I bought a box of Mt. Baldy Bullet Co.'s 250gr Keith's. They are BHN 11, and sized .430". I loaded up 50 of them last week over 9.5gr of Unique, which should run a little over 1,000 fps or so. To make a long story short, they leaded the first 1.5-2" of the barrel pretty badly. I assume that it is gas cutting as I have read that excessive velocity causes leading the entire bore length.
I have since found out that older Model 29's have .432" chamber mouths, or throats, whatever you want to call them. So these bullets are smaller than the chamber mouths. I had read that the softer lead bullets would obturate to fit the hole, but apparently this did not happen.
So I am curious if there is anything I can do with these and not have them lead the bore? Shoot them slower, or maybe with more power? I have no idea. Brian Pearce has an article in Handloader Magazine on loading for the Model 29, and he mentions that he uses the BHN 8-10 range bullets in his targets loads that are below 1,000fps, and uses BHN 15-18 range bullets in the mid-range loading that I tried. So would shooting these over Bullseye in the 870fps range help?
Or should I give them to a friend and buy some properly sized bullets LOL?
Thanks,
Jared
