what are your thoughts on the .25 conversion over the 209 primer? I've heard it improves rifle accuracy while reducing the amount of fouling to the breech plug. I am in the process of purchasing a muzzleloader and I was curious about all aspects of a muzzleloader.

It does not impress me much, I can not believe it could improve accuracy as far as I am concerned it only gets so good and I suspect I would have to go to a higher power scope and longer range to tell if it made any improvement.
As far as cleaner is concernedthats a expensive improvement to not have to clean around the breach. I suppose if you insisted on 777 and were fighting crudrings it might make some differance. Lee

It is another contraption I can do without.In my opinion it is a solution to a non-problem.

I purchased one last month and I think I will keep it... absolutlely no blow back - no black on the scope... and it is easier to use and extract the spent shell.

Accuracy? - It is still as accurate as it was...

The only thing I am not sure of yet is ignition of t7-2f in really cold temperatures. I takes a lot of heat to ignite the t7 in really cold weather.

It is expensive by my standards, but then again what isn't.
