I've been playing round with mouse guns for a month or so and have added 5 new toys to the safe. 3 of which are .25's. I'm loading RCBS 50 gr pills sized to .251 in a lubrisizer. Firstly, I am admittedly not the engineer type caster. I've never been to technical, and yes, I've never even slugged a bore. That said, I cast and shoot 10-12 calibers with almost no issues. Enter the Baby Browning. This little guy is slinging lead everywhere, even a few keyholes. My Mauser 1910 shoots the same loads like a laser. The Browning is in great overall condition with a near perfect bore. I even went so far as to break taboo and buy a box of factory ammo, and they shot with excellent accuracy. I would love some insight.
