RE: .25 ACP ignition help
The VariFlame does allow for the use of a small pistol or rifle primer that doesn’t burn as violently (hot) as a 29 primer and my groups did tighten up by 2/3’s. Since I personally haven’t used the 25 ACP system I can’t make any vast judgments (good, bad or off the cuff) on that system but the VariFlame cups are easy to remove and I haven’t had any problems with them as long as I keep everything clean.
