally I shoot small rifle primers in it when/while shooting T7. I did find for me I need to convert the primer to small rifle Mag primer to get BH to ignite correctly a 100% of the time.
One thing there seems to be a Breech plug issue showing up with the use of BH in that it will/does eventually begain plugging the flash channel. I have only shot 1 bottle of it (dang 10 ozes) but I did not find that problem yet...
