I finally got my .25 barrel machined and installed, only have some Crow Magnums to shoot but boy do they slap the swinging targets. have it limited to about 20fpe, any more and you only get about 15 shots on a fill. The Lothar-Walther barrel is real accurate, much better than me at 30 yards. Now to find some good glass to put on it. The larger caliber sure makes a statement when it hits something, can't wait for that first rabbit to sneek into the yard, it's gonna knock clean over. If you can get a bigger bore barrel and give this a try.
